Given the ubiquitous coverage of the COVID-19 pandemic, immune support is at the forefront of everyones minds. Various vitamins and minerals are flying off the shelf because of their recognized immune-supportive qualities, including zinc, vitamin C, and vitamin D.*1
When supplementing any nutrient, its important to consider the appropriate amount to take. If intake is too low, then the desired results might not occur. If supplementation is too high, then negative side-effects could occur.
The Recommended Daily Allowance (RDA) suggests a nutrients daily average intake. Although the RDA is the amount needed to prevent a deficiency, its not necessarily a therapeutic amount. The RDAs are specific to life stage and gender group for healthy individuals.2
The Tolerable Upper Intake Level (UL) is the highest daily amount of a nutrient that is unlikely to cause an adverse effect. This limit applies when a nutrient is being consumed at higher, therapeutic levels for an extended period of time, such as in cases of deficiency, illness, and research participation.2
Zinc supplementation plays an important role for individuals who are deficient or who dont get enough zinc from their diet. Since our bodies cannot make zinc, it is considered an essential mineral one that must be obtained from food or supplementation. At any given time, our bodies store 2-3 grams of zinc in our bones and muscles. Some of that zinc is depleted each day as it is used in a variety of functions throughout our bodies.2-4
A low level of zinc can be associated with age, eating a vegetarian or vegan diet, compromised immunity, severe burns, and intravenous nutrition. Although severe zinc deficiency is uncommon, a mild deficiency can have a wide range of symptoms due to the use of zinc in so many bodily functions.2
The body uses copper in energy production and to support bone, skin, neurological, and cardiovascular health.* Along with zinc, copper is a component of superoxide dismutase, an important antioxidant enzyme utilized by the immune system.* Although copper deficiency is rare, it can result from high levels of zinc intake because of a decreased ability to absorb and use copper from the diet.2,5-13
Therefore, several research studies have investigated the relationship between zinc intake and copper status. In those studies, the amount of zinc and the length of time taken were analyzed. A daily intake of 60 mg of zinc for 10 weeks (well above the UL) was associated with a decrease in copper status.13
In this study, the zinc intake came from 10 mg from the diet and 50 mg from a zinc supplement. Other sources of non-dietary zinc intake, in addition to zinc-specific supplements, include multi-vitamin/mineral supplements, zinc lozenges, and denture paste.
Additional studies indicate copper supplementation along with zinc helps balance absorption of both nutrients.14Many alternative and integrative practitioners recommend a ratio of 15 mg of zinc to 1 mg of copper similar to the ratio achieved if you remain within RDA guidelines.
For example, the average recommendation for zinc is 11 mg per day for healthy adults, slightly more or less based on gender and pregnancy or lactation status. For copper, the average recommendations is 1 mg daily for healthy adults.2If you are taking a zinc supplement daily, then it may be time to consider the addition of a copper supplement as well. Or you can take a multi with an optimal balance of zinc and copper.

Copper and zinc are two of the most important minerals needed by our bodies. Both of these minerals can be naturally supplemented by the food we eat and the water we drink. These minerals work hand in hand in many bodily functions like immune and nervous system response and proper digestion.
However, many people tend to forget the need to achieve balance when it comes to copper and zinc. In this article, we discuss one of the most commonly observed mineral imbalances in clinical practice, copper and zinc's individual functions in the body, the factors that affect copper and zinc balance, and how to balance copper and zinc intake.
Zinc is considered one of the most important trace elements in the body. Within the past five decades of scientific research, it has been determined that there are more than 3,000 zinc proteins present in the body. Later discoveries have linked zinc's importance to the proper functioning of more than 300 enzymes and 1,000 different kinds of proteins essential for coding human DNA.
The most prominent processes for which zinc is an essential ingredient include DNA coding, cell division, anti-oxidation, brain growth and development, immune system function, protein synthesis and wound healing. Zinc-deficient newborns can have birth defects and metabolic disorders, and in older people zinc deficiency can be linked to learning disabilities, mental sluggishness, delayed wound healing, diarrhea, growth retardation, hair loss, eye and skin lesions, poor immune function, weight loss, impotence, as well as depression and anxiety.
According to the Food and Nutrition Board, the average recommended dietary allowance of zinc is 11 mg/day for adult males (14 to 70 years old and above) and 8 mg/day for adult females (14 to 70 years old and above). Other life stage groups such as infants, pregnant and lactating women, and children have varying zinc requirements. The body stores zinc for only a short period of time before it gets excreted through urine and fecal matter, so it is important to have a continuous zinc intake.
According to research, copper plays a pivotal role in the different chemical processes of the body. Processes such as oxidation reduction (or the transfer of electrons between living cells), iron absorption, defense against oxidative stress (which happens when the amount of free radicals overwhelms repair processes of the body) and immune function all require copper. Additionally, copper contributes to carbohydrate metabolism and is found in the tissues of body parts such as the liver, brain, kidneys and hair.
Although rare, copper deficiency can occur and cause a decline in mental performance, as well as create mood and behavioral disorders. In fact, a recent study correlates sufficient copper intake with the normal formation of brain neurotransmitters in the nervous system. Clinical signs of copper deficiency may include anemia (the type that is unresponsive to iron supplementation), an abnormally low number of white blood cells (neutropenia), osteoporosis and other bone development abnormalities.
According to the Food and Nutrition Board, the average recommended dietary allowance of copper for both adult men and women (19 to 70 years old and above) is 900 ug/day. Other life stage groups such as infants and children have lower copper requirements, while pregnant and lactating women have higher copper requirements.
Zinc deficiency is more common than copper deficiency. Some people are also more likely to have copper overload compared to others, especially people who have or are suffering from chronic stress, slow metabolism, adrenal insufficiency or high estrogen levels.
According to research, the ideal zinc to copper ratio is 8:1, with an acceptable range from 4:1 to 12:1. Maintaining this ratio is essential to maintaining good health. Although there is no quick way to determine your zinc to copper ratio aside from conducting laboratory tests, assessing symptoms can be a good way to determine whether you may possibility have a copper to zinc imbalance. The following, which were enumerated in recent research studies, are the most likely symptoms of copper and zinc imbalance:
A balanced copper to zinc ratio plays an important role in maintaining a healthy immune system, and a lack of balance can potentially act as an early indicator of certain health disorders. First, the ratio can be used as a measurement of a person's oxidative stress levels. In fact, a recent study revealed that the body becomes unable to produce superoxide dismutase, an enzyme primarily responsible for fighting oxidative stress, when there is an imbalance between copper and zinc. The same study also found that zinc levels drop significantly during a chronic illness.
Proper copper to zinc ratio is also vital to brain health. A recent study correlated Alzheimer's disease to high levels of copper and relatively low levels of zinc. The findings were made by screening approximately 407 different scientific investigations from 1978, 44 of which met all of the inclusion criteria. Statistically, it has been found that there is a stronger relationship between copper and zinc levels and Alzheimer's disease, as compared to iron and zinc levels and Alzheimer's disease.ADHD and ASD in children are also correlated to a higher copper to zinc ratio. A recent study investigated the relationship between the levels of certain trace elements like copper, zinc, selenium, lead, as well as the copper to zinc ratio using 108 children, 58 of which were diagnosed with ADHD. The study found that there were lower levels of zinc and a higher copper to zinc ratio in children with ADHD compared to the healthy group, indicating a relationship between copper and zinc levels and ADHD.A different study was conducted using 120 children, 60 of which were children with ASD, to determine the relationship between a copper to zinc ratio and ASD. It was concluded that there is a strong relationship between the severity of autism and increased copper to zinc ratio, as researchers found that children with ASD had a significantly higher average serum level of copper and a lower average serum level of zinc compared to the healthy group.More studies have been conducted suggesting that having a high copper to zinc ratio can influence other areas of health, particularly that of elderly people.
It is essential to consult with a health provider if you suspect that you have a copper and zinc imbalance. By doing so, you will have a clearer picture of your current mineral balance status. There are also various tests available, such as serum, urine and hair mineral analysis.In addition to consulting with a health provider, you may also start making positive lifestyle changes to maintain your health and resolve any issues. Keep in mind that it is important to make such changes cautiously and with the advice of your health provider, as everyone has a unique physiology. Here are the things you can do to balance your copper and zinc intake:1. Increase or decrease your intake of the following copper-rich foods, as needed: liver, seeds (sesame and sunflower), oysters, cocoa powder, beans (soybeans, adzuki, kidney, white and mung beans), nuts (cashew, brazil, pine and hazelnuts), lentils and buckwheat.2. Increase zinc intake by asking a certified health provider about zinc supplements. Avoid consuming substances that deplete zinc such as alcohol, sugar and grains. 3. Increase or decrease your intake of the following zinc-rich foods, as needed: oysters, organic grass-fed beef, seeds (sesame, pumpkin and sunflower), beans (adzuki, navy, black and white), wild rice, nuts (peanuts, pine and cashew), teff, split peas and lentils.
4. Manage your stress levels to maintain optimum health of the adrenal glands. The adrenal glands work hand in hand with the liver in producing ceruloplasmin, which is an enzyme that binds with copper and transports it within the body through blood plasma.5. Make sure you are consuming other essential nutrients that can be taken to help deal with excess copper intake, such as manganese, vitamin A, C and B6. Antioxidants such as alpha-lipoic acid and glutathione may also help in removing excess copper from the body. The body's glutathione levels play an important part in immune health and detoxification. When there is a high copper to zinc ratio, the bodys natural ability to produce this antioxidant is decreased.
As you may have noticed, many of the foods listed above contain both copper and zinc and have a good ratio of both minerals. For instance, a 100-gram serving of Brazil nuts contains approximately 4.7 mg of zinc and 2 mg of copper. Eating these foods in moderation can help maintain a healthy copper and zinc balance.
Zinc and copper are essential minerals that work hand in hand for many different beneficial processes of the body. Consuming them and making them a part of your regular diet is important; but bear in mind that it is also important to maintain a proper ratio to avoid any potential health issues. To do so, always make sure to get adequate amounts of each mineral, primarily from natural sources. Lastly, if you feel that you have a zinc and copper imbalance, it is best to consult with a health professional as soon as possible, as there are many tests available that can accurately assess both your zinc and copper serum levels.

This research was aimed to investigate the leaching behavior of zinc and copper from a porcelain stone tailings sample using RSM-CCD modeling. The synergetic and individual effects of five main factors including liquid/solid ratio, sulfuric acid concentration, agitation speed, leaching time, and temperature were examined on the recoveries of zinc and copper. For this purpose, two 2F1 models with R2 values of 0.9341 and 0.8693 were developed for the relationship between the leaching efficiencies of copper and zinc and effective terms, respectively. The results indicated that the leaching process was significantly influenced by the interactive effects between factors. The leaching recoveries increased by increasing all factors in the range studied. However, the recoveries were nearly independent of the agitation rate, indicating surface chemical reaction as the leaching kinetics controlling step. It was also found that the linear effect of temperature, the interaction effect of leaching time with liquid/solid ratio, and the interactive effect between sulfuric acid concentration and agitation rate had the greatest impact on the leaching rate of copper. Additionally, the linear effect of temperature and the interactive effect of temperature with agitation speed and liquid/solid ratio were distinguished to be the most effective factors on the recoveries of zinc. Moreover, the optimization was performed using desirability function approach, and the highest recoveries of copper (73.95%) and zinc (81.02%) were obtained at an acid concentration of 10%, 300rpm agitation rate, 10mL/g liquid/solid ratio, 35C temperature, and 75min leaching time.

How many types of ball mill 1. Based on the axial orientation a. Horizontal ball mill. It is the most common type supplied from ball mill manufacturers in China. Although the capacity, specification, and structure may vary from every supplier, they are basically shaped like a cylinder with a drum inside its chamber. As the name implies, it comes in a longer and thinner shape form that vertical ball mills. Most horizontal ball mills have timers that shut down automatically when the material is fully processed. b. Vertical ball mills are not very commonly used in industries owing to its capacity limitation and specific structure. Vertical roller mill comes in the form of an erect cylinder rather than a horizontal type like a detachable drum, that is the vertical grinding mill only produced base on custom requirements by vertical ball mill manufacturers. 2. Base on the loading capacity Ball mill manufacturers in China design different ball mill sizes to meet the customers from various sectors of the public administration, such as colleges and universities, metallurgical institutes, and mines. a. Industrial ball mills. They are applied in the manufacturing factories, where they need them to grind a huge amount of material into specific particles, and alway interlink with other equipment like feeder, vibrating screen. Such as ball mill for mining, ceramic industry, cement grinding. b. Planetary Ball Mills, small ball mill. They are intended for usage in the testing laboratory, usually come in the form of vertical structure, has a small chamber and small loading capacity. Ball mill for sale In all the ore mining beneficiation and concentrating processes, including gravity separation, chemical, froth flotation, the working principle is to prepare fine size ores by crushing and grinding often with rock crushers, rod mill, and ball mils for the subsequent treatment. Over a period of many years development, the fine grinding fineness have been reduced many times, and the ball mill machine has become the widest used grinding machine in various applications due to solid structure, and low operation cost. The ball miller machine is a tumbling mill that uses steel milling balls as the grinding media, applied in either primary grinding or secondary grinding applications. The feed can be dry or wet, as for dry materials process, the shell dustproof to minimize the dust pollution. Gear drive mill barrel tumbles iron or steel balls with the ore at a speed. Usually, the balls filling rate about 40%, the mill balls size are initially 3080 cm diameter but gradually wore away as the ore was ground. In general, ball mill grinder can be fed either wet or dry, the ball mill machine is classed by electric power rather than diameter and capacity. JXSC ball mill manufacturer has industrial ball mill and small ball mill for sale, power range 18.5-800KW. During the production process, the ball grinding machine may be called cement mill, limestone ball mill, sand mill, coal mill, pebble mill, rotary ball mill, wet grinding mill, etc. JXSC ball mills are designed for high capacity long service, good quality match Metso ball mill. Grinding media Grinding balls for mining usually adopt wet grinding ball mills, mostly manganese, steel, lead balls. Ceramic balls for ball mill often seen in the laboratory. Types of ball mill: wet grinding ball mill, dry grinding ball mill, horizontal ball mill, vibration mill, large ball mill, coal mill, stone mill grinder, tumbling ball mill, etc. The ball mill barrel is filled with powder and milling media, the powder can reduce the balls falling impact, but if the power too much that may cause balls to stick to the container side. Along with the rotational force, the crushing action mill the power, so, it is essential to ensure that there is enough space for media to tumble effectively. How does ball mill work The material fed into the drum through the hopper, motor drive cylinder rotates, causing grinding balls rises and falls follow the drum rotation direction, the grinding media be lifted to a certain height and then fall back into the cylinder and onto the material to be ground. The rotation speed is a key point related to the ball mill efficiency, rotation speed too great or too small, neither bring good grinding result. Based on experience, the rotat
ion is usually set between 4-20/minute, if the speed too great, may create centrifuge force thus the grinding balls stay with the mill perimeter and dont fall. In summary, it depends on the mill diameter, the larger the diameter, the slower the rotation (the suitable rotation speed adjusted before delivery). What is critical speed of ball mill? The critical speed of the ball mill is the speed at which the centrifugal force is equal to the gravity on the inner surface of the mill so that no ball falls from its position onto the mill shell. Ball mill machines usually operates at 65-75% of critical speed. What is the ball mill price? There are many factors affects the ball mill cost, for quicker quotations, kindly let me know the following basic information. (1) Application, what is the grinding material? (2) required capacity, feeding and discharge size (3) dry or wet grinding (4) single machine or complete processing plant, etc.
Our automatic production line for the grinding cylpebs is the unique. With stable quality, high production efficiency, high hardness, wear-resistant, the volumetric hardness of the grinding cylpebs is between 60-63HRC,the breakage is less than 0.5%. The organization of the grinding cylpebs is compact, the hardness is constant from the inner to the surface. Now has extensively used in the cement industry, the wear rate is about 30g-60g per Ton cement.
Grinding Cylpebs are made from low-alloy chilled cast iron. The molten metal leaves the furnace at approximately 1500 C and is transferred to a continuous casting machine where the selected size Cylpebs are created; by changing the moulds the full range of cylindrical media can be manufactured via one simple process. The Cylpebs are demoulded while still red hot and placed in a cooling section for several hours to relieve internal stress. Solidification takes place in seconds and is formed from the external surface inward to the centre of the media. It has been claimed that this manufacturing process contributes to the cost effectiveness of the media, by being more efficient and requiring less energy than the conventional forging method.
Because of their cylindrical geometry, Cylpebs have greater surface area and higher bulk density compared with balls of similar mass and size. Cylpebs of equal diameter and length have 14.5% greater surface area than balls of the same mass, and 9% higher bulk density than steel balls, or 12% higher than cast balls. As a result, for a given charge volume, about 25% more grinding media surface area is available for size reduction when charged with Cylpebs, but the mill would also draw more power.
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.
Compared with grid type ball mill, overflow type ball mill can grind materials finer even though its grinding time is usually longer. So it can make finer particle products. Hence the grid type ball mill is mainly used for primary stage of grinding while overflow type ball mill is mainly used for the secondary grinding.
Ball mill Advantages: 1Jack-up device, easy maintenance; 2The hydrostatic and hydrodynamic bearings ensure the smooth operation; 3Low speed transmission is easy for starting and maintenance; 4The oil-mist lubrication device guarantees reliable performance of bearings; 5The air clutch adopts the flexible start-up model./5According to the customer demand, manganese steel liner and wear-resistant rubber liner can be customized with good wear resistance, long service life and easy maintenance.
The grinding system uses either 'open circuit' or 'closed circuit'. In an open circuit system, the feed rate of materials is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer ones and sent back for further grinding.
