crusher for gold mining and processing line

crusher for gold mining and processing line

Gold is one kind of the rarest and most precious metals. It is with the features of soft and corrosionresistant. The color of gold is golden yellow, and with a metallic sheen. Its hardness is about 2 to 3. For physical characteristics, gold is with good ductility, high thermal conductivity and electrical conductivity. Since gold has excellent stability, good electrical conductivity and thermal conductivity, so the uses of it become wider and wider in the electronics industry. In the chemical industry, gold also has a unique purpose. It can be used as the materials in nuclear chemical plants, man-made fiber factory, and so on.And at the same time, gold is still has some gold consumption in the traditional industries, such as photography, pens, dental, and other industries.

Because of a wide range of applications, gold ore mining and processing developed greatly in recent years. Since the 21st century, the world's gold production stabilized at an average of 2,600 tons. Gold ore is very unevenly distributed on Earth. Though, there are more than 80 countries produce gold in the world, the gold productions are quite different among these countries. In 2004, the world's top 10 gold production countries are South Africa, USA, Australia, China, Russia, Peru, Canada, and so on. While gold production has increased in some countries, such as Australia, Peru, Indonesia, but gold production in South Africa, the United States and other gold producing countries has declined.

Gold ore beneficiation process includes preparing operations and sorting operations. Prepare job mainly consists of two processes, they are crushing and screening. Crushing process is mainly to crush the large of gold ore into small pieces, and to separate the clay mineral from metal particles. Screening process is mainly to screen the coarse particles which without gold out. Commonly, flat screen and cylindrical sieve are usually used as the gold ore screener. As for gold ore beneficiation, gravity separation method is mainly used. On the one hand, the proportion of placer gold (average 17.50 to 18.0 mm) is bigger than coarse grain (typically 0.074 to 2 mm). On the other hand, gravity separation method is one kind of relatively economical and simple beneficiation method. Jigging machine and shaking table are the commonly used beneficiation equipment of gold ore.

According to the survey, people usually adopt jaw crusher for primary crushing in gold plant. And then, adopt cone crusher and impact crusher for secondary crushing and fine crushing. In order to increase the production capacity, we need to adopt efficient gold production equipment and improve the processing technology.

PEW series jaw crusher is common gold ore primary crushing equipment. It is designed based on the traditional jaw crusher. It is suitable to process all kinds of medium-grained into small pieces. It is often associated with cone crusher, grinding mill and other equipment to form a complete gold ore processing line. Its structure is stable and reliable, so the performance of it is quite outstanding. The crushing chamber of it adopts a "V"-type structure, which effectively increasing the crushing area and improving the crushing rate and yield.

HCS series single cylinder hydraulic cone crusher is a high efficiency gold ore crusher.Compared with similar products, it has great advantages. It can meet the demands of gold ore medium and fine crushing. It is with the features of simple structure, reliable performance, and stable operation. And this cone crusher is equipped with hydraulic adjustment and hydraulic protection device. Soit is easy to clean the chamber. As a result, it can effectively save the downtime.

rock crushers for commercial gold mining operations

rock crushers for commercial gold mining operations

Rock crushers usually hold the rocks to be crushed in between two solid surfaces and apply a force that forces the molecule of the materials to separate or change alignment. Rock crushers are extensively applied in the mining sector where rocks containing the ore are crushed before the mineral is extracted.

In most cases, mining operations may have more than one crusher depending on the desired outcome of the crushing process. The primary crusher handles course rocks while the secondary, tertiary and sometimes the quaternary works on finer gradations that can allow for effective extraction of minerals.

Unlike the alluvial gold found in river beds, most of the gold mined underground is found in hard rocks that contain a lot of other materials. To get pure gold from these gold-bearing rocks has to be processed. The first stage is to crush the rocks to smaller fine gravels that will allow for gold molecules to be extracted.

The crushing of gold-bearing rocks is not as easy as it may seem. This is because the rocks have to be crushed to very fine gravels that can allow for gold molecules to be dissolved in mercury or any other chemical used to extract gold from the ore. What this means is that in large scale mining the mines may have more than one crusher (primary, secondary and tertiary crushers) in order to achieve the desired crushing levels.

This type of rock crusher employs the compressive force to break up larger rocks into smaller pieces. The crusher has two vertical jaws; a fixed jaw and a swing jaw. The rocks to be crushed are filled into the crushing chamber (the gap between the two jaws) and then a weighted flywheel is used to create an eccentric motion in the swing jaw to provide the required inertia to crush the rocks.

Jew crushers are designed to be heavy duty machines used as the primary crushers in many mining operations. Because of this, the crushers are robustly constructed. The outer shell of the crusher is made from strong steel or cast iron while the jaws are fashioned from hardened cast iron with a Ni-hard or manganese steel removable lining.

Dodge crushers are designed with the swing jaw fixed at the lower end enabling material to be crushed progressively as they move down the crushing chamber. Dodge crusher as more effective in crushing tough and abrasive rocks.

The gyratory crusher works on the same principle as the jaw crusher but has a conical head and a concave surface. The crushing chamber is lined with a hardened manganese steel material. The rock crushing is caused by a circular movement in the crushing surface and the materials are progressively crushed until they are of a smaller size that can fall off the narrow end of the chamber. The gyratory crusher is often used as either primary or secondary crusher in many mining operations as it delivers sufficient force to crush large ore bearing rocks.

The cone crusher is the most widely used crusher in mining operation across the world. The crusher is designed in a similar fashion as the gyratory crusher but the crushing chamber is less steep with the sides near parallel.

Crushing is done by a gyrating spindle as the rocks move from the wider upper section until they are small enough to fall off the lower narrow opening. Cone crushers are perfect for hard to mid hard ore bearing rocks and are highly productive making it perfect for use in crushing intensive mines. There four major types of Cone Crushers

The Symons cone crusher is widely used to crush medium harness to very hard rocks. Its size allows it to be used as a secondary or tertiary crusher in mining operations and as a mobile crusher in building and construction and chemical industries.

As the name suggests a single cylinder hydraulic cone is made up of a single crushing cone, a hydraulic control system, an eccentric shaft, bowl liner, adjusting sleeve and a hydraulic safety system. It is perfect as a secondary or a tertiary crusher in mining.

Impact crushers do not use pressure to crush rocks but rather employ impact. The material is placed in a cage where an impact is used to crush them. The cage has narrow openings to allow crushed rocks of the right size to escape. There are two major types of impact crushers:
