Iron ore beneficiation begins with the milling of extracted ore in preparation for further operations to recoveriron values. Milling operations are designed to produce uniform size particles by crushing, grinding,and wet or dry classification. The capital investment and operation costs of milling equipment are high.
Crushing is a multistage process and may use dry iron ore feed. Typically, primary crushing andscreening take place at the mine site. Primary crushing is accomplished by using jaw crusher or gyratorycrushers. Primary crushing yields chunks of ore ranging in size from 6 to 10 inches. Oversize material is passed through additional secondary crushers and classifiers to achieve the desired particlesize.
In iron ore beneficiation operation, the raw iron ore materials will be first reduced to small particle size. It may require crushing the material tomaximize the production of minus 2mm. According to SBMs experience in crushing technology, we recommended the installation of acone crusher to reduce the minus 100mm pebblesand a VSI crusher machine to fine crush the cone crusherproduct.
The iron ore crushers with low price are also used in the industrial minerals, mining, recycling and general quarrying industries. A widerange of materials are processed through SBM iron crushers worldwide. SBM experts can customize crushing solution in iron ore beneficiation according to your requirements. Here are some popular iron ore crusher machine types. Please contact us for more information.
According to different final products applications, varioustypes of crusher equipment are required, such as jaw crusher for primary crushing, impact crusher and hammer crusher for secondary crushing, cone crusher for secondary and tertiary crushing. Iron ore crusher prices are different according to crusher types and production capacities.
The VSI crusher for iron ore beneficiation uses a unique rock-on-rockcrushing action whereby the feed materialgrinds and impacts against itself, minimizingwear costs and maintenance down-time. Thisis especially important in applications such asiron ore processing where the feed material istypically hard and abrasive and wear costs arepotentially very high.
Jaw Crusher Jaw crusher is available with stationary, mobile and portable applications. The jaw crushers combine a high reduction ratio and increased capacity with any feed materials: from extra hard rock to recycled materials. This is achieved through several unique features such as higher crushing speed, optimized kinematics, a longer stroke and easy adjustment.

January 25, 2019, the Vale iron mine in Brazil experienced a dam break, which led to the closure of large-scale mines. At the same time, the two major mines in Australia, BHP and Rio Tinto, were affected by the hurricane to reduce their shipments.
Since the end of January this year, iron ore prices have risen sharply, far exceeding the increase in steel and other raw materials. Therefore, iron ore has become the most popular investment in the eyes of investors. In July 2019, the price of iron ore reached more than US$120 per ton.
For the time being, the investment prospect of iron ore is very bright. So what is the global reserves and distribution of iron ore? How much does it cost to build an iron ore processing line? This article will answer you in detail.
The data released by USGS in early 2005 showed that the global iron ore reserves were 160 billion tons, the reserves of mineral iron (ie, iron contained in iron ore) were 80 billion tons and the basic reserves were 180 billion tons.
The worlds iron ore is mainly reserved in Ukraine, Russia, Brazil, China and Australia. The reserves are 30 billion tons, 25 billion tons, 21 billion tons, 21 billion tons and 18 billion tons respectively, accounting for 18.8%, 15.6%, 13.1%, 13.1% and 11.3% of the worlds total reserves respectively.
In addition, Kazakhstan, the United States, India, Venezuela and Sweden also have rich iron ore resources, and their iron ore reserves are 8.3 billion tons, 6.9 billion tons, 6.6 billion tons, 4 billion tons and 3.5 billion tons, respectively accounting for 5.2%, 4.3%, 4.1%, 2.5% and 2.2% of the worlds total iron ore reserves.
The worlds mineral iron is mainly reserved in Brazil, Russia and Australia, with reserves of 14 billion tons, 14 billion tons and 11 billion tons respectively, accounting for 17.5%, 17.5% and 13.8% of the worlds total reserves. The sum of the reserves in the three countries accounts for 48.8% of the total reserves in the world.
Mineral iron reserves and basic reserves are the most representative of the richness of a countrys iron ore resources, so Brazil, Russia and Australia are the worlds richest iron ore resources. At the same time, it shows that although Ukraine and China have large reserves of iron ore, they have more lean ore and less rich ore.
Iron ore resources are mainly reserved in more than10 countries, and 90% of proven reserves are distributed in10 countries and regions. They are: CIS (proven reserves of 114 billion tons, of which Russia is more than 80 billion tons), Brazil (68 billion tons), China (50 billion tons), Canada (over 36 billion tons), Australia (35 billion tons) ), India (17.57 billion tons), the United States (17.4 billion tons), France (7 billion tons), Sweden (3.65 billion tons).
The global iron mine reserves increased from 232 billion tons in 1996 to 370 billion tons in 2006, an increase of 59.5% in 10 years. The total amount of iron ore resources in the world is estimated to exceed 800 billion tons (the amount of iron ore), and the iron content exceeds 230 billion tons and there is still great potential for future discovery.
The major countries of iron ore resources include Brazil, Australia, China, Russia, Kazakhstan, Ukraine, the United States, India, Sweden, and Venezuela. High-grade ore is widely distributed in Brazil, Australia, India and other countries. The low mining cost and relatively high grade of iron ore make these countries the major iron ore suppliers in the world.
Before dry selection, the lean iron ore requires millimeter-scale fine crushing by the fine crusher. If the particle size of the iron ore is not small enough in the crushing stage, low-grade iron ore is difficult to be selected later, which will cause serious waste of resources.
The common problem in the iron ore crushing production line is that the wear parts of the fine crusher are seriously worn out, and the repair and maintenance of the fine crusher are too frequent, which makes the production efficiency of the iron ore crushing production line lower.
Different iron ore has different features. According to these features, the crushers are made of different materials. Therefore, the prices of iron ore crusher are different. However, reasonable crushing processes and crusher can be used to save the cost investment and achieve the required crushing effect.
In the crushing process of lean iron ore, in order to obtain the best process configuration and the lowest crushing cost, it is necessary to master the relationship of particle size among the primary crushing, the secondary crushing and the fine crushing.
For medium and low hardness lean iron ore, the second crushing equipment can use the impact crusher. The iron ore impact crusher utilizes a plate hammer on a high-speed moving rotor to produce a high-speed impact on the iron ore fed into the crushing chamber. The crushed iron ore is thrown at a high speed in the tangential direction toward the counter-attack at the other end of the crushing chamber.
During this process, the iron ore will collide with each other, causing cracks and looseness. When the iron ore particle size is smaller than the gap between the counterattack plate and the plate hammer, it is discharged outside the machine.
For high-hardness iron ore, a cone crusher can be used for the secondary crushing equipment. The HXJQ short-headed cone crusher can achieve a fine crushing effect of 3 to 13mm, which can fully meet the requirements of dry selection and grinding. However, due to the high hardness of such iron ore, the impact on the wear parts is large, so ordinary crushing equipment is difficult to exert its advantage.
In areas with low power consumption, the sand making machine developed and produced by HXJQ can achieve the fine crushing effect of high hardness and high output iron ore. Not only can the iron ore particle size be reduced to improve the dry selection efficiency, but also the ball mill load and operating cost can be greatly reduced, and the ball mill production capacity can be improved.
The price of iron ore crushing production line is related to various factors such as equipment combination, output level, and quality. Of course, the quotation standards of different manufacturers will also be different. Customers also need to analyze specifically when purchasing.
The comparison found that the price of the iron ore crushing production line of HXJQ Machinery is the most economical and reasonable, ensuring that the production line has a long service life, less failure, high efficiency, good effect, energy-saving and environmental protection, and can keep its price lower than other manufacturers 6% to 7%.
At the same time, the HXJQ configuration plan is all-sided, and there is a wide variety of equipment in HXJQ Machinery. If you are interested in these crushing equipment, please submit your relevant information on the right side, we will arrange a professional engineer to answer your questions.
Product Introduction JXSC jaw type rock crusher is usually used as a primary crusher and secondary crusher to reduce the size of medium-hard materials to smaller physical size. Jaw rock crushers are capable of working with the mobile crushing station, underground crushing because of its related small volume. Capacity: 1-1120TPH Max Feeding Size: 120-1200mm Application Mining, metallurgy, building materials, quarrying, gravel & sand making, aggregate processing, recycling, road and railway construction and chemical industry, etc. Suitable Material Granite, marble,basalt, limestone, coal, quartz, pebble, iron ore, copper ore, etc.
40 years of manufacturing and engineering experience keep us innovative and knowledge in the rock break machines and its applications, which thus provide reliable industry rocks crushers and solutions for every customer using jaw crusher manufacturers JXSC machines to meet their production goals. The jaw crusher machine family consists of different sized models that are designed to bring maximum output with minimum cost. Some workplaces have limited conditions and are unable to provide electricity or are underpowered. According to these conditions, JXSC specially designed diesel jaw crusher. The diesel-jaw crusher is actually with electric, but the original jaw crusher was added with a diesel engine equipment that a dual-purpose crusher.
JXSC the crushers machine with a non-welded frame has been proved that it has outstanding solid and durable strength. All the alloy casting frame components turn out that with premium quality, wear-resistant property.
The design of pitman and long stoke improves productivity and reduction. A wider feeding material opening increases the volume of insulating material and makes the ore material entering the crushers crushing chamber smoothly. A sharp angle makes the materials flow down speed faster and reduces the wear cost. Besides, the strike force could be stronger thus increase the production efficiency as well as the reduction ratio.
Types of jaw crushers: on the basis of the stone break equipment size and capacity can divide into a heavy and small(mini) portable jaw rock crushers. According to the working principle can be split into single toggle and double toggle jaw rock crushers machine.
A series of jaw stone crushers use compressive and squeezing force for reducing materials. This physical force is created by the two jaw plates, one of which is a movable plate and another is fixed, both of them are made of manganese. A V-shaped cavity, crushing chamber, is formed and the hydraulic discharge gap width of the crushing chamber, we can determine the suited feeding material size and discharging size, the width of top feeding is larger than that of bottom discharging.
Jaw crusher is a heavy-duty machine that crushes hard materials. So its hence muse be robustly constructed. Crusher frame is made from steel or cast iron. The jaws are made of cast steel. The liners are made fromNi-hard, Ni-Cr alloyed cast iron or manganese steel which can replaceable and use to reduce frame wear. The cheek plates are also made from hard alloy steel and installed to the sides of the crushing chamber to protect the frame from wear.
The jaws can be made in smooth or corrugated, but often corrugated. Because the latter crushing the hard and abrasive ores is better. The angle between the jaws is usually less than 26. This is because a large angle will cause the particle to slip which non-crush.
It uses curved plates to avoid the near the discharge of jaw crusher blocking. The bottom of the swinging jaw is concave, and the relative lower part of the fixed jaw is convex. The materials reduction in size when nears the exit. So the material is distributed over a larger area, and the jaws plates wear less.
The type of crushed materials determines how to design the max amplitude of swing of the jaw and the amplitude adjusted by changing the eccentric. The length from 1 to 7 cm depends on the crusher machine size. Jaw crushers are supplied in sizes up to 1,600 mm (gape)1,900 mm (width). For coarse crushing application (closed set~300 mm), capacities range up to 1200 tph.
Jaw crusher parts must have some wear after a period of use, but the easily damaged parts will wear out more. The price of crushing equipment with the same specifications and handling capacity is different in the material of parts.
Guard Plate The guard plate is made of high-quality high manganese steel, which is located between the fixed plate and the movable plate. The whole body is mainly to protect the jaw crusher frame wall.
Toothed Plate Tooth plate is divided into movable and fixed tooth plate, but both is made from high manganese steel casting. In order to prolong its service life, its shape is designed to be symmetrical. That is when one end of the wear can be used to turn the head. The movable and the fixed teeth plate are the main parts for stone crushing. So the movable teeth plate is installed on the movable jaw to protect the movable jaw.
Toggle Plate The toggle plate is a cast iron piece that has been precisely calculated. It is not only a force transmission component but also the safety parts of the crusher. When the crusher falls into the non-crushing material and makes the machine beyond the normal load, the toggle plate will immediately break. Then the crusher machine stops operation, thus avoiding the damage of the whole machine. The toggle plate and the toggle plate spacer adopt the rolling contact model which less attrition under normal use. It just needs smear a layer of grease on the contact surface is ok.
Triangular Belt When the motor transmits power, the triangle belt is connected with the pulley and the grooved pulley of the motor to drive the eccentric shaft and make the moving jaw move back and forth according to the predetermined track.
The tooth plate of the most jaw crushers are made of manganese steel, bearing linings are made of babbitt alloy, sliding blocks are made of carbon steel, toggle plates are made of cast iron, springs are made of 60SiMn. Regular Inspection and maintenance of the machine can extend its service life. In order to reduce customer costs, we will generally be in the purchase of customers are advised to buy some spare parts. Because once the parts need to be replaced, the temporary purchase will take some time. The wait time may cause the entire breakage line to suspend operations, thereby increasing operating costs.
In short, the jaw stone crushers are mainly used for primary crusher, the crushing stone is relatively large. The types of crusher machine's chamber are deep and no dead zone. It improves that the feeding capacity and output. The crushing ratio is large and the product particle size is even. Shim type outlet adjustment device, reliable and convenient, large hydraulic adjustment range that increased the flexibility of the equipment. Simple structure, reliable work and low operation cost. The adjustment range of hydraulic discharge opening is large, which can meet the requirements of different users, low noise and less dust.
Impact crusher for crushing medium-hard stones, and mostly used for secondary crusher. The impact crushers have a big feeding port, high crushing cavity, high material hardness, big block size and little stone powder. Convenient maintenance, economic and reliable, high comprehensive benefit.

Nowadays, with ways of ore processing are getting more and more diversified and intelligent, the investment is not only limited to gold ore beneficiation but enlarged to many other items. From precious metals to coal, and to non-ferrous metals, investors can profit and bring more economic benefits to society.
Over 80 kinds of ores are widely used minerals in the world. Due to large output and high international trade volume, there are the several most common and important ores such as iron ore, copper ore, gold ore, bauxite, coal, lead&zinc ore, nickel ore, tin ore, and manganese ore, etc.
Nothing can replace iron ore in developing infrastructures as well as coal ore in the electricity industry, those ores making a great contribution to countries' economic growth. Gold ore mining ranks in a top position, attracting lots of investment for closed relations between the gold price and currency market.
The screening and crushing process is used to release useful minerals from the gangue. Different types of crushers reduce large sizes of raw ore into smaller ones, then vibrating screen with different mesh would help to get the desired size of ores. During the process, how many crushers need to be installed according to your real situation.
Usually, there are crushers with three crushing stages: primary crushers like jaw crushers, secondary crushers like cone crushers, roll crushers and impact crushers, tertiary crushers like compound crushers and fine crushers. Vibrating screens also have different types: Circular motion vibrating screens, horizontal Screens, high-frequency Screens, and trommel/ drum screens.
Only by crushers cannot get ore products with fine granularity, that's why mill grinding machines necessary in the beneficiation process. The mill grinding process is almost carried out in two consecutive stages: one is dry grinding (coarse grinding) and the other is wet grinding (fine grinding). The key grinding equipment are ball mills and rod mills, and the latter is now mostly used for wet grinding to finally produce fine and uniform ore products.
The beneficiation process is most crucial during the whole plant, helping people extract high value and pure ore concentrate products from ores no matter its grade high or low. The beneficiation process can be carried out in a variety of ways as needed but you ought to select a piece of optimal equipment to avoid inefficiency and waste in the entire process. The most common beneficiation equipment includes flotation machines, electrostatic and magnetic separators, and gravity beneficiation equipment.
Ore drying equipment may appear in any stage of a mineral processing plant (from raw ore-concentrate-finished product). The purpose of drying is to remove the moisture contained in the ore, ensuring the integrity of the product, and maximizing the value. In addition, drying process can also reduce product transportation costs and improve the economic efficiency of storage and processing.
