Crushing is very important in beneficiation, because crushing can fully separate metal ore from gangue and provide condition for subsequent physical beneficiation. The crushed ore is more convenient for sorting and can improve the efficiency of beneficiation. Reasonable crushing technology can effectively reduce beneficiation production cost.
There are many different crushing processes depending on ores’ type, features and size demand. Generally, two-stage crushing process with coarse crushing + medium crushing or three-stage crushing process with coarse crushing + medium crushing + fine crushing is used. Coarse crushing use jaw crusher, medium and fine crushing use cone crusher or impact crusher. After multistage crushing, the final metal ore size is suitable for ball mill working, meeting the principle of "more crushing and less grinding".
As an experienced crusher manufacturer and solution provider, Sandmine always adheres customer demand-oriented principle, provides customers efficient and high-quality crushing equipment, economic and practical solutions, to help customers improve the metal ore grade, improve production efficiency, reduce operating costs, then increase operation revenue and profit
Suitable for production line solutions for iron ore, copper ore, gold ore, aluminum ore, manganese ore, lead-zinc ore and other metal mines
This process is for reference only. Depending on different material, usage and discharge size, we can customize the process and configure appropriate equipment for you.

Iron ore is an economically available mineral aggregate which contains iron elements or iron compounds. There are many kinds of iron ore, magnetite (Fe3O4), hematite (Fe2O3) and siderite (FeCO3) are the main kind for iron making. Iron ore is an important raw material for iron and steel production enterprises. Ore is gradually selected by crushing, grinding, magnetic separation, flotation, gravity separation and other procedures from natural iron. In the concentrator, crushing and grinding equipment investment, production costs, electric energy consumption and steel consumption often account for the largest proportion, so the quality of equipment and the convenience of operation and maintenance determine the economic benefits of the concentrator.
Copper ore is a mineral form in which copper is mainly in the form of compound and a few in the form of elemental. There are more than 200 kinds of copper minerals in nature, and the common copper minerals can be divided into three types: natural copper, sulfide ore and oxidized ore. Natural copper is rare in nature; Sulfide ore is the most widely distributed and is the main raw material for copper smelting, including chalcopyrite, bornite and chalcocite. Oxidized ore is mainly divided into azurite, chalcopite and malachite. Copper ore has a wide application range in various fields, such as power and electronics industry, machinery industry, construction industry, chemical industry, metallurgical industry, manufacturing industry and so on.
Gold ore refers to the ore containing gold elements or gold compounds mined by artificial or mechanical mining, which also contains other metal impurities. After beneficiation, gold ore becomes gold concentrate with high gold grade, and then becomes refined gold and gold products after smelting. In this process, crushing is one of the important part that cannot be ignored, and its significance is to meet the requirements of sorting machinery for the material particle size, to meet the separation requirements of useful minerals and gangue, to meet the requirements for the particle size, and to meet the concept of "more crushing and less grinding" in the mining field.
Aluminum ore is one of the main raw materials for aluminum smelting, mainly have diaspore, boehmite and gibbsite, the hardness is 2.5-3.5, relative density is 2.30-2.43. Aluminum ore has a wide range of applications, which can be used to refine metal aluminum, and can also be processed into various aggregates for military, aerospace, machinery and medical equipment. In addition, aluminum ores can also be made of high-grade refractory materials, refractory bricks, castables, special ceramics and industrial alumina. Aluminum ores'hardness is larger, it needs crushing, grinding and other procedures for smelting or other use
Manganese is widely distributed in nature, almost all kinds of ores and silicate rocks contain manganese, but the main manganese minerals mainly include pyrolusite, hard manganese ore, water manganese ore, brown manganese ore, black manganese ore, rhombosite and so on. Manganese ore is the largest amount of metal ore in the field of iron and steel metallurgy, mainly used in the production of silicon manganese alloy, ferromanganese alloy and other alloy materials, these materials are widely used in the production of stainless steel, special steel, structural steel, spring steel and other steel; Manganese ore can also be widely used in the production of batteries, dyes, medicine, pesticides and other chemical products.

Due to the trust to Chinese machinery manufacturing enterprises, customers chose Saandmine after inspecting a number of manufacturing enterprises. We specially sent engineers to Mongolia for field survey, give a reasonable production line configuration. Three sets of different models of same series multi-cylinder cone crusher is bright spot of this project. The customer give high praise to the full hydraulic insurance system, lubrication system and discharge port adjustment, saving time and labor and safer. At present, the production line is very stable.
Commissioning time : 2015
Location: Congo
Material: Copper ore
Finished size: 0-15mm
The project was successfully put into operation in April 2015. The customer visited another Sandmine iron ore crushing production line working site before purchase. The equipment runs smoothly, the quality is good, the failure rate is low, the capacity and profit are good. We designed two multi-cylinder full hydraulic cone crushers and one multi-cylinder spring cone crusher for customer, both of which are based on the principle of layer crushing, with low wear rate and good finished product shape. The production line has run for many years, we are regularly contact with the customer to know the working condition and get positive feedback from customer.
Please fill in the form with your information and specific needs, which will help us to get in touch with you as soon as possible and provide you suitable solution and a reasonable equipment quote.
