As is known to all, the earth's crust is rock, which is a kind of composition mineral collection being made up of one or more mineral. By natural physical chemistry reaction or biological chemistry reaction, the crust generates natural elements with solid production of chemical composition or physical properties .And that forms minerals, the natural elements (such as gold, graphite, sulphur) or natural compounds (such as magnetite, chalcopyrite, quartz). There are various kinds of minerals and the minerals for human utilization called useful minerals. Ore concept is developing, with the growth demanding of the economy, resources distribution changes and the development of science and technology, more of the rocks may be upgraded to ore. At present in China, for example, the mineral collection with iron of 20% or more can be used as iron ore; And iron content less than 20% was divided into the rock. As the same, the definition of the gangue minerals is relative, too. It also changes along with the change of resources and economic and technological condition. 

There are many kinds of minerals. Based on the nature of mineral and industry uses, ores are classified into metal ore, nonmetalliferous ore and flammable machine rock. According to the types of metal containing, ores can be divided into the single metal ore, multi-metal composite ore. Ore mining usually through the following steps: crushing and screening, grinding and classification, material separation, concentrates and residue processing, dressing conduction, etc. 

Crushing and screening equipment 

At present, the medium and small ore mining factories adopt second paragraph or three-stage crushing process; Large scale ore mining enterprises adopt three-stage crushing process; As the block of undressed ore is too big, some large factories also use four sections of broken open process. The typical crushing and screening equipments in ore mining plant are jaw crusher, impact crusher, cone crusher, and sand maker. 

Grinding and classification 

In the ore mining factory, grinding operation is falling behind the crushing processing. However, this operation continues crushing processing to ore is an important part of the ore separation. The quality of the grinding product has direct impact on the level of the choosing index. The combination of grinding machine and classifier grinding process is called a ore-milling classification process. The grinding process should make its final product size up the following operation needs. Besides, the grinding process should be simple, flexible and has certain adaptability. The main grinding process equipments are ball mill, grate ball mill, wet grinding machine, Raymond mill,  autogenous mill, semi-autogenous mill, vibrating screen and spiral classifier, etc.

Material separating 

Material separating mainly includes three patterns: heavy election, magnetic separation, the flotation, electric separation, pick processing, the chemical separation and microbe mineral processing. According to physical and chemical property of the mineral stone, we choose different ways. The main production equipments are magnetic separator, flotation separator, screw chute, concentrator table, high strength magnetized magnetic separator, etc. 

Our company adheres to the modern enterprise's scientific management method. We are best manufacturing and constant innovation. There are more than 10 kinds series of the products , including crusher, sand maker, ore dressing plant, ball mill, dryer, rotary kiln, milling machine, etc. And we provide you dozens types of broken, grinding, dressing and sand making equipment with different specifications. They are widely used in mining, building materials, bridges, coal, chemical industry, metallurgy, refractory materials and other industries.
