There are various kinds of ores. According to properties and industry usages, ores can be classified as metal ores, nonmetallic ores and flammable ores. According to the metalliferous types, ores can be classified as monomineral ore multimineral compound ore. The mining of ores usually follows the following steps: crushing and screening, grinding and classifying, material separation, concentrate and tailings dispose, beneficiation dispose and so on.
Crushing and screening equipment
At present, the medium and small ore mining factories adopt two stages or three stages crushing circuit; the large scale mining factories adopt three stages crushing circuit; some large scale mining factories adopt four stages open circuit crushing circuit because of the big raw material block. Classic crushing and screening equipments used by the ore mining factories are: jaw crusher, impact crusher, cone crusher and sand maker.
Grinding and classifying
In the ore mining plant, ore grinding follows ore crushing and continuous crush and grind the ore. It is an important part of beneficiation. The quality of the grinded product directly affects the concentration index. The ore grinding process consisted by grinding machine and classifier called ore grinding classifying process, which makes the final product granularity fit the requirement of next procedure. Ore grinding process should be simple, flexible, and have certain adaptability. Main equipments of ore grinding process are: ball mill, grid ball mill, wet type ball mill, Raymond mill, vibrating screen, and spiral classifier.
Material classifying
There are three main ways to classifying material: reselection, magnetic separation, flotation separation, electric selection, and chemical separation. According to the physical and chemical properties of ores, the different methods of separation can be chosen. The main equipments are magnetic separator, flotation machine, spiral chute, shaking table and etc.
