Mineral processing Wikipedia
Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the

Open Pit Mining Mineral Processing Metallurgy
If the deposit is flat or is dipping and not outcropping to the surface that is located a certain shallow depth from it, then the overburden becomes waste rock in the surface mining process. When we mine a deposit, it becomes easy to think that it''s not practical to excavate or to work with machinery and equipment on sloping surfaces.

Iron Ore Mining Techniques, Metal Extraction,
MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale. The float ore area is dug up manually with picks, crow

Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface
