Tin Ore Extraction Mineral Processing Metallurgy

The flowsheet below Explains the Extraction of Tin Ore as shown by a study adapted to the concentration of a lode tin deposit.Cassiterite (SnO2) is very friable and special considerations to crushing and grinding of the ore are necessary to avoid an excessive production of fines. The Mineral Jig is an important feature of this flowsheet to recover the coarse free tin mineral as soon as liberated.

Copper extraction

Copper extraction. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite ), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation.

Ore Refining an overview ScienceDirect Topics

Placer mining involves excavation of river or stream sediments and the separation of valuable minerals by gravity, selective flotation, or by chemical extraction. Most solution mining is by heap leaching, in which the extractant solution is trickled over broken ore on the surface or in underground workings; less common is injection into underground aquifers.

purification of copper by electrolysis metal extraction

4a. The extraction of copper from copper ores and its purification by electrolysis. Copper is well below carbon (less reactive) and so can be displaced by carbon from its compounds eg copper oxides or sulfides. However, in practice, modern copper smelters can actually manage the extraction without using carbon (coke) and then electrolysis is usually used to purify the impure copper from the smelter.
