Sulfide Mining Overview - sosbluewaters.org
milling, the ore is crushed to mineral sized particles using metal balls or rods to pulverize ore to the consistency of sand, silt, or clay. 24 Next, the sand-like substance is mixed with water to create slurry which is run through the floatation process. In floatation ore slurry is run through vats which contain a chemical reagent.
Copper Sulfide Ore Flotation Technologies - Xinhai
Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as “collect early, loss early” and “more crushing and less grinding”.

Chemistry Tutorial : Copper Smelting
A typical copper ore contains between 0.5% and 2.0% copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC.
Nickel processing | Britannica.com
From sulfide ores. Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation. In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles.

What is roasting of a sulfide ore? - Quora
Jun 21, 2018· After the concentration or dressing of ore, chemical treatment follows, to get it to a metal or to its oxide so that we can easily reduce it to its metallic form. To convert sulphide ores to their respective oxides, the process of roasting is used( this is done because reducing sulphide directly, isn't the best way to go ahead).
Gold extraction - Wikipedia
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore..
