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.

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.
