Copper Ore Concentration Process

Recovering Gold from Copper Concentrate via the ...

copper concentrate was signiﬁ cantly slower than in the other concentrate; therefore, the mode of occurrence of gold in the Pyhäsalmi concentrate was studied in more detail. About 20% of the gold in the copper concentrate is gravitative recoverable, as shown by Knelson preconcentration tests resulting in a heavy fraction with 92 ppm gold.

Electrowinning Copper Chemistry Tutorial

Copper ores are usually copper oxides, copper sulfides or copper carbonates. Most copper oxide ores do not contain a high enough percentage of copper to make direct smelting of the ore economically viable. Electrowinning can be used to extract the copper from these copper oxide ores. The process for extracting copper from copper oxide ores can ...
