Electrowinning of gold copper ores - Hydrometallurgy ...

Hie guys. I am having problems with the amount of copper associated with our ore. The copper content is not high enough for economic recovery but its high enough to cause problems in our CIP circuit and electrowinning. A typical elution would produce about 4kgs of gold and 5kgs of copper. The coppe

Extracting Gold | HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to

Electrowinning - ScienceDirect

In gold ore–processing applications, some research focus has been on the influence of impurities such as copper,1., 2., 3. calcium, 4 and anode impurities5., 6. on gold electrowinning efficiency. Additional effort has been toward incrementally increasing cell cathode volumes with basketed or nonbasketed packed-bed cells in an effort to increase cell efficiencies beyond the norm. Alternative ...

Carbon Adsorption In Recovery Of Gold - Mine …

The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton. If the ore is a high grade, it may be feasible to tank leach it. By high grade, it would probably be ...
