Copper Mining and Extraction Sulfide Ores

Gold, silver, platinum and tin are insoluble in this electrolyte and so do not deposit on the cathode. They form a valuable ''sludge'' that collects under the anodes. Soluble impurities of iron and nickel dissolve in the electrolyte, which has to be continually purified to prevent excessive deposition onto the cathodes, which would reduce the purity of the copper.

The Source of Gold

Most people think of gold nuggets and such as the source of gold, but the truth is that very little of the new gold produced comes from nuggets - nearly all newly mined gold comes from ores mined from the natural hard rocks that contain gold in tiny, even microscopic particles. This article is created to describe what these ores are like.
