Copper Statistics and Information usgs.gov

Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasing share of copper is produced from acid leaching of oxidized ores.

Refining (metallurgy) Wikipedia

Electrolytic refining. The purest copper is obtained by an electrolytic process, undertaken using a slab of impure copper as the anode and a thin sheet of pure copper as the cathode. The electrolyte is an acidic solution of copper sulphate. By passing electricity through the cell, copper is dissolved from the anode and deposited on the cathode. However impurities either remain in solution or collect as an insoluble

Gold and silver are byproducts of the copper mining and smelting process. They follow the same production pathway as the copper ore from the mine to the smelter. At the refinery, the copper anodes (which contain gold and silver) are lowered into an acid solution. Gold and silver drop off into the bottom of the tank as electrolytic slimes.
