The Extraction of Copper
The copper(II) ions are removed again from the organic solvent by reaction with fresh sulfuric acid, producing a much more concentrated copper(II) sulfate solution than before. Electrolysis of the new solution. Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below).

Gold processing | Refining, Smelting & Purifying | Britannica
The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain. The advent of Christianity somewhat tempered the demand for gold until about the 10th century.

Gold in Quartz
In many cases, the gold minimum content will be even higher, depending on the circumstances of the miner, the capacity of his equipment and the type of ore processing he needs to do to recover it. Normally the small-scale miner is seeking free gold and often does not have the capacity to recover gold from difficult to work sulfide ores.
