While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.
The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction. Thus, the bulk of the gold may be recovered by leaching techniques using cyanidation or aqueous chlorination, and the residue may then be .

Excellent for fine gold recovery from clay bound ores. It is a continuous slurry feed concentrator and "batches" the concentrate during the run process. It is a continuous slurry feed concentrator and "batches" the concentrate during the run process.
At the end of the leach the loaded carbon is removed from the slurry and the adsorbed gold is stripped out at high temperature and pressure with sodium hydroxide and cyanide solutions to form a high value electrolyte solution. Gold bullion is then recovered from the electrolyte by electrowinning.
The mercury attracted particles of silver and gold. When heated, the mercury evaporated, leaving pure gold and silver.
