Gold processing - Refining Britannica

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 treated by smelting to recover the balance. Generally, scrap with a gold content of less than 0.1 percent, unless readily ...
