Gold processing Britannica
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 recoverable by leaching, is recycled back to a pyrometallurgical process.
