Gold Recovery 101 - Sepro Systems

Free-Milling Gold Gold ore is considered free-milling when over 90% of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm. Some examples of free-milling gold ores include quartz-veined deposits and oxidized ores.

When the molten mixture has reached more than 1,000°C the metal and slag are tipped into an ingot mould. The slag hardens into glass, leaving the gold ingot of 300 to 500 ounces in the bottom of the mould. These gold bars, known as doré, are about 60% to 80% pure gold, with the rest consisting mainly of silver.
