described. The concentrate only represents a certain proportion of the total gold in the sample, and therefore, a diagnostic leach test is done on the gravity tailings in order to obtain a full picture of the gold deportment. CRUSHING AND MILLING Most gold ores should be milled to at least 50–80% passing 75 µm for effective gold

The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
