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.

 · They were engaging in just this process. If gold is physically bound to minerals, it can sometimes be separated by the appliion of heat in a smelting operation. At other times, the only way to separate the gold is to immerse quantities of black sand in chemical baths – a process called wet chemical extraction. The more complex the separation process, the higher the cost becomes of ...
