 · Gold is a precious metal and also a chemical element with atomic number 79. When not mixed with other metals it is reddish yellow, heavy, soft, easy to work with, and conducts electricity readily. Gold is part of a group of metals called noble metals, which include gold, silver, and platinum; they all resist chemical action, do not corrode, and are not easily changed by acids.

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.
