During roasting, refractory gold ore is treated with extremely hot air. This causes the sulfites to oxidize, separate from the ore, and become sulfur dioxide. Once all of the sulfides are oxidized, the remaining gold ore can be processed normally. The roasting method has been around for hundreds of years. Prior to the 20th century, the process ...
copper-gold ores (higher copper than gold values) the process route is typically flotation and smelting. In the latter case, gold credits are obtained from smelting the copper concentrates and if gold reports to the flotation tailings, they may also require cyanidation which can prove problematic with cyanide soluble copper.

The initial phase of gold mining relied heavily on simple, manual tools. During the Gold Rush era in the mid-19th century, prospectors used pans and sluice boxes to sift through riverbeds and stream sediments. The pan, a simple yet effective tool, allowed miners to separate gold from other sediments using water, a technique known as panning.
