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.This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. the best practices for chemical leaching are a combination of pre-concentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners mining.

Processing involves transforming rock and ore into a metallic alloy of substantial purity – known as dor – typically containing between 60-90 gold. during its life, a number of factors – such as the price of gold or input costs – will affect which areas of an ore body are deemed profitable economic to mine.
