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 arebination of pre concentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners, and high gold recoveries. First, concentration
Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value.

Gold, recognizable by its yellowish cast, is one of the oldest metals used by humans. As far back as the Neolithic period, humans have collected gold from stream beds, and the actual mining of gold can be traced as far back as 3500 B.C. , when early Egyptians the Sumerian culture of Mesopotamia used mined gold to craft elaborate jewelry, religious artifacts, and utensils such as goblets.
