gold ore draw design with scale

Artisanal and SmallScale Gold Mining Without Mercury Chemical leaching makes use of the chemical properties of gold to leach it from ore, concentrate, or tailings. 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 process design of gold leaching and carboninpulp circuitsa nonrefractory gold ore is shown in Figure 2. Table I and Table II illustrate the capital and operating
