After the gold ore has been removed from the earth using mining equipment, it is sent to a gold processing plant. The typical gold processing plant begins with a cone crusher, to reduce the particle size of the ore. Next, it is loaded on a conveyor belt, where an overbelt magnet removes tramp metal from the gold mining process.

The processes in which gold cyanide is adsorbed on activated carbon are very robust mechnically and very efficient metallurgically. CIP and CIL circuits are tolerant of plant upsets, changes in feed composition and "less-than-optimal" plant designs. As a result, owners and operators may not realize that their plant

The current state of world mineral resources is characterized by a decrease in the quality of minerals. An increase in production and processing volumes is possible only through the development of new deposits and the involvement of off-balance ores, dumps and tailings, slags and other industrial wastes in the integrated mining process.
