free circulation of the leaching agent. The leaching period is 2 – 4 days and gold recovery lies in the order of 70 – 80%. The cheapest but slowest technique is heap leaching. It is a process usually applied to low grade gold ore
Then treating leaching liquid by the activated carbon or metal zinc method and the barren solution returns to heap leaching operation for reuse. Ore Treatment The ore is crushed into fine particles 30-50mm by using jaw crusher or cone crusher then will be heap leaching directly; or pelletization fine particles are pelletized into bigger lumps then piled by forklift.
