In order to keep the flowsheet simple, and because of the use of the forced feed type of crusher, we can crush small tonnages up to 100 tons per day with a very simple ...
When low quality ores are processed and the gold price is decreased, many copper–gold plants have to close the CIL circuit and discharge flotation tailings directly to the tailing dams. To recover the gold from flotation tailings, it is important to understand limits of the CIL circuit and then develop an economically viable process.
The cyanidation plant consists of a primary crushing plant, a semi-autogenous grinding circuit, agitation leaching circuit, cyclone wash circuit, gold recovery circuit and carbon regeneration circuit.
