Ecofriendly gold dressing agent is a hightech product for gold extraction which can 100 replace sodium cyanide without changing the original leaching process and equipmentTherefore gold dressing agents are commonly used in many gold cyanidation plants all over the world But before using the environmental gold dressing agent it is necessary to do these 10 tests
The process design of gold leaching and carboninpulp assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carboninpulp circuit cip the reagent and utilities operating costs
