The equipment needed for the gold concentrate zinc powder replacement process includes:
Autoclave: An autoclave is used to treat the gold concentrate with acid and high temperature to remove impurities and prepare it for the zinc powder replacement process.
Filter press: After the autoclave treatment, the gold concentrate slurry is filtered using a filter press to remove solid impurities.
Leaching tank: The gold concentrate slurry is then transferred to a leaching tank for the zinc powder replacement process.
Zinc powder feeder: Zinc powder feeder is used to add zinc powder to the leaching tank.
Agitation tank: Agitation tank is used to mix the gold concentrate slurry and the zinc powder together to facilitate the chemical reaction.
Vacuum filter: After the zinc powder replacement process is complete, the gold powder is separated from the solution using a vacuum filter.
Electrolytic cell: The gold powder obtained after vacuum filtration is dissolved in aqua regia, and the gold ions are then reduced to metallic gold by electrolysis in an electrolytic cell.
Smelting furnace: The metallic gold obtained after electrolysis is melted in a smelting furnace to obtain gold ingots.
In addition to these main equipment, other equipment such as pumps, pipes, valves, and control systems are also necessary for the gold concentrate zinc powder replacement process.
