Due to the requirements of environmental protection, many mines have replaced sodium cyanide with environmentally friendly gold leaching agents.
There are many chemicals used in flotation, including collectors, foaming agents, inhibitors and regulators.
Many of them are combined with several mineral processing methods, such as heavy flotation, flotation and cyanidation.
After cyanide leaching, it is more complicated to adsorb with carbon, then analyze electrolysis and then gold refining.
