Process of gold cyanidation and zinc powder washing and gold extraction

The process of gold cyanidation, zinc powder cleaning and gold extraction is a method of cyanide leaching-zinc powder replacement-washing-electrolytic gold extraction, which is used to extract gold from gold-bearing ores. The process includes the following steps:

Cyanide leaching: add gold-bearing ore to a cyanide agent (such as sodium hydroxide) to leach the gold.

Zinc powder replacement: replace the gold in the cyanide leaching solution with zinc powder to form gold mud.

Washing: Wash the gold mud with water to remove impurities.

Electrolytic gold extraction: the washed gold mud is placed in an electrolytic cell, and the gold is extracted by electrolysis.

The key steps of the process are cyanide leaching and zinc powder replacement, in which the cyanide agent can replace gold from the ore to form gold mud. The gold mud is then washed with water to remove impurities. Finally, the gold mud is placed in an electrolytic cell, and the gold in it is extracted by electrolysis. In this way, the purpose of extracting gold from gold-bearing ores can be achieved.
