What is Cyanidation Gold Extraction Process?-xinhai

Cyanidation has a history of more than 200 years since it was applied to gold and silver ore extraction in 1887. At present, cyanidation is still one of the main gold extraction process due to its high recovery rate, high adaptability to ore and local production.. Generally, cyanidation methods can be divided into two categories: agitation cyanidation and percolation cyanidation.
