How To Mercury Gold Mining Process Flow Chart
Gold processing Gold processing Refining Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine.Jun 01, 2018 A comprehensive investigation of Hg flows in the whole gold production process was carried out to identify the Hg emission points and to understand the Hg emission characteristics of LGSP. Hg input to LSGP was mainly from gold concentrates, and the dominant Hg output byproducts were waste acid, sulfuric acid, cyanide leaching residue and air.
