Method for processing material containing mineral acid consuming carbonate sulfide Minerals and Precious Metals

摘要

The processing of Mineral materials containing Precious Metal with one or more sulfide Minerals and Gangue Minerals which includes different sulfide acid consuming carbonate may include preparing a Concentrate of Sulfur Flotation Flotation or Conditioning Efore the Flotation using a gas comprising carbon dioxide.Flotation can be to a pH without prior acid carbonate decomposition and can be consumed without adding acid for pH adjustment
