Process Flowsheet Selection

The role of competitive fluid-rock interaction processes in the formation of high-grade gold deposits. Ore quality relates to the ore grade or tenor that may be present in a given ore body but also commonly translates directly into the recovery efficiency of the metallurgical process. In the case of gold deposits, the gold ore may be classified ...
