The chapter discusses the flowsheeting based on unit operations and applied to a mineralogical classification of gold ore types. Whether gold is the primary value metal or a part of a suite of metals, such as nickel, cobalt, copper, or platinum-group metals (PGMs), selection of an appropriate combination of these units would likely result in a …
