Gold Ore Processing ScienceDirect

The extractive metallurgy of gold ores is largely driven by their grade and mineralogy. The concentration of gold in the Earth''s crust and mantle is extremely low and highly variable, resulting in ore variability in many gold and copper–gold deposits. Gold mining and processing operations are important sources of arsenic release to the
