Leaching Mercury Sulfide Mineral Processing amp; Metallurgy

Leaching Mercury Sulfide. The process parallels cyanidation for the recovery of gold and silver in many ways. The mercury sulfide (cinnabar) is dissolved in a sodium sulfide sodium hydroxide solution and washed from the solids using counter current decantation. The mercury is precipitated from solution using metallic aluminum.
