Dec 20 2019 · Obtain mercury sulfide HgS as cinnabar to use for gold extraction Cinnabar is naturally occurring mercury sulfide HgS so you may be able to harvest it If you can’t harvest it purchase it online While the cinnabar is nontoxic it will become toxic during the extraction processFurther Details
Apr 24 2017 · Bleach is the chemical compound sodium hypochlorite When combined with hydrochloric acid the mixture produces chlorine that dissolves gold from gold ore This was the first commercial method used for gold extraction Place the ore into the mortar and grind it to the size of sand grainsFurther Details
Leaching dissolves the gold out of the ore using a chemical solvent The most common solvent is cyanide which must be combined with oxygen in a process known as carboninpulp As the cyanide and oxygen react chemically gold in the pulp dissolves When workers introduce small carbon grains to the tank the gold adheres to the carbonFurther Details
