Extracting Gold | HowStuffWorks

­Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers pour off the flux and then the gold.

Cyanide-free gold leaching in exceptionally mild chloride ...

Oct 10, 2019· The oxidation agent was observed to affect gold extraction. In a slightly more concentrated chloride solution (2.8 M) gold extraction was 93–94% when minor cupric (0.1 M and 0.02 M) was used as oxidation agent. In ferric leaching, the gold extraction was slightly lower 85–89% (with ferric concentration of 0.1 M and 0.04 M).
