Gold Extraction Chemical Equation

Gold Extraction Chemical Equation

In precipitating the gold by zinc, the proportion required is about seven times that indicated by the equation Zn 2 Au 2 Au Zn , the discrepancy being due to solution of part of the zinc in the cyanide solution, with evolution of hydrogen.

    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.
