Hard Rock Mining Gold and Silver Ore and …
The gold and silver bearing liquid, called pregnant solution, is separated from the ore by various drainage and filtration processes. The most common methods to remove the gold and silver involve activated carbon, or zinc precipitation. The carbon method requires an additional step where the metals are removed from the carbon. The result of both methods is a finely divided black metal powder of gold and silver. The impure mix of gold …

A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by …
Processing, smelting and refining gold | World …
With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ...
Processing technologies for gold-telluride ores
The first modern treatment of gold-telluride ores was performed in 1891 in the Cripple Creek goldfield near the Rocky Mountains in Colorado. Kalgoorlie, in Western Australia, had the honor of being the second major goldfield, and tellurides were successfully processed to ex- tract gold.
