9 Step Process for Discovering, Mining & Refining Gold. By ProvidentMetals on January 23, 2012 Filed Under: Uncategorized. We've no doubt all seen the old western movies of the prospector with a pan in the river searching for gold. In early America, pioneers sunk their fortunes into searching for gold this way.

How Is Gold Extracted From Gold Ore? | Sciencing
Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press.

What is Sulfide Mining? | Mining Action Group
Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water, environment, and communities. Why Is Sulfide Mining

How to Purify Gold | Sciencing
Dr. F. B. Miller of the Sidney Mint created a process to purify gold using chlorine, which forms chlorides with silver and other ore impurities but leaves gold unaffected. The refiner places the ore in clay pots, heats the vessels in a furnace and pumps chlorine gas into each pot. After cooking for a few hours, the refiner retrieves the pots and skims off the molten chlorides, leaving behind

Heap leaching - Wikipedia
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the

Processing of Nickel Laterite Ores on the Rise
Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry.

Nickel: smelting, producing-Metalpedia
In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt and
