How Is Gold Extracted From Gold Ore? Sciencing

Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold per ton of rock. In all methods of gold ore refining, the ore is usually washed and filtered at the mine, then sent to the mill. At the mill, the ore is ground into smaller particles with water, then ground again

Extracting Gold HowStuffWorks

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 carbon-in-pulp. 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 carbon.

how do you extract gold from its ore using cyanide

how do you extract gold from its ore using cyanide cyanide process or cyanidation, method for extracting gold from its ore. The ore is first finely ground and may be concentrated by flotation; if it contains certain impurities, it may be roasted. It is then mixed with a dilute solution of sodium cyanide (or potassium or calcium cyanide) while

To extract gold from its ore, the ore is treated with

To extract gold from its ore, the ore is treated with sodium cyanide solution in the presence of oxygen and water. 4 Au(s) + 8 NaCN(aq) + O2(g) + 2 H2O(l) 4 NaAu(CN)2(aq) + 4 NaOH(aq) (a) Determine the mass of gold that can be extracted if 29.3 g sodium cyanide is used.

What is Gold Extraction? (with pictures) wiseGEEK

2020-12-7  Various mineral processing methods are used, often in conjunction with one another, to extract the ore from its rock encasement. Comminution, hydrometallurgy, and pyrometallurgy are used to extract the gold. Comminution is often one of the first steps in gold extraction. Extractors break apart the hard rock containing the ore.

How to Use Bleach on Gold Ore to Remove Gold

Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
