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.
Heap leaching of gold ore is to crush low-grade gold ore to a certain size (or granulate) and pile it on a leak-proof bottom mat paved with materials such as asphalt, concrete or plastic cloth, and use low-concentration cyanide, alkaline solution, Solutions such as non-toxic solvents or dilute sulfuric acid are sprayed on the mine pile to dissolve the gold, and the gold-containing …

What is cyanide and why do we need cyanide-free gold leaching process? Cyanide (CN –) has been used since 1889 to recover gold from hard rock. As sodium cyanide (NaCN), it reacts with gold, oxygen (O), and water (H 2 O) to form a gold cyanide complex (Na [Au(CN) 2] ) and sodium hydroxide (NaOH). The chemical reaction dubbed the "Elsner Equation", named …

The major ores of gold contain gold in its native form and are both exogenetic (formed at the Earth's surface) and endogenetic (formed within the Earth). The best-known of the exogenetic ores is alluvial gold.
When the ore is extracted, most of the pieces are smaller than one metre in diameter. The pieces are sorted by the level of gold that they contain. Then, workers crush and grind the rocks at the process plant until they are finer than flour. Finally, the gold is extracted via a chemical reaction using cyanide solution.
