Know MoreExtraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.
Know MoreJan 16, 2020 · Pyrometallurgy can also be used for gold extraction as well. This can include smelting, in which, the ore is reduced to a molten state as well as drying and roasting, in which other materials in the rock are oxidized to prevent them from hindering the extraction process.

Know MoreGold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.
Know MoreYet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.
Know MoreThe Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
