Cyanide Chemistry & Gold Extraction
The results of these studies, made on a large variety of ores, was to show in all cases a partial extraction of gold. This extraction varied from 20 per cent, to 95 per cent. While it was always easy to make a partial extraction of the gold, it proved difficult, and in many cases impossible, to get anything like a complete extraction.

Gold extraction - Wikipedia
Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets …
Extraction of gold using cyanide - NZQA
Extraction 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.
Chemical and Physical Properties of Gold
The gold ion in the +1 oxidation state (Au(I) +) is called the aurous ion. The gold ion in the +3 oxidation state (Au(III) 3+) is called the auric ion. Compounds containing gold in the -1 oxidation state are called aurides. (Cesium and rubidium can form auride compounds) Gold is one of the noble metals.
Gold cyanidation - Wikipedia
Gold cyanidation is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide …
