The solubility of gold in a water and cyanide solution was known by 1783 (Scheele), by Bagration in 1843 and Elsner in 1846 who recognized the necessity of oxygen in the process, (a method of exctraction by chlorination (Plattner) considered during 1848 proved uneconomical) this prior to the discovery of an economical method of treatment with potassium cyanide by J.S. MacArthur (with R. and, or, W. Forrest).
For example, inorganic reagents (such as potassium carbonate in a Williamson ether synthesis) are ignored as they are not incorporated into the final product.
There have been many suggestions to what this might be, the sarcolemmal ATP-sensitive potassium channel, the mitochondrial ATP-sensitive potassium channel, the mitochondrial permeability transition pore, reactive oxygen species generation, chloride channels, the inward rectifier potassium ion channel and connexon 43 related channels.
