There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code. Gold refining

Gold as Money. Gold does not dissipate into the atmosphere, it does not burst into flames, and it does not poison or irradiate the holder. It is rare enough to make it difficult to overproduce and malleable to mint into coins, bars, and bricks. Civilizations have consistently used gold as a material of value.
It is not used much anymore, because most leaching is heap leaching, carried out in the outdoors, where drip emitters or sprays distribute the cyanide solution to a large structure of gold ore, called a "heap". And while the pile of ore is called a heap, it is not a haphazard pile of rocks.
Gold recovery costs. Extracting gold from ore can be complicated and countless mines have failed because they did not recover enough gold to balance input costs. The most commonly used process to extract gold is cyanide leaching, based on a chemical reaction first identified in 1894 by L. Elsner.
Perhaps, one of the greatest challenges in the gold mining industry is to produce high grade concentrates consistently at maximum recovery from the mineralized deposit. To quantify recovery is a reasonable idea of the initial ore required to have an economical operation. In this part, a reliable sampling representing the ore is a key aspect.
The Extraction Process. Once the ore has been liberated from the ground, the gold will need to be extracted. The processing consists of taking the big pieces of ore and making them smaller, until ...
