Gold cyanidation

In this redox process, oxygen removes, via a two step reaction, one electron from each gold atom to form the complex Au(CN) 2 ion. Application. The ore is comminuted using grinding machinery. Depending on the ore, it is sometimes further concentrated by froth flotation or by centrifugal (gravity) concentration.

Artisanal and Small Scale Gold Mining Without Mercury

Bubbles containing gold and other hydrophilic minerals accumulate at the top of the water level as froth. This froth is then scraped off to create a concentrate of gold and other hydrophilic minerals. Flotation creates high quality concentrates and is good at capturing fine gold. Flotation usually requires a substantial amount of capital investment.
