To date, over 22 million ounces of gold have been produced through this process. Fosterville process selection. Fosterville primary ore is highly refractory generally exhibiting less than 10% cyanide leach extraction after grinding to a size of P 80 = 45 micron. It requires oxidative pre-treatment to release gold from pyrite and arsenopyrite.
To make gold soluble sodium cyanide (NaCN) is added and the cyanide ion forms a complex ion with the gold. This complex ion, [Au(CN)2]-, is readily soluble. Issues of gold extraction using cyanide: Cyanide is toxic to animal and plant life and may cause death if exposed to high enough doses. Free cyanide is cyanide ion (CN-) and hydrogen

NEW YORK: Scientists have developed a new technique which they claim can grow and harvest gold from crop plants. The technique of finding gold called phytomining uses plants to extract particles
Oct 20, 2014· Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

Step Two.Borax is used to separate gold from stones and other non-metal elements. We drill the gold bar to extract a sample for testing to determine the precious metal content.
Cyanide extraction of gold through milling of high-grade ores and heap leaching of low-grade ores requires cycling of millions of liters of alkaline water containing high concentrations of potentially toxic sodium cyanide (NaCN), free cyanide, and metal-cyanide complexes. Some milling operations result in tailings ponds of 150 ha and larger.
There are a host of complex cyanide anions that could be found in cyanide leach solutions, but only the following have been studied: Fe(CN)6³-, Fe(CN)6 4-, Zn(CN)4²-, Ag(CN)2-, Cu(CN)4³-. Percentage extraction versus pH curves were determined for all these metal anions at metal concentrations of 5×10-³ M, i.e., equimolar with 1000 ppm gold.
