ally been depleted, and refractory gold ores (RGOs) make up approximately one-third of the total gold production from natural ores [3–4]. Recovery of gold from RGOs may be car-ried out with approximately <50% efficiency on average by direct cyanidation, which requires pretreatment to liberate the locked and preg-robbed gold [5]. Moreover, the ...
Plant design and construction was underway from 2006 till November 2009, when an 8.0 Mtpa facility was commissioned. However, as of 2013 the plant was only treating the ore at a rate of 7.0 Mtpa with gold recoveries of 70%, sometimes lower. According to the site management the failure to meet design was a problem with

Most of the world's gold originates in ore bodies that are mined. Gold ore is generally leached in an alkaline cyanide solution. In many cases the ore needs to be pretreated to facilitate extraction. Pretreatment generally consists of oxidation in an autoclave at elevated temperature and pressure or in a roaster at high temperature.

The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press.
