Treatment of Gold–Telluride Ores - ScienceDirect

Jan 01, 2016  Ultrafine milling of a flotation concentrate followed by cyanidation replaced roasting because of environmental issues. The first application of this approach, at KCGM (Kalgoorlie Consolidated Gold Mines), presented significant challenges in terms of high consumption of cyanide and losses of gold in leach residues.

Since early 2001, Kalgoorlie Consolidated Gold Mines (KCGM) has successfully operated an ultra fine grinding (UFG) circuit to supplement its roaster capacity for the treatment of the refractory gold flotation concentrate. A second UFG mill was installed in 2002 taking the total UFG capacity to over 20tph while grinding to 11-12 microns and achieving over 90% gold recovery.

Treatment of Gold–Telluride Ores - ScienceDirect

Jan 01, 2016  They took a high-grade +20 mm KCGM flotation concentrate and performed a two-stage leach. In the first stage, leaching was carried out using 0.1% NaCN at a pH value of 9.2 for 24 h. It had been suggested that the native gold would be dissolved under these conditions but not the telluride gold.

Using Plain Chute to Recovery Gold from Leaching Residue ...

Based on the analysis of the properties of leaching residue of the gold flotation concentrate, through the application of newly-developed multi-layer automatic plain chute, it is possible to recover natural gold, pyrite and other metallic minerals from the leaching residue of flotation concentrate by using the gravity separation method, which enhanced the index of ore dressing recovery rate.

Feb 06, 2018  Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity. This mixture is placed into a large tank filled with distilled water.
