Ultra Fine Grinding Mill Gold Ore

Ultrafine Grinding - an overview ScienceDirect Topics

Ultrafine grinding is used to liberate gold finely disseminated in metallic sulfides. KCGM is the first gold mine using ultrafine grinding followed by cyanidation (Ellis and Gao, 2002). The gold sulfide concentrate is grind with an IsaMill to a P 80 of 10–12 μm.

Large horizontal sand mill for gold ore ultra fine grinding

24/07/2020  The main equipment used in ultra-fine grinding of gold ore is large flow horizontal sand mill, which integrates grinding and classification, and can grind gold flotation concentrate from 74um to 5-20um. After grinding, the gold concentrate pulp can be further oxidized and cyanidated, and the gold recovery can be increased from 30-40% to more than 90%.

Gold extraction - Wikipedia

A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic ...
