Antimony Mobilization through Two Contrasting Gold Ore ...
Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines. The Reefton gold mine was originally developed in gold-bearing quartz veins; Sb concentrations were low (<100 mg/kg) compared to arsenic (As ...

Donlin Gold Receives Updated Feasibility Study | E & MJ
The gold-bearing sulphides will be recovered by flotation to produce a concentrate representing 17% of the mass with an average gold grade of 12.7 g/mt. The concentrate is refractory and will be treated in an autoclave prior to cyanidation. Overall gold recovery from flotation, pressure oxidation and carbon-in-leach is estimated at 89.8%.

Gold Ore - an overview | ScienceDirect Topics
The most common pretreatment processes for refractory sulfide ores include high-temperature roasting, pressure oxidation, chlorination, and the more recent bacterial oxidation of sulfides. Conventional abiotic pretreatment processes are not advantageous due to high capital and operating costs, inefficient gold recovery, and environmental pollution.
