Processing of refractory gold ores - ScienceDirect

The Mereur ore as well as containing Processing of refractory gold ores 1033 carbon has a significant carbonate content and this allows the process to be operated in the alkaline pH range. First Miss Gold Inc. Getchell project achieved commercial production during 1989.

Roasting and Refractory Gold Ore - Manhattan Gold and Silver

Gold’s resistance to oxidation is a critical point of most refining and extraction methods and the roasting process is no exception. During roasting refractory gold ore is treated with extremely hot air. This causes the sulfites to oxidize separate from the ore and become sulfur dioxide.

Refractory Gold Mining SGS

Refractory Gold SGS has earned the reputation as the world’s leading gold metallurgical testing facility. Our decades of experience have allowed us to assemble the most comprehensive assortment of expertise and equipment to address refractory gold issues. The problems that result from refractory gold are caused by:

Lowering the Threshold for Refractory Gold Deposits with N.

Processing refractory ore involves the addition of flotation coated biooxidation and neutralization unit operations. The coated biooxidation process is shown in greater detail in Figure 3. Here a sulfide gold concentrate is coated onto support rocks.
