Roasting and Refractory Gold Ore

Roasting and Refractory Gold Ore

+

16/07/2014 · 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. Once all of the sulfides are oxidized, the remaining gold ore can be processed .

Gold recovery: Effect of ozonation on refractory gold ores ...

+

Mineral processing of refractory gold ore is uneconomical through conventional processing methods. The ore recovery is normally below 80% due to sulphide encapsulated gold and result into high reagent consumption by carbonates. This study was conducted to investigate the use of ozone to the existing pretreatment processes to increase the gold recoveries. To achieve this, ozone gas was bubbled ...

Gold Process Mineralogy

Gold Process Mineralogy

+

during the processing of a gold ore, periodic mineralogical analyses of ore feed and mill products are needed to determine the nature of the problem if the gold recovery is lower than expected. Therefore, a routine process mineralogical study of gold ores normally includes some or all of the following objectives:1 • Determine gold and silver grade by fire assay and analyze .

About Mining

About Mining

+

We use alternative gold recovery methods in some processing plants to accommodate different ore characteristics or other requirements. For example, ore that has a high level of sulfide minerals or carbon (or both) is called refractory ore. Refractory ore resists normal processing methods as the high sulfide minerals trap gold particles, making it difficult for the cyanide to reach the gold .
