The Mining Process OceanaGold

Gold at Macraes is known as refractory ore which means it is ultra fine and resistant to the typical cyanide leach process typical of most gold processing plants This refractory nature of the ore led to inefficiencies recovering the gold from ore in the past The ore now goes through a three stage processing cycle to ensure the gold is economically recovered from the ore

Metates Chesapeake Gold Corp

28/06/2021· The concentrate is transported downhill to the processing site via a slurry pipeline where the sulfides are oxidized in an autoclave circuit prior to cyanidation to recover the gold and silver Payable gold and silver production in the first six years of full production years 2 7 averaged 845 000 ounces gold and 25 million ounces silver per year Total cash cost per gold equivalent ounce for

Arsenic Precipitation from Solutions in Autoclave

Currently the share of gold extracted from technologically simple gold ores is steadily decreasing which determines the involvement in the processing of refractory gold ores containing finely disseminated gold and silver in sulfides mainly in pyrites and arsenopyrites Autoclave oxidation is a promising method of pretreatment of the refractory sulfide arsenic gold bearing raw materials

Deportment of gold in an autoclave pressure

The gold deportment data show that % of the gold losses in the CIL residue are related to sub microscopic gold contained in the unoxidized pyrite mineral phase Figure 1 The carbonaceous matter present in the ore exhibits strong preg robbing capacity and contributes to % of the gold losses in the form of surface gold Figure 1
