A typical arsenical gold ore contains arsenopyrite as the major arsenic mineral. However, some arsenical gold ores, such as those from Nevada in the USA (Getchel deposit), contain realgar and orpiment as the major arsenic-bearing minerals. Pyrite, if present in an arsenical gold ore, may contain some gold as minute inclusions.Extraction of Gold from Refractory Gold-Bearing Ores by,2020-11-12 · In the search for technologies for the extraction of gold from such ores, including those obtained from the Sayak-4 gold deposit, pyrometallurgical processing represents a possible direction.

Extract copper and gold from low-grade ores more efficiently. Ore deposits are becoming increasingly complex to treat and grades continue to deteriorate in known reserves. For instance, approximately 15-20 per cent of the world’s current gold production involves refractory ores that must be pre-treated prior to downstream recovery by cyanidation.Mining production Extraction technology of fine vein ,2015-7-2 · The main valuable ore components are gold and silver. The main part of the gold (80-85%) is in a free form; remaining part is in finely divided form and contained in sulfides (mainly arsenopyrite). The finely divided form of minerals is more suitable for steeply dipping veins (17-18%) than for shallow lode (5-6%). The size of 50-70% of free gold particles is about 0.1 to 1.0 mm. The gold form is lamellar and isometric. The ore
