Thus, the proposed two-step process is a promising approach for enhancing the efficiency of gold recovery from sulfide concentrates by means of biooxidation. Acknowledgments This work was supported by the Russian Foundation for Basic Research , grant no. 15-08-03763 a .
Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite Sb2S3 , the antimony Sb
The combined gravity and bulk flotation tests indi ed an 88% recovery from higher grade ores of approximately 5 grams of gold per tonne. This improved gold recovery from higher grade ores is

If a significant portion of gold is fine <300 µm , a high G-Force centrifugal concentrator can be used to improve recovery. Free-Milling Gold. Low Grade In the case of low grade < 1 g/t free-milling gold deposits, the ore is often crushed and heap leached.
To extract precious metals from gold-copper ores and concentrates, the presence of copper minerals has detrimental effects on gold extraction unless high cyanide should be added to keep CN:Cu molar ratio above 4. For every 1% of reactive copper present about

ADVANTAGES DOVE Centrifugal Concentrators are designed with fully integrated and closed circuit, stand alone high pressure/multistage pump, to insure continuous recovery of ultrafine gold with no gap in pressure. DOVE Centrifugal Concentrators are designed with fully integrated feed mechanism and concentrate moisture adjustment mechanism, in order to eliminate freezing condition.
stibnite concentrates. Gold and antimony, locally with minor scheelite, have been mined from over 200 vein structures in the Hillgrove mineral eld, the main part of which forms a northwest
