copper mining extraction of gold for electrum

Gold Extraction Recovery Processes. Gold recovery with sluices can vary depending on several factors. Fine gold losses can be minimized by cleaning up more frequently, reducing the speed of the slurry flow to around 0.50 to 0.80 m/s., and decreasing the feed size by performing a previous screening.copper mining extraction of gold for electrum,Gold Separation Process In The Mining ...

GOLD: MINERALOGY AND METAL EXTRACTION -

1983-1-1  This again will be confirmed by the mineralogical studies; Very low Ag to Au ratios, poor correlations between silver and gold, absence of electrum in the polished sections, indicate that the poor recovery is almost certainly due to fine grain sizes; The observation of chemical analyses of the various metallurgical products at this point showing gold enrichments and losses will give a good indication of the host mineral(s): iron-sulphur and gold correlations will indicate a pyrite-gold ...

The treatment of copper–gold ores by ammonium

2002-10-1  The absence of both aeration and cupric ion addition has a positive effect on the thiosulfate stability and results in the case of no cupric ion addition (with aeration), in a gold extraction of 74%. Copper in this composite seems to be unreactive towards ammonium thiosulfate leaching, which confirms the testwork described in Section 5.1 since chalcopyrite, covellite and chalcocite are the copper
