Abstract The principal gold minerals that affect the processing of gold ores are native gold electrum Au Ag tellurides aurostibite maldonite and auricupride In addition submicroscopic solid solution gold principally in arsenopyrite and pyrite is also important The main causes of refractory gold ores are submicroscopic gold the Au Ag tellurides and very fine grained gold <10 µm locked in sulfides

Leaching Fine Gold Mineral Processing Metallurgy

in the majority of instances the product of all sliming contains from 5% to 35% of sand that will not pass a 200 sieve moreover a good proportion of the sand —200 sieve is perfectly leachable if properly freed from slime as has been already explained so it is fairly safe to say that of the usual all slime pulp from 30% to 50% does not …

Gold extraction Wikipedia

A refractory gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold A refractory ore generally contains sulphide minerals organic carbon or both
