Hydrometallurgical Processing of Gold-Containing Ore and its Enrichment Products

摘要: This research focuses on the hydrometallurgical processing of auriferous ores and their products, namely, flotation gravity concentrates. The main valuable component an ore sample any deposit is gold. gold content should be in range 11.11–12.87 g/ton. rock-forming minerals original are quartz (60.1%), quartz–chlorite–micaceous aggregates (3.8%), carbonates (7.1%). In this study, various sizes were treated by direct sorption cyanidation under leaching modes, results obtained presented. was leached with concentrations sodium cyanide (NaCN) solution to study effect complexing agent concentration recovery. Data dynamics revealed that a decrease NaCN from 0.2% 0.03% leads recovery 26.81%. Original could easily processed using methods. coarseness 95% − 0.045 mm averaged 97.77%. work features full studies concentrates tailings, as well effects concentrate resistant intensive (i.e., only 67.07% into solution). use 1% lead nitrate (PbNO3) during reduce refractoriness increase up 94.35%. total 98.71%, tailings averages 96.57%. at size (95.5% 0.074 mm) 96.64%. A 95.5% 0.02 35.43% because strong chemical activation material grinding.
