The Bulyanhulu rougher flotation circuit performance has been determined by establishing the performance of individual cells. Direct sampling was done on all the rougher cellinput, output and size analysis was performed on the samples with material in each sizefraction assayed for copper and gold to determine their recoveries. It was observed that …

201465 · In order to overcome the difficulty of extracting gold from gold-bearing sulfide ore by cyanide process, flotation was adopted based on mineralogical analysis. Mineralogy shows that gold particles are of superfine structure and mainly enclosed by sulfide ores. Primary gold-bearing sulfide ore is fine-grained pyrite and arsenopyrite.

2021929 · The aim of this study is to diagnose and optimize a closed multistage gold ore flotation circuit in an operational industrial plant. Linear circuit analysis (LCA), a partition-based model, and a mass balance model using flotation first-order kinetics are employed to diagnose the current process. The result shows that the current circuit operates with high …

20191215 · A combination of HPGR technology coupled with high-intensity cyanidation (Pyke et al. 2006) was used to recover coarse gold from the quartzitic ore processed by Bendigo Mining. The flow sheet also entailed flotation of auriferous sulfides that were subjected to high-intensity cyanidation.

200191 · Abstract Native gold and electrum are naturally-occurring alloys containing gold and silver and a little copper. They are the most common and important forms of gold in ores. Their recovery by gravity concentration, cyanidation, or flotation from ores, typically containing 0.1–20 g/t Au is of great commercial importance. This paper reviews the …
