- W2382659547 abstract "An associated gold lead-zinc sulfide ore from Yunnan has extremely complicated intergrowth relationship among valuable minerals and different minerals wrapped corrosively,which makes them hard to be enriched in the process of flotation. According to the special texture and characteristics of ores, the flowsheet consisting of bulk flotation of gold,lead and sulfur minerals,the separation between gold-lead and sulfer-arsenic,and zinc flotation was developed. SA(a high efficient activator for gold minerals) and a combined collector containing DA-1,butylxanthate and ethlxanthate were employed as the collector. Then the separation of gold and arsenic was conducted under high alkalinity using calcium oxide. When the raw ore containing 4.2 g/t Au,1.09% Pb and 0.42% Zn,the concentrates of Au-Pb bulk concentrate grading157.29 g/t Au and 55.84% Pb, the S-As bulk concentrate grading 33.58 g/t Au and zinc concentrate grading 44.01% Zn were obtained, and the recovery of gold, lead and zinc was 90.03%, 86.58% and80.65% respectively,so good result was achieved. These studies could provide valuable reference for the treatment of the same type ores." @default.
