Experimental Study on Zinc Recovery from a High-Zinc Sulfide Concentrate in Guangxi
摘要
Abstract
Aiming at the technical challenge that the zinc content in the sulfur concentrate obtained after flotation for zinc recovery in a Guangxi zinc mine is significantly higher than the requirement of≤0.6％for the total lead+zinc content in qualified sulfur concentrates,experimental research was carried out to recover zinc from the sulfur concentrate.Lime was used to adjust the pulp pH to 11～11.5 for the selective depression of pyrite;copper sulfate was added to activate sphalerite;butyl xanthate and ammonium dibutyl dithiophosphate were mixed at a mass ratio of 5:1 as a high-efficiency combined collector;and a closed-circuit flotation flowsheet of"one roughing,two scavenging,and three cleanings"was adopted.A zinc concentrate with a grade of 37.49％Zn and a recovery of 72.98％was obtained,along with a qualified sulfur concentrate containing 41.67％S,52.13％Fe,and 0.41％Zn.关键词
