摘要
对锑品位20.66%和金品位98.95 g/t的俄罗斯某金锑精矿进行了浮选分离试验研究。结果表明,采用抑硫浮锑工艺,在磨矿细度-0.045 mm粒级占86%时,采用硫化钠和活性炭脱药处理,以硫酸调整矿浆pH值至酸性,加入高效硫抑制剂BK526、活化剂硝酸铅、捕收剂丁铵黑药,获得了锑品位51.56%、锑回收率86.06%的锑精矿和金品位108.35 g/t、金回收率71.20%、锑品位4.41%的金精矿,实现了辉锑矿和载金黄铁矿的高效分离。
An experimental study on flotation separation was conducted for a gold-antimony concentrate with grade of Sb and Au at 20.66%and 98.95 g/t,respectively,from Russia.In an experiment on antimony floatation while suppressing sulfur by adding efficient sulfur depressant of BK526,activator of lead nitrate,and collector of ammonium dibutyl dithiophosphate,the gold-antimony concentrate was ground to a fineness of-0.045 mm 86%,sodium sulfide and activated carbon was added to remove reagent and sulfuric acid was used to adjust the pulp pH to be acidic.Finally,it produced an antimony concentrate grading 51.56% Sb at 86.06% recovery,and a gold concentrate grading 108.35 g/t Au and 4.41%Sb,with gold recovery of 71.20%.It is shown that stibnite and gold-bearing pyrite can be efficiently separated.
