In this study,a sodium silicate base depressant,a BD depressant and a benzyl hydroxamic acid base collector are adopted to process heat flotation tailings in Shizhuyuan plant.
采用以水玻璃为主的组合抑制剂，ＢＤ单─抑制剂和以苯甲羟肟酸为主的混合捕收剂，处理柿竹园多金属矿白钨加温精选尾矿，品位含ＷＯ３为１。
Benzylhydroximic acid,screened out under the guidance of principle of iso- merism,is an effective collector for fine wolframite.
在同分异构原理指导下筛选出的苯甲羟肟酸是细粒黑钨矿的有效捕收剂，与组合抑制剂ＡＤ配合使用，可使细粒黑钨矿与萤石、方解石等含钙矿物有效分离。
