摘要/Abstract

摘要： 四川某钒钛磁铁矿预富集精矿TiO₂品位为12.142%。针对预富集精矿中钛资源回收利用的问题，采用脱硫—粗选试验进行药剂制度优化，确定了硫酸、氢氧化钠为 pH调整剂，硝酸铅+苯甲羟肟酸为组合捕收剂，水玻璃为抑制剂，在条件试验的基础上，经脱硫—1粗4精1扫钛浮选的闭路流程选别，可获得 TiO₂品位 46.38%、浮选作业回收率为 64.63% 的钛精矿产品，浮选尾矿 TiO₂品位为 4.86%，实现了钛资源的综合回收利用。

Abstract: The grade of TiO2 in the pre-enriched concentrate of a vanadium-titanium magnetite in Si‐ chuan was 12.142%. Aiming at the problem of recovery and utilization of titanium resources in pre-concen‐ trated concentrate，the reagent system was optimized by desulfurization-roughing flotation test. It was deter‐ mined that sulfuric acid and sodium hydroxide were used as pH regulators，lead nitrate + benzohydroxamic acid was used as combined collector，and sodium silicate was used as inhibitor. On the basis of condition test，the titanium concentrate product with TiO2 grade of 46.38% and flotation recovery of 64.63% was ob‐ tained by closed-circuit process of desulfurization one roughing，four cleaning and one scavenging titanium flotation. The TiO2 grade of flotation tailings was 4.86%. The comprehensive recycling of titanium resources is realized.
