摘要:
广西大厂矿区选厂在生产中采用摇床重选的方法对锡石进行回收，存在锡石难选、细泥损失大等问题。为强化尾矿中细粒级锡石的回收，提高锡选别作业的回收率，对该选厂摇床重选得到的尾矿开展了锡石细泥回收浮选实验研究。实验结果表明，通过“预先脱硫-锡石浮选”工艺流程，在条件实验的基础上，确定采用2 000 g/t捕收剂，800 g/t活化剂和6 g/t具有消泡功能的辅助捕收剂药剂制度进行浮锡实验，最终重选尾矿选锡闭路实验得到锡品位为7.41%，回收率47.61%的锡精矿，指标良好，经济可行。
Abstract:The concentrator of Dachang mining area in Guangxi adopts the method of shaking table gravity separation to recover cassiterite in production, which has problems such as difficult cassiterite separation and large loss of fine mud. In order to strengthen the recovery of fine-grained cassiterite in tailings, the flotation test of cassiterite fine mud recovery was carried out on the tailings obtained from the shaking table gravity separation of the concentrator. The test results show that through the technological process of flotation “pre-desulfurization and cassiterite flotation”, on the basis of conditional tests, 2 000 g/t collector, 800 g/t activator and 6 g/t defoamer were used for the tin flotation test. The tin concentrate with a tin grade of 7.41% and a recovery rate of 47.61% was obtained in the closed-circuit test, and the index is good and economical.
