    • 摘要: 以江西某钨矿山合格矿为研究对象,研究了超声波对白钨浮选过程的强化作用及对尾水沉降速率的影响.研究结果表明,在相同的浮选条件,超声波处理后,矿浆温度有所上升,浮选速度加快,有利于白钨浮选.与自然沉降相比,超声波一定程度上可加快尾水的沉降速率.

    • 摘要: 白钨选矿行业由于使用大量水玻璃,水玻璃的分散、抑制作用,尾矿水难以澄清,使选矿药剂难以降解.尾矿水中含有的选钨药剂使白钨的回收率降低.目前白钨选矿企业回水只用于末端的选钨,特别是国家对环保要求越来越严格,回水利用率远低于国家标准的要求,对环保造成严重的压力.本研究结果表明,电凝聚对白钨选矿中产生的废水处理效果显著;白钨选矿废水加石灰在尾矿库沉淀后,水不调pH,一次电凝聚处理,对硅酸盐的去除率仅为19.3%,加上二次电凝聚处理对硅酸盐的总去除率仅为52.8%;白钨选矿废水调pH至9.5后,一次电凝聚处理,对硅酸盐的去除率高达89.2%以上,加上二次电凝聚处理,对硅酸盐的总去除率高达98.1%以上.

    • 摘要: 河南某白钨尾矿中萤石含量占25%左右,是亟待回收的矿产资源.尾矿中碳酸钙含量在45%以上,属典型的高钙型萤石.尾矿中萤石在白钨加温精选过程的高温条件下受到大量水玻璃的强烈作用,可浮性变差.试验表明,碳酸钙的可浮性明显好于萤石.本研究采用碳酸钙优先浮选—再萤石浮选试验流程,以降低浮选流程中碳酸钙含量和提高萤石浮选粗精矿品位,为萤石精选提供有利条件.闭路流程试验结果表明:碳酸钙优先浮选,可以预先脱除72.44%的碳酸钙,萤石损失率仅为12.98%;最终得到含萤石91.88%,含碳酸钙4.32%,回收率为46.07%的萤石精矿.实现了该钨矿山企业的矿产资源的综合回收目标.%The fluorite content in a scheelite tailings in Henan accounts for about 25 %. The content of calcium carbonate in the tailings is more than 45 %, which is a typical high calcium fluorite. The scheelite floatability became lower after the fluorite was strongly affected by a large amount of water glass under the heated conditions. The test shows that the floatability of calcium carbonate was better than that of fluorite. The flowsheet of Calcium carbonate preferred flotation-fluorite flotation was applied to reduce the content of calcium carbonate and improve the grade of fluorite flotation coarse concentrate. The closed circuit test results show that calcium carbonate can be pre- remove by 72.44 % with fluorite loss rate reaching only 12.98 %. Fluorite concentrate containing 91.88 %fluorite, 4.32%calcium carbonate was obtained, with recovery attaining up to 46.07%. The goal of comprehensive recovery of mineral resources in the tungsten mine is realized.

    • 摘要: The wastewater out of scheelite's heated precession has the characteristics of high concentration of silicate ions, strong basicity and difficult sediment. After the natural sedimentation of tailings ,the residual silicate ions in the recycle water have negative effect on the scheelite roughing recovery. This paper studied the effects of common waste water treatment agent and acid on the removal rate of the silicate ion. The results show that the silicate ion removal rate reaches 93.6 % with the sulfuric acid dosage of 6 g/L. The water after treating is colorless and transparent. Industrial test results show the silicate ion removal rate was 56.20 % with a sulfuric acid dosage of 845.5 g/t in December 2015. The field roughing index was stable. The recovery rate increased by 18.21 % and 5.39 %respectively compared with the same period in the previous two years ,realizing the comprehensive utilization of mineral processing wastewater.%白钨加温精选废水存在硅酸根离子浓度高、碱性强、沉降难等特点,尾矿废水经尾矿库自然沉降后,回水中仍残留大量的硅酸根离子,对白钨矿粗选回收率造成很大的影响.本文研究了常用废水处理药剂以及酸对硅酸根离子去除率的影响,结果表明硫酸对硅酸根离子的去除效果最好,当硫酸用量为6g/L时,硅酸根离子的去除率达到93.6%,上清液呈无色透明;工业试验结果表明:2015年12月份硫酸用量为845.5 g/t时,回水中硅酸根离子的去除率为56.20%,现场白钨矿粗选指标稳定,粗选回收率比前两年同期分别提高18.21%和5.39%,实现了选矿废水的综合利用.

    • 摘要: 综述白钨与含钙脉石浮选分离抑制剂的研究进展.无机抑制剂在白钨浮选中应用广泛,其抑制机理研究较多,机理解释相对统一,而高分子有机抑制剂具有较强的抑制能力,较好的选择性,但抑制机理暂不明确.因此开发具有特效作用的小分子和高分子抑制剂,查明起选择性抑制作用的关键基团及其作用机理,对白钨与含钙脉石浮选分离有重要意义.%Research development of the depressants for flotation separation of scheelite and calcium-bearing gangue are reviewed.Inorganic depressants are widely used in scheelite flotation, of which the mechanism has been well studied with a uniform explanation.Polymer organic depressants possess strong inhibiting ability and high selectivity.However, the inhibitory mechanism of polymer organic has not been fully revealed.Thus, developing small molecules and polymer organic depressants with special effects, and studying the action mechanism of organic depressants are significant for the flotation separation of scheelite and calcium-bearing gangue.
