Abstract

The amounts of large-tonnage mineral waste that are generated raise serious misgivings at environmental protection agencies. Most mineral waste is a valuable secondary raw material, but the lack of integrated technologies for their processing substantially slows down their processing. An assessment was made of the possibility of joint processing of quartz-leucoxene concentrate (waste from oil extraction) and brucite-containing waste from the production of refractories. Joint pyrometallurgical processing of two wastes made it possible to obtain magnesium titanate, a valuable product for different industries. In hydrometallurgical processing of magnesium titanate, a complex magnesium-titanium containing coagulant was obtained, which showed high efficiency in the process of treating high-pH wastewater (concrete mixing unit). In addition to increasing the purification efficiency (reducing the residual concentrations of pollutants), the use of a complex reagent made it possible to reduce reagent costs and intensify the sedimentation and filtration of coagulation sludge (simplification of the instrumentation).

制备复合混凝剂联合处理耐火材料中石英-亮色烯精矿和含水镁石废料

产生的大吨位矿物废物的数量引起了环境保护机构的严重担忧。大多数矿物废料是有价值的二次原料，但由于缺乏综合处理技术，大大减缓了对它们的处理。对石英亮绿精矿(采油废渣)与耐火材料生产中含水镁石废渣联合处理的可能性进行了评价。通过对两种废渣的联合火法处理，可以获得具有不同工业价值的钛酸镁。在湿法冶金处理钛酸镁的过程中，获得了一种含镁钛复合混凝剂，该混凝剂在处理高ph废水(混凝土搅拌装置)中表现出高效率。除了提高净化效率(降低污染物的残留浓度)外，使用复合试剂还可以降低试剂成本，加强混凝污泥的沉淀和过滤(简化仪器)。
