Summary: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).
