Most of the mineral waste is a valuable secondary raw material, but the lack of integrated technologies for their processing significantly slows down their processing. As part of the work, an assessment was made of the possibility of joint processing of quartz-leucoxene concentrate (waste from the oil production process) and brucite-containing waste from the production of refractories. Joint pyrometallurgical processing of two waste products made it possible to obtain magnesium titanium, a valuable product for various industries. Hydrometallurgical processing of magnesium titanate made it possible to obtain a complex magnesium-titanium-containing coagulant, which showed extremely high efficiency in the process of treating wastewater with a high pH level (concrete mixing unit). The use of a complex reagent, in addition to increasing the cleaning efficiency (reducing residual concentrations of pollutants), made it possible to reduce reagent costs and intensify the processes of sedimentation and filtration of coagulation sludge (simplification of the instrumental scheme).","PeriodicalId":445802,"journal":{"name":"Steklo i Keramika","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139365828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
