硫磷钛联产法钛白粉清洁生产技术典型案例龙蟒集团自主创新以低品位磷矿和高钙镁钛精矿为原料,应用“硫-磷-钛”联产法钛白粉清洁生产工艺,在工业化规模上实现废酸、酸性废水、硫酸亚铁的全面循环综合利用。该工艺通过将硫化工、磷化工和钛化工进行产业整合,硫化工生产的硫酸和副产蒸汽供给钛化工和磷化工使用,钛化工所副产的废酸、酸性废水又供给磷化工进行磷矿预
Production of Titanium Dioxide, Titanium Dioxide and Titanium Dioxide, a Typical Case of Clean Production Longmao Group, with its independent innovation, uses low-grade phosphate rock and high calcium magnesium titano-concentrates as raw materials and uses “sulfur-phosphorus-titanium” cogeneration titanium dioxide cleaner production Technology, in the industrial scale to achieve waste acid, acid wastewater, ferrous sulfate comprehensive recycling comprehensive utilization. The process through the sulfur chemical industry, phosphorus chemical and titanium chemical industry integration, sulfuric acid and sulfuric acid production by-product steam supply to the titanium chemical and phosphorus chemical industry, titanium chemical by-product of waste acid, acid waste water and phosphorus chemical industry to supply phosphorus Pre-mine
