摘　　要：本文介绍了常用的硫酸回收利用技术及从钛白废酸中回收钛、铁、钪等有价金属的方法,总结了以钛白废酸为原料生产硫酸亚铁净水剂、铁系颜料、普通过磷酸钙及浸出矿石和废渣的技术,最后提出了钛白废酸回收及综合利用的发展方向。This paper introduces the commonly used technology of sulfuric acid recovery and recovery of valuable metals such as titanium, iron and scandium from titanium white waste acid. The technology of producing ferrous sulfate water clarifying agents, iron pigments, ordinary calcium superphosphate and leaching ore and waste residue from waste acid of titanium dioxide is summarize. Finally, the author puts forward the development direction of recovery and comprehensive utilization of waste titanium acid.
