阐述云南磷矿浮选与磷化工发展现状,介绍用氟硅酸生产无水氟化氢副产水玻璃、硫酸低温位热能用于磷矿加热浮选以及硫酸与磷酸生产中的废酸用于磷矿浮选介质调整剂等方面的矿化共生耦合技术,提出磷矿浮选与磷化工耦合技术在设备和工艺参数等方面存在的问题,旨在降低磷矿浮选与磷化工成本,实现可持续发展。
The present situation of the development of phosphate rock flotation and phosphorus chemical industry in Yunnan is introduced. The production of anhydrous hydrogen fluoride by-product water glass by fluorosilicic acid is introduced. The low temperature latent heat of sulfuric acid is used for the flotation of phosphate rock and the waste acid in sulfuric acid and phosphoric acid production. Flotation media regulator and other aspects of mineralization symbiotic coupling technology proposed phosphate rock flotation and phosphorus chemical coupling equipment and process parameters in the aspects of the existing problems in order to reduce the cost of phosphate rock flotation and phosphorus chemical and sustainable development of.
