摘要
Abstract
Under the requirement of green sustainable chemical development,the novel technologies for full utilization of phosphate rock were discussed, containing the utilization of main elements resources (phosphorus,calcium,fluorine and silicon,etc.),the recycling of inorganic acid and the adopting coupling process in feed phosphate production. The cyclic utilization of sulfur resources in phosphogypsum,the building cementitious materials produced by calcium in phosphogypsum replacing primary limestone ore, the full utilization of calcium resources in phosphate rock as raw material of feed calcium phosphate product to reduce the consumption of limestone and lime, the whole process recovery technology of fluorine resources in phosphate rock by wet-process phosphoric acid production,the wet-process phosphoric acid technology to produce low silicon phosphogypsum by high silicon phosphate rock and the green sustainable feed phosphate production technologies were investigated in this study.关键词
