Abstract:

China′s wet process has the characteristics of high industrial concentration and perfect wet process phosphorus in-dustrial system.Some key common technologies are at the international advanced level.However,there are some problems in China′s wet process phosphorus processing,such as the acceleration of phosphorus resource depletion,the sharp reduction of recoverable resources,the excess capacity of phosphate fertilizer,the low utilization rate of phosphate fertilizer and the prominent environmental problems.In view of these problems,it is proposed the suggestions and measures for sustainable development,such as China′s wet process phosphorus industry should accelerate the integration of water and fertilizer technology; build a green cycle development model; form unconventional low-grade phosphate rock wet process technology,realize the source of phosphorous nearly zero emissions;accelerate the research and development of high silicon mixed type rubber phosphate rock utilization technology;form the industrialization technology of reducing times and half oxides;and break through the high-end industrial chain technology package.

Key words: wet process phosphorus processing, phosphate rock, phosphate fertilizer, sustainable
