The technology used to weathering or more phosphorus-containing ore argillaceous material, this technique is widely used overseas phosphate, phosphate rock surface weathering Dianchi in Yunnan rock and other areas may be employed in this technique, and it can be obtained Good economic benefits.
This technology is to wash the phosphate rock, remove the slime, and then sieve and classify to obtain high-quality phosphate concentrate. Purely a kind of physical beneficiation , the process is simple, it can be produced in the open air, and it does not consume chemicals, so it does not pollute the environment.
This technology is widely used in the development of phosphate rock in Dianchi area of ​​Yunnan. The total scale of large, medium and small phosphate mine scrubbing plants that have been put into operation is more than 30 million tons/year (the largest scale of a single plant is 1 million tons/year). Concentrate P 2 O 5 . The grades are all above 30%, and the MgO content is below 1%. Its economic benefits are among the best in the phosphorus industry.
