The process consists of two parts: (1) the production of crude phosphoric ,acid, from wastes such as steelmaking slag; (2) producing high-purity yellow phosphorus by low-temperature carbothermic reduction of phosphoric ,acid, (H3PO4). The details of the carbothermic reduction of phosphoric ,acid, are presented in this paper.

Processing by nitric ,acid, is the most suitable for phosphorus slag leaching. An experimental data was analyzed by using method of “initial rate” – the equation of formal kinetics and criterion-Pilling-Bedford’s (z P-B). It was shown that REMs in the slag is presented by carbonate-apatite Ca 10 [PO 4] 6 CO 3 or rare earth apatite and ...
