The process of obtaining extractive phosphoric acid with using mixtures of apatite concentrate and Mazydag phosphorite, sulfuric and wasted phosphoric acids has been investigated. It is established that usage of the new raw material for the production of extractive phosphoric acid allows to increase the degree of substitution of the expensive deficit apatite concentrate for the Mazydag phosphorite up to 45%, and to expand the raw material base of the phosphoric acid production. The process is economically and ecologically expedient.
