摘要：
Four P-bearing raw material were extracted with H2SO4 in two industrial plants differing in the number of reactors. The effect of the raw materials used on the efficiency of the H3PO4 extraction process was studied. The properties of the obtained extractive H3PO4 and waste phosphogypsum were characterized. Recommendations for the decompn. of a specific P-bearing raw material in an appropriate technological line were developed.
