Abstract

The article contains data on the content of trace contaminant of cadmium compounds in phosphate ores of volcanic and sedimentary origin. On the basis of the data of laboratory and industrial studies with participation of the authors analyzed distribution of cadmium compounds at the processing apatite concentrate of Kolskii peninsula and Maroc phosphorites. It is shown that the toxic contaminants are mostly extracted with phosphoric acid and contaminates its and products of its further processing. The most advantageous from the toxicology viewpoint is appatite concentrate of Kolskii peninsula that contaminated minimally as compared with the phosphates originated at other birthplaces.
