Total 67 rock phosphate samples collected from 36 phosphate deposits and 30 phosphate fertilizer samples from main phosphate plants of China were studied.The content of Cd in rock phosphates from different deposits varied from 0.1 to 571 mg/kg, with an average value of 15.3±74 mg/kg. The highist value was found in the rock phosphates from Guangxi Province, varying from 12.2 to 571 mg/kg; while the lowest Cd content of the rock phosphates from Hubei Province varied from less than 1 to 2.10 mg/kg. Fortunarely. all the phosphate deposits of high Cd content are of less importance in the phosphate fertilizer production of China. If not counting these minor important but high Cd content phophase rocks the average Cd content of phosphate rocks of China should be 0.98 mg/kg.
