Phosphate Rock - an overview ScienceDirect Topics
Rock phosphate is a naturally occurring ore of marine sedimentary origin. It may have a composition of 0-30-0, but the grade is noted as 0-3-0, since rock phosphate is sparingly soluble and little of the phosphorus is available to crops. ... Wet-process sulfuric acid acidulation is the most common technique for treating phosphate rock ...
