Phosphate Rock an overview ScienceDirect Topics

Rock phosphate. 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. Many of the mines that produced rock phosphate are closed, and most of the marketed rock
