Rock Phosphate Processing Search By MC World. The search for phosphate rock deposits became a global effort in the 20th century as demand for phosphate rock increased. Development of deposits further intensified in the 1950s and 1960s. World production peaked in 1987- 1988 and then again in 2008 at over 160 million metric tons (mmt) of product.

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 ...
