    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

    Present investigation aimed to convert rock phosphate ore into nano zeolite using calcination (from 200 to 700 C) for 48 hrs. and zeolitization (replacement by a zeolite mineral) processes in order to boost rock phosphate ore efficiency as a source of P 2 O 5 even under high soil pHs. Crystallization, phases, physico-chemical characteristics and surface morphology were studied
