Phosphate Rock Calcination

Strategy for Boosting Rock Phosphate Efficiency and ...

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
