As high grade deposits of phosphate rock are being depleted day by day in the world, future sources will be derived from low grade rocks containing various impurities. Low grade phosphate rocks are not suitable for direct use in acidulation plants unless their tricalcium phosphate (TCP) content is increased to 70% or more, using conventional …
