  • Phosphorus Fertilizer The Original And Commercial Sources

    mar 12, 2018 out of the total rock phosphate resource, the country has a predominance of low grade rock phosphate having only 15.27 million tons reserve of high grade rock phosphate and the remaining low grade rock phosphate is unacceptable to fertilizer industry due to its very low and high caco content the current annual domestic demand of most of the balance is processed, in electric furnaces, into elemental phosphorus which is the main raw material for manufacturing various phosphate compounds (emich, 1984, jasinski, 2007. economic recovery of phosphates is limited to naturally concentrated phosphate mineral deposits. more than countries around the world produce phosphate rock.
