Abstract:
     This new technology utilizes the primary phosphoric acid extracted from sulfuric acid and phosphate ore pulp to decompose further the phosphate ore and increase the yield of phosphoric acid and to increase the phosphate granules in pulp. It will enhance the wash down of scales on the concentrator and decrease the consumption of sulfuric acid (it will save 0.15-0.25 ton industrial concentrated sulfuric acid per ton ammonium phosphate produced) and lower the prodn. cost. It will also increase the trace elements in the product and improve the soil quality.
