Abstract:
     This invention is a continuation of "patent application No 85100187".All of the component in the low grade calc-phosphorous ore can be efficiently transfered into several products by chemical separation process, which includes of baking by radiation, pulpreaction and regeneration of solution. while phosphor-concentrate is obtained, the side-products of filtrate, NH3 and CO2 are treated by reqeneration. The process is a complete enclosed cycle which is superior to other mineral concentration processes by without producing of three wastes "higher rate of reaction and lower consumption of heat energy.
