PURPOSE: A process is provided wherein coral limestones are ionized which includes rare minerals and calcium to the certain extent to produce ionization mineral calcium. CONSTITUTION: The process comprises: (1) Making a general fireproof kiln, putting roastrolls all layers inside the kiln and spreading coke above the rolls; (2) Laying the crushed coral limestones at the proper size whereupon and burning the coke; (3) Keeping combustion temperature at 700-900°C and continuing burning for 48 hours; (4) Cooling and obtaining light krinka of coral limestones through selection work; (5) Mixing the krinka with activated carbon wherein rice skin and rice straw are blended to heat them for 30 hours at 700-900°C, cooling and obtaining krinka through selection; (6) and Washing, drying to produce white light krinka and grinding it to obtain soluble ionization calcium using fine powder machine.
