Claim:
1. A method for large scale industrial production of pure nano calcium powder from raw materials including 3-7 parts pearl, 8-12 parts mother of pearl, 2-3 parts red coral, 20-30 parts oyster shells, 35-55 parts clam shell, 5-10 parts giant clam, 1-3 parts pangolin shell, and 3-7 parts ore, where ore is defined as limestone, cold water stone, and goose pipe rock in the weight ratio of 1.5:1.5:1.0 comprising the following steps, applied separately to each of said raw materials: A. sand-blasting each selected raw material to remove dirt and other contaminants from the surface of the raw material; B. grinding each cleaned raw material into small particles of 200-400 microns; C. heating said particles from step B to a decomposition temperature in inert gas; D. then grinding said particles, after heat decomposition, to a size of 30-50 microns; E. nanometer lapping the resulting particles until the particle size is reduced to about one nanometer; then F. mixing all the particles from step E for each raw material, to obtain the final pure nano calcium product.
