methods of production of calcium carbonate from limestone

How Calcium Carbonate is

Japanese Limestone. Limestone is the raw material for precipitated calcium carbonate. Limestone is the only mineral resource in which Japan is completely self-sufficient 1). Japan mines the third largest amount of limestone in the world after the United States and China2). About 3% of the limestone mined in Japan is exported.
