It occurs in two basic commercial varieties: GCC — ground from natural rocks, and PCC — precipitated chemically, with a purer composition and a finer, controlled grain.</p> <p>It is one of the most widespread and cheapest mineral raw materials of industry. From the perspective of a bulk-materials terminal, calcium carbonate is a cargo of a dual nature: chemically completely safe (inert, non-toxic, with no ADR classification), yet logistically demanding — because in the form of a fine meal it generates dust and cakes like any very fine mineral powder.</p>
