Precipitated Calcium Carbonate lumps, also referred to as PCC lumps, are produced when calcium hydroxide (lime) reacts with carbon dioxide. It generally is available in crystalline structure but can also be processed into a fine powder. The factory-produced calcium carbonate is pure with low levels of impurities. The whiteness and brightness of precipitated calcium carbonate lumps are unmatched. It is because of these properties, that lumps are highly demanded and used in paper, paint, cosmetics, rubber, and several other industries. Their main purposes in all these industries are fillers and additives
