Calcium oxide, calcium hydroxide, and precipitated calcium carbonate (PCC) have a diverse range of functionality in the paper industry. Quicklime and hydrated lime are used in both pulp and PCC manufacturing applications. Calcium carbonates are used in both paper coating and as a paper filler. Calcium oxide or calcium hydroxide is required as a raw material for the PCC manufacturing process. The lime is also a key component of the sulfate process in pulp plants where it is used to recausticize a waste calcium carbonate solution and regenerate sodium hydroxide for reuse in the process. 

Mississippi Lime Company has merchant PCC facilities located at our Ste. Genevieve site. Precipitated calcium carbonates are also manufactured in satellite facilities that are on-site or next to a paper making facility. 

Mississippi Lime’s Standard Quicklime and Standard Hydrated Lime are widely used in both pulp and PCC manufacturing applications.
