Lime is an important ingredient in the manufacture of pulp and paper. It is used in the treatment of liquid wastes as a coagulant in color removal, a filtration conditioner and as a neutralizing agent. It is also used in the recovery of valuable by-products from pulp and paper mill wastes.
Both lime and value-added lime-based products are available from Graymont for use in sulfite-pulping and kraft pulping processes. Graymont can supply quicklime as make up lime and chemical grade calcium carbonate for paper making applications.
