Most large sulfate plants recover about 90-98 percent of the lime by dewatering the waste calcium carbonate mud, then calcining it in rotary kilns. Sulfite Process Sulfite plants use quicklime to prepare calcium bisulfite, an acid cooking liquor used to digest or dissolve the non-cellulosic constituents of wood chips (paper and pulp stock).
refining and precipitated calcium carbonate production. High-calcium limes are derived from limestone that contain 0 to 5 percent by weight of magnesium oxide, and thus have a proportionally high calcium content.
include installations for the production of lime in rotary kilns or other furnaces with a production capacity exceeding 50 t per day and industrial plants for the production of pulp, paper and board with a production capacity exceeding 20 t per day .
Lime kiln dust is a very fine material having unique chemical properties of limestone and lime along with silicates and other inert materials, which make the lime kiln dust highly suitable in agricultural uses. Depending on the concentration calcium carbonate it has obtained from lime-material, lime kiln dust can be effectively used in soil- process.
