soil acidity concealer manufacturing process using solid waste generated in the production of precipitated calcium carbonate

摘要

"PROCESS FOR MANUFACTURING SOIL ACIDITY CORRECTIVE USING SOLID WASTE GENERATED IN PRECIPITATED CALCIUM CARBONATE PRODUCTION". The present invention relates to the manufacture of soil acidity concealer with the use of industrial solid waste generated in the precipitated calcium carbonate manufacturing process, in the virgin lime hydration phase, and in the calcination phase being generated two types of residues. industrial types, the first type with fine grain size and the second type with coarse grain size. The industrial solid waste generated in the precipitated calcium carbonate manufacturing process, in the hydration phase of virgin lime, has a chemical constitution, very similar to the acidity correctives of soils called agricultural hydrated lime and calcined limestone. The solid residues generated in the calcination phase have similar chemical characteristics to the lime acidity correction of the calcined soil. The purpose of the present invention is the use of these residues as a soil acidity correction through the processing of the product, drying and adjusting the grinding degree to the specifications demanded by the consumer market.
