Process for producing a calcium carbonate finely divided calcium carbonate rich by-product industry

摘要

From the calcium carbonate enriched secondary product of the nitro phosphorus acid fertilizer plant, the appropriateness it is the process which is easy to the environment in order to form the calcium carbonate which is separated finely in industrial application, this, refinement process, pulverization and the fatty acid of heat treatment or depends on doing the coating which uses the emulsion of that derivative. In one aspect, this invention in order to refine the calcium carbonate enriched by-product which is formed at the time of industrial processing, offers the process in order to form the calcium carbonate where high value is finely divided especially, in the nitro phosphorus acid fertilizer plant.
