Abstract
Procedimiento de fabricacion de partículas de carbonato de calcio y/o carbonato de calcio y de magnesio, en el cual se trata un medio acuoso de pH básico yque contiene Ca(OH)2 y/o Ca(OH)2-Mg(OH)2 mediante iyenccion del CO2 gaseoso para formar carbonato de calcio y/o carbonato de calcio y de magnesio, y en elcual se recuperan las partículas de carbonato formadas, efectuándose el tratamiento del medio acuoso en presencia de por lo menos un aditivo elegido del grupoconstituido por hidracina, hidroxilamina, sales solubles de hidroxilamina y sus mezclas. Partículas de carbonato de calcio y/o carbonato de calcio y demagnesio así obtenidas.Process for manufacturing particles of calcium carbonate and / or calcium and magnesium carbonate, in which an aqueous medium of basic pH is treated and containing Ca (OH) 2 and / or Ca (OH) 2-Mg (OH) 2 by means of CO2 gas gaseous to form calcium carbonate and / or calcium and magnesium carbonate, and in which the carbonate particles formed are recovered, the treatment of the aqueous medium being carried out in the presence of at least one additive chosen from the group constituted by Hydrazine, hydroxylamine, soluble hydroxylamine salts and mixtures thereof. Calcium carbonate and / or calcium and demagnesium carbonate particles thus obtained.
