Abstract

EN ESTE PROCEDIMIENTO DE OBTENCION DE CARBONATO CALCICO DE ALTA PUREZA, A PARTIR DE CUALQUIER MINERAL QUE CONTENGA CALCIO SE SOMETE EL MINERAL A UN TRATAMIENTO TERMICO Y A UNA LIXIVIACION CON SOLUCION ACUOSA DE SACAROSA; LA DISOLUCION DE SACARATO CALCICO RESULTANTE DE LA LIXIVIACION CON SOLUCION ACUOSA DE SACAROSA DEL PRODUCTO OBTENIDO EN EL TRATAMIENTO TERMICO DEL MINERAL DE PARTIDA, SE SOMETE A UN PROCESO DE CARBONATACION EN DOS ETAPAS SUCESIVAS, PUDIENDO EN CASO NECESARIO Y EN FUNCION DE MINERAL DE PARTIDA INTERCALARSE ENTRE AMBAS LA FILTRACION DE LA SUSPENSION PRODUCIDA. LA CONCENTRACION DE LA SACAROSA DEBE ESTAR COMPRENDIDA ENTRE 50 GR./L. Y 600 GR./L. DE PREFERENCIA ENTRE 200 Y 300 GR./L. ESTE PROCEDIMIENTO PERMITE OBTENER UN CARBONATO CALCICO DE PUREZA SUPERIOR AL 99% A PARTIR DE MINERALES DE LA MAS VARIADA COMPOSICION EN CUANTO A LOS CONTENIDOS EN CALCIO Y MAGNESIO.
