Abstract
Un método de obtener un agente de filtración caracterizado por moler un material que contiene compuesto de magnesio para obtener un tamaño de partículas que pase a través de un tamiz con desde unas 30 a unas 90 mallas; calcinar el material molido a tal temperatura y durante tal tiempo que resulten pérdidas de ignición residuales desde aproximadamente 1 a aproximadamente 8% y moler el material calcinado para obtener un tamaño de partículas que pase desde aproximadamente 93 a aproximadamente 98% del mismo a través de un tamiz de unas 325 mallas.
