Abstract

1. Perfeccionamientos en la extracción de sílice de soluciones de sales de magnesio, en la recuperación de una sal de magnesio soluble en agua, a partir de una mezcla de reacción que contiene una sal de magnesio soluble en agua, sílice y otras impurezas de sales metálicas, habiendo sido obtenida dicha mezcla de reacción por la reacción en cantidades estequiométricas de una mezcla pastosa y acuosa de residuos de asbesto con un ácido mineral, caracterizados por comprender el añadir un exceso de los residuos de asbesto a dicha mezcla de reacción, siendo la cantidad de los residuos de asbesto así agregada de al menos un 5% en peso de la cantidad estequiométricas inicial de los residuos de asbesto hechas reaccionar con el ácido mineral y recuperar la solución de la sal de magnesio mediante filtración.
