PROCESS FOR OBTAINING AN ASBESTOS-FIBER MATERIAL OF A HIGH DEGREE OF SEPARATION

摘要

A colloidal solution of Chrysotile asbestos which is obtained from a pre-purified aqueous suspension of crude Chrysotile asbestos by means of a shearing action is subjected to filtration or centrifuging to eliminate therefrom incompletely separated colloidal matter. Subsequently, the asbestos is precipitated from the refined solution and subjected to further processing.
