WASTE ASBESTOS RECOVERY FROM PRODUCTION OF ASBESTOS PRODUCTS

摘要

WASTE ASBESTOS RECOVERY FROM PRODUCTION OF ASBESTOS PRODUCTS Waste asbestos generated from a production process utilizing a surfactant as the dispersant and a coagulant as a solidifying agent is recovered for reprocessing by treating the waste with an inorganic acid to react with the precipitated surfactant and solubilize the precipitating ions. The precipitating ions are removed by washing. The insoluble residue, containing asbestos and the surfactant is mixed and reacted with an alkali to form a dispersion of asbestos that may be reprocessed by conventional methods.
