PROCESS FOR FIXING LEAD-CONTAMINATED ECOLOGICALLY HAZARDOUS INDUSTRIAL WASTE MATERIALS USING CLINOPTILOLITE ZEOLITE

摘要

Ecologically safe methods of treating lead-contaminated and hazardous industrial wastes (e.g., those produced as by-products discarded in primary and secondary lead smelting processes, in particular blast furnace solvents and mats) are provided. Lead from industrial waste, even after exposure to prolonged atmospheric action (e.g., as a result of freezing and thawing cycles in hot air, rain, or mild climates) before reducing the size of the used industrial waste and encapsulating it in the cured material. Treating with clinoptilolite, a naturally occurring zeolite in an amount sufficient to prevent leakage of ions (Pb ⁺ ).
