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

摘要

We describe a rejection process, environmentally safe, hazardous industrial waste contaminated with lead (such as, for example, those generated as discardable by-products in primary and secondary operations of lead smelting in particular slag and matte blast furnaces) of reducing the size of industrial waste contaminated with lead and treat before encapsulating them in a hardenable material, with the zeolite which forms naturally - clinoptilolite - enough to prevent the ions lead (Pb + 2) to flow out of the industrial waste and to be exposed to the action of atmospheric agents (e.g., hot air and rain, or due to freezing and thawing cyclic in climates temperature variation) even over an extended period of time.
