Method of binding heavy metals originating from industrial waste.

摘要

1. The method of binding heavy metals originating from industrial waste consists in binding metals with granulated blast-furnace slag. Unique characteristics: From 10 to 50 percent (by mass) of industrial waste materials is mixed with 50 to 90 percent of granulated blast-furnace slag, or with a mixture of granulated blast-furnace slag with up to 50 percent (by mass) of flue dust. The binding agent is additionally activated with up to 10 percent (by mass) of Na2C03, NaOH or water glass. The mixture is granulated and undergoes the process of infusion or hardening in a pressure chemical reactor.
