PROCESS FOR OBTAINING SODIUM SILICATE POWDER FROM SANDY TAILINGS FROM THE PROCESS OF CONCENTRATING IRON ORE

摘要

The present invention relates to a process for obtaining sodium silicate powder from sandy tailings from iron ore processing processes. The present invention is intended mainly for the production of raw material used for manufacturing geopolymers for use mainly in the building industry and for paving roads. Recycling said waste decreases the environmental impact caused by disposal thereof in large waste piles and makes it possible to add value to said waste by producing a product of commercial use.
