Process of obtaining powdered sodium silicate from sandy tailings originated from the iron ore concentration process, use of the sodium silicate, and sodium silicate
PROCESS OF OBTAINING POWDERED SODIUM SILICATE FROM SANDY TAILINGS ORIGINATED FROM THE IRON ORE CONCENTRATION PROCESS, USE OF THE SODIUM SILICATE, AND SODIUM SILICATE The present invention relates to a process of obtaining powdered sodium silicate from sandy tailings from iron ore processing, as well as to the sodium silicate thus obtained and the use thereof. The present invention mainly addresses the production of raw materials used in the manufacturing of geopolymers to be employed mainly by the construction industry. The utilization of this tailing reduces environmental impact generated by the disposal in large geotechnical structures (piles and dams), as well as enabling addition of value to a tailing by obtaining a product with commercial application.
