Abstract
A process of obtaining powdered sodium silicate from sand tailings generated from iron ore processing addresses the production of raw materials used in the manufacturing of geopolymers to be employed mainly by the construction industry and in road paving. The utilization of this tailing reduces environmental impact generated by the disposal in large dams, as well as enabling addition of value to a tailing by obtaining a commercially applicable product.
