Abstract
Methods and systems for producing activated silicate materials are disclosed. A silicate source material is provided for reaction with a reforming agent in a reforming process. The reforming process is a hydrothermal process and/or a high temperature silicate reforming (HTSR) process. The reaction materials are brought to the suitable reaction temperature via a heat source in the presence of the suitable reaction medium. The activated silicate materials exhibit improved reactivity compared to non-activated silicate materials and thus are advantageously employed in elemental extraction processes to produce a valuable material product.
Claims6
A method of producing an activated silicate material comprising:
- providing a silicate source material;
- reforming the silicate source material to the activated silicate material with a reforming agent in a reforming reaction;
- and providing the activated silicate material to an elemental extraction process,
- wherein the reforming the silicate source material is performed using a high temperature silicate reforming (HTSR) process at about 300° C. to about 1500° C., wherein a weight ratio of the silicate source material to the reforming agent is about 0.1:1 to about 100:1, wherein the silicate source material comprises slag, mine tailing, fly ash, kiln dust, serpentine, olivine, wollastonite or a combination thereof.
