  • Publication number: 20220127151
    Abstract: A method and system for producing highly activated silicate material, wherein the 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. A heat source heats reaction materials to a reaction temperature in the presence of a reaction medium. For the hydrothermal reaction process, the reaction medium and heat source are an exhausted steam that is a byproduct of another industrial process. For the HTSR process, the silicate source material and the heat source are a molten slag byproduct from another industrial process.
    Type: Application

  • Patent number: 11242261
    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.
