  • CO2 Energy Reactor – Integrated Mineral Carbonation: Perspectives on Lab-Scale Investigation and Products Valorization

    Frontiers Energy Res., 15 February 2016

    CO2 Energy Reactor – Integrated Mineral Carbonation: Perspectives on Lab-Scale Investigation and Products Valorization

    To overcome the challenges of mineral CO2 sequestration, Innovation Concepts B.V. is developing a unique proprietary gravity pressure vessel (GPV) reactor technology and has focussed on generating reaction products of high economic value. The GPV provides intense process conditions through hydrostatic pressurization and heat exchange integration that harvests exothermic…

    CO2 Energy Reactor – Integrated Mineral Carbonation: Perspectives on Lab-Scale Investigation and Products Valorization

    To overcome the challenges of mineral CO2 sequestration, Innovation Concepts B.V. is developing a unique proprietary gravity pressure vessel (GPV) reactor technology and has focussed on generating reaction products of high economic value. The GPV provides intense process conditions through hydrostatic pressurization and heat exchange integration that harvests exothermic reaction energy, thereby reducing energy demand of conventional reactor designs, in addition to offering other benefits. In this paper, a perspective on the status of this technology and outlook for the future is provided.

  • Nickel Extraction from Olivine: Effect of Carbonation Pre-Treatment

    Metals

    In this work, we explore a novel mineral processing approach using carbon dioxide to promote mineral alterations that lead to improved extractability of nickel from olivine ((Mg,Fe)2SiO4). The precept is that by altering the morphology and the mineralogy of the ore via mineral carbonation, the comminution requirements and the acid consumption during hydrometallurgical processing can be reduced. Furthermore, carbonation pre-treatment can lead to mineral liberation and concentration of metals in…

    In this work, we explore a novel mineral processing approach using carbon dioxide to promote mineral alterations that lead to improved extractability of nickel from olivine ((Mg,Fe)2SiO4). The precept is that by altering the morphology and the mineralogy of the ore via mineral carbonation, the comminution requirements and the acid consumption during hydrometallurgical processing can be reduced. Furthermore, carbonation pre-treatment can lead to mineral liberation and concentration of metals in physically separable phases. In a first processing step, olivine is fully carbonated at high CO2 partial pressures (35 bar) and optimal temperature (200 °C) with the addition of pH buffering agents. This leads to a powdery product containing high carbonate content. The main products of the carbonation reaction include quasi-amorphous colloidal silica, chromium-rich metallic particles, and ferro-magnesite ((Mg1−x,Fex)CO3). Carbonated olivine was subsequently leached using an array of inorganic and organic acids to test their leaching efficiency. Compared to leaching from untreated olivine, the percentage of nickel extracted from carbonated olivine by acid leaching was significantly increased. It is anticipated that the mineral carbonation pre-treatment approach may also be applicable to other ultrabasic and lateritic ores.

  • METHOD FOR CONVERTING METAL COMPRISING SILICATE MINERALS INTO SILICON COMPOUNDS AND METAL COMPOUNDS

    Toegekend EU EP20110726216 20110608

    Method for converting metallic silicate minerals to silicon compounds and metal compounds via a conversion reaction, characterized in that the conversion reaction is performed in a gravity pressure vessel (GPV), wherein: the GPV comprises two channels having separate entries on the upper side of the GPV and which channels are mutually connected on the bottom of the GPV, and wherein a dispersion of solid particles of the silicate minerals in water is carried into the GPV in a descending flow…

    Method for converting metallic silicate minerals to silicon compounds and metal compounds via a conversion reaction, characterized in that the conversion reaction is performed in a gravity pressure vessel (GPV), wherein: the GPV comprises two channels having separate entries on the upper side of the GPV and which channels are mutually connected on the bottom of the GPV, and wherein a dispersion of solid particles of the silicate minerals in water is carried into the GPV in a descending flow, one or more reactants for the conversion reaction are added to the dispersion, and the silicon compounds and metal compounds formed during the conversion reaction are carried away via an ascending flow of the GPV. The method provides a method for sequestration of carbon dioxide, wherein the heat produced can be utilized to form a concentrated gas flow of carbon dioxide prior to sequestration.
