Read online. Cordierite ceramics was synthesized using a composition prepared by the mixture of three different materials: waste serpentine mine tailing (WST), waste kaolin mine tailing (WKT) and alumina. The formation of cordierite was achieved with the solid-state sintering reactions at 1350ºC for 3 h.

Abstract. Carbon dioxide (CO 2) capture and sequestration includes a portfolio of technologies that can potentially sequester billions of tonnes of CO 2 per year. Mineral carbonation (MC) is emerging as a potential CCS technology solution to sequester CO 2 from smaller/medium emitters, where geological sequestration is not a viable option. In …
