Solar thermal treatment of manganese ores can potentially lower energy costs and reduce greenhouse gas emissions. The solar thermal treatment of three manganese ores resulted in thermal decomposition and reduction of the ores. Empirical results compared to thermodynamic equilibrium models and numerical heat transfer models informs the next steps towards proving the concept. The study provides information regarding the bulk thermal conductivity of manganese ores as determined by optimization of the heat transfer model parameters. Changes observed in the mass of the solar treated samples confirm thermal decomposition and reduction of manganese and iron minerals.
