Webforming ores had a relatively fine microwave-absorbent phase grain size that was sparsely disseminated. Batchelor (2013) reviewed published literature from the pre-vious 20 years detailing experiments using high and low power density microwave treatments on metalliferous ores investigat-ing reduced ore competency. The vast majority of the papers WebExperiments with biomass and iron ore packed beds placed separately were carried out in the interval between 200 and 1000 °C in an infrared furnace. Iron ore reduction was observed at low temperatures (< 800 °C) and increased up to 1000 °C, where wustite, metallic iron and cementite were detected by XRD. Carbon deposition at low …
