Abstract
The article discusses the possibility of a new method for processing tin-containing raw materials using a renewable carbon source - rice husks. A review of the literature on this topic showed the absence of publications on the possibility of using unconventional reducing agents in tin metallurgy. The work is devoted to filling the gap in the study of the possibility of using rice husks as a reducing agent in tin metallurgy. The process of pyrolysis of rice husks and reduction of tin oxide using rice husks were compared with traditional reducing agents, coal and coke. Heating was carried out in an inert atmosphere (argon). Thermal effects were studied using thermogravimetric analysis and differential scanning calorimetry. The optimal heating rate (5 °C/min) with the maximum decomposition of rice husks (up to 82 %) was found experimentally. It was found that the reduction of SnO2 with coal and rice hulls begins already at = 800 °C, while interaction with coke does not occur even at 900 °C and above. Rice husks have been proven a promising reductant for SnO2.
