The slag agent (CaO–SiO 2 –CaCl 2) was added to MG-Si refined slag for the separation and purification of silicon. In this process, the ratio of slag to silicon was 1:1, so that a large amount of slag agent was needed. Meanwhile, the smelting process for silicon recovery from the slag incurs high energy consumption.
