Abstract：Electromagnetic separation technology is a new molten metal purification technology, which is based on the unequal electromagnetic forces exerted on the molten metal and non-metallic inclusions in electromagnetic field due to the difference of their electric conductivities. This paper introduced the state of the art of the electromagnetic separation technology at home and abroad, making a comprehensive analysis and comparison regarding to the traditional molten metal separation technology, the types and features of the common inclusions in molten metals, the principle and classification of the electromagnetic separation technology and the factors affecting the separation efficiency. The future development directions of the electromagnetic separation technology were proposed in the end
