Abstract:
1. An electrolytic apparatus for use in an oxide electrowinning method, said apparatus comprising: an annular electrolytic vessel made of a metallic material and having an annular space with a bottom formed therein and an upper portion; a high frequency induction coil for heating a substance to be processed in said electrolytic vessel; an annular anode installed at the bottom of the annular space formed in the annular electrolytic vessel; rod-shaped anodes and rod-shaped cathodes installed in the upper portion along the axial direction in the annular space and arranged in parallel, the rod-shaped anodes and the annular anode being arranged vertically; a first electrolysis controller connected between the rod-shaped cathodes and the annular anode, and a second electrolysis controller connected between the rod-shaped cathodes and the rod-shaped anodes, wherein one of a parallel pair of the rod-shaped anodes and the rod-shaped cathodes arranged in parallel or and a vertical pair of the annular anode and the rod-shaped cathodes arranged vertically is used for main electrolysis and the other of the pairs is used for auxiliary electrolysis.
