An improved electro-refining plate and system which uses the same, in which each electro-refining plate has an edge protector covering the edge of the plate which is exposed to the mineral solution. The edge protector is non-conducting and is secured to the plate using heat and pressure to fuse the edge protector to itself through a series of holes positioned along the edge of the plate. In the preferred embodiment, the edge protector is composed of a ultra-high molecular weight polyethylene. Some embodiments of the invention also use rubber gaskets between the edge protector and the plate; still other embodiments employ an adhesive in conjunction with the fusing action.
