Abstract:
In an electrolytic cell receptacle for electrowinning or electrorefining of nonferrous metals, the electrolytic cell receptacle having side walls and a bottom extending between the side walls, said bottom and side walls of the electrolytic cell receptacle comprised of a polymer concrete and having substantially planar surfaces defining interior and exterior portions of the electrolytic cell receptacle, wherein at least a portion of the polymer concrete is reinforced with a pre-woven mesh, the electrolytic cell receptacle also having an overflow and draining system, and electrolyte feed system, and a seismic-resistance support system, wherein the improvement comprises:first curved surfaces located on the interior portion of the electrolytic cell receptacle, the first curved surfaces defining intersections between adjacent side walls, each of the first curved surfaces extending upward from the bottom of the electrolytic cell receptacle to an opening of the electrolytic cell receptacle; and the seismic-resistance support system further comprising supports extending outward from the bottom of the exterior portion of the electrolytic cell receptacle, and seismic fuses connected to the supports, the seismic fuses restricting movement of the electrolytic cell receptacle and adapted to break before the side walls and the bottom of the electrolytic cell receptacle when the electrolytic cell receptacle is subjected to seismic forces.
