Abstract (en)
[origin: EP0431313A1] A container in which minerals such as copper are purified in an electrolytic process includes bottom (12), end (15, 16) and side walls (13, 14) for containing a corrosive electrolyte, such as, a sulphuric or hydrochloric acid solution. The bottom, end and side walls of the container are composed of a cured mixture of 10-19 percent of a modified, vinylester or polyester thermo-setting resin and the balance consisting of aggregate. The surfaces of the container are coated with a resin layer having a backing layer consisting of about 70%-80% resin and 20%-30% a reinforcement which may comprise a fiber glass mat of non-continuous strands 1/2"-2" long or a light cloth of fiber glass or other synthetic fiber. An overflow box (20) is integrally formed in a first formation extending vertically along one end wall of the cell and an overflow pipe (21) is molded into the first formation and extends from the overflow box outwardly of the cell. A vertical covered inlet channel (30) or cast-in pipe is provided at the opposite end of the container and extends from its upper to its lower end.
