The Electrolytic Zinc Plant of the Sullivan Mining Company

This paper describes the recently constructed electrolytic zinc plant of the Sullivan Mining Company which is located near Kellogg, Idaho. The first unit which has just been completed has a capacity of 50 tons of slab zinc per day. Provision has been made for two additional units which will bring the capacity up to 150 tons per day. The ``Tainton-Pring'' electrolytic process, which uses strong acid for leaching and high current density for electrolysis, is employed in this plant. The metallurgical process and the physical layout of the plant are briefly described, after which follows a general discussion of the electrical features.
