| Korea has considerable deposits of zinc bearing complex sulfide ore, especially marmatite among others, but no processing plant, either pyrometallurgical or hydrometaillurgical, has been constructed yet. For the processing of the ore, which would contribute a great deal for the Korea metallurgical industry, the basic data on the technological chracteristics of the ore should be established. In order to obtain the basic data for the hydrometallurgical treatment of the ore and the subsequent electrolytic recovery of pure zinc, investigations are under way in expectation of the prospective application for the commercial production. In this article, a brief description of the processes of leaching, purification and electrolysis for zinc production is presented along with a few experimental results. |
