Problems of Udokansky Field ores processing
Various pyrometallurgical and hydrometallurgical schemes considered early for processing of the Udokansky field ores are economically inefficient. Heap leaching for processing of all oxidized and low-grade ores is considered in this article. High-grade and good dressable ores are offered to process by traditional pyrometallurgical scheme. The pyrometallurgical scheme allows to produce moreover copper sulfuric acid and vapor, which are necessary for heap leaching realizing. Joint piro-and hydrometallurgical scheme allows to considerably increase complex using of raw materials, as well as process economy.
