Ammonia-Autoclave Processing Of Low-Sulfur Collective Concentrate from Udocan Deposit

Abstract

 The complexity of mixed sulfide-oxidized ore industrial processing from the copper sandstones of the Udokan deposit is primarily due to the lack of selective extraction and processing of various types of ores actual possibility. The use of flotation-hydrometallurgical technology, including the separation of collective copper concentrate with its subsequent atmospheric sulfuric acid leaching, is associated with the distribution of copper between two products - sulfide copper concentrate and cathode copper, as well as with the inability to obtain silver concentrate.
