Investigation of Copper Ores Processing Products

Abstract

In recent years, the world technics and technologies development in mineral beneficiation has shown significant achievements in the field of mineral separation basic phenomena and regularities. This allows for creation of highly efficient processes and technologies for processing of primary ore with a complex composition, thus providing the metallurgical industry with necessary high-quality concentrates. As well known, the concentrates produced by beneficiation plants are subject to certain requirements for content of valuable components and harmful impurities. In order concentrates to be a commodity product, they must contain valuable components more than minimum permissible content, and harmful impurities must be a lower content than the maximum permissible. The presentation that is summarized in this article focuses on the results of laboratory experimental studies conducted to characterize copper, pyrite and molybdenum concentrates obtained from sulphide copper ores processing. This study also explored copper and pyrite concentrates from sulphide-oxide copper ores and oxide ores productive solutions. Data from concentrates chemical and particle size analysis are presented. Moreover, а brief description of technological studies conducted, their aims, concentrates and productive solutions obtained are presented. All copper concentrates contain gold and silver, as accompanying valuable components. Harmful impurities other than carbon in the molybdenum concentrate have not been detected. We summarize that all copper products are suitable for copper concentrates market.
