Abstract

The concentration plant of Erdenet Mining Corporation (Mongolia) has been successfully exploiting the two-stage scheme of concentration of copper-molybdenum ores during 30 years. This scheme includes three consecutive stages: bulk cycle, finishing cycle and molybdenum cycle. Considering the manufacturing reconstruction process, one of landmark components is the formation of technological schemes with the following substantiation of the scheme of apparatuses` series. The task for the operating manufactures became more complex, because of the necessity of adaptation of the developed scheme of apparatuses` series to the existing production spaces. For example, the schemes of apparatuses` series are considerably rigid structures, created for the specific type of supplied raw materials. At the same time, increasing of productivity of existing enterprises foreordains the involving of ores, supplied from various parts of ore body, into the synchronous processing. These ores differ by the content of mineral resources, ratio of primary and secondary minerals, oxidation level, slags content, etc. All these factors provide the creation reasonability of schemes with increased technological flexibility, which makes possible rather efficient responding on the changing of properties of the delivered raw materials.
