Resource Potential of Stale Flotation Tails of Copper-Oxygen Ores with and Possibe Gold and Silver Extraction

摘要

The article analyzes the possibility and efficiency of processing the stale tailings of flotation plants of the copper-pyrite complex. The resource potential, material composition and technological and logical possibilities of processing a number of technogenic objects are considered. The interrelation and influence of mineralogical and technological factors on the choice of tailings processing technology has been analyzed. Based on complex studies, the stale tails refer to the hard-to-disintegrate form of the geothermal resources due to the high pyrite content and low content of gold and silver present in the "persistent" minerals. The paper analyses the influence of the main factors affecting the formation of the elemental composition of tailings: mineralogical, technological and ecological. The heterogeneous morphometric and mineral composition of sulphide aggregates, their difficult opening and high dispersity characterize the stale tails as hard-flocked raw materials. Concluding, it is impossible to extract gold and silver from this resource using traditional technologies and it is necessary to open precious metals thoroughly by chemical processing.
