Abstract
This work presents the results of geological-mineralogical and physico-chemical characteristics of a sample from the deposit Andesite Finger of the open pit South Mining District in the Copper Mine Majdanpek. According to the mineralogical composition of valuable metals, the mineralization is composed of chalcopyrite, magnetite, pyrite and molybdenite. Copper contents of the deposit increase of 0.1% in the border of gneiss and schist to andesites, ranging up to 0.5% in the silicified andesites and gneissgranites. Approximate molybdenum content ranges from 10 to 100 ppm depending on the position and depth at which it is located. Geological reserves of copper in the deposit South Mining District amount: 463,127,844 t of ore, medium copper content in the ore 0.316%, i.e. the amount of Cu 1,465,556 t, medium gold content in the ore 0.178 g /t, i.e. the amount of 82,156 t Au, medium silver content in the ore 1.365 g/t, i.e. the amount of 632,274 t Ag. Based on technological characteristics of formed ore sample, it is necessary to carry out further testing of collective and selective flotation in order to obtain the optimum technological parameters of the flotation process and higher recovery of all usable components.
