- W2941147976 abstract "Elaboration of profitable technology for processing of copper-zinc ores of Madneuli deposit is an important problem for Georgian economics. Typicality of mentioned problems is also lied in the fact that up to 40% of copper-zinc ore is mined and stored on the quarry walls, which hinders the further expansion of the quarry on the mining of main copper ore.Because of t6he complexity of mineral composition of mentioned ore as wellas of the mutual coalescence of valuable components and similarity of the properties of copper and zinc minerals the flotation enrichment if the ores by preparation of the concentrates of separate metals is a very complex task whereas the preparation combined concentrate is possible without the essential losses of main components. The conditions of flotation enrichment of copper-zinc ore of Madneuli deposit were selected and the corresponding concentrate was obtained.The conditions of sulfatizing roasting and leaching of a cinder were determined allowing to exstract 90-95% of Cu; 85-99% of ZnSO4 in the form of corresponding sulfates. The technological scheme of processing of copper-zinc ore with a preparation of the copper vitriol and brass ligature was elaborated. It was established that the exstraction of gold and silver is possible from the residues by thiocarbamide method by high idexes : 95.9% and 82.4%, respectively.As a result of processing of one ton of copper-zinc concentrate the preparation of 343 kg of copper vitriol and of 108 kg of 50 % of brass is possible at transparent extraction of Cu-98%, Zn-92% and 430kg of solid residue containing 7g (16.2g/t) of Au and 9g (20.9g/t) of Ag." @default.
