南乌拉尔矿床(麦若泽尔、乌泽利金等)铜矿物类型的矿石中,存在大量含砷的以砷黝铜矿形式为主的黝铜矿。近年来,所研究的麦若泽尔矿床砷黝铜矿矿样含As 0.34～0.8％、矿床矿样含As 0.77～0.95％,乌泽利金矿床含As 0.66％,而乌拉尔的大多数矿床含As则少于0.3％。在麦若泽尔矿床个别区段中砷黝铜矿的铜含量占矿石中总铜量的50％。经测定,黝铜矿矿石中的铜化合物呈原生铜状态,它们不溶于氰化物,且含有很高的黄铜矿量。然而,按着物理化学性质和可浮性,砷黝铜矿和黄铜矿是不
In the ores of the South Urals deposit (Melrose, Uzzelijin, etc.), there are a large number of tetrahedrite containing arsenic and tetrahedrite in the minerals of the copper mineral type. In recent years, the mineral deposits of arsenite, which are studied in the Meiroweer deposit, contain 0.34 to 0.8% As, 0.77 to 0.95% As and 0.66% Asuzeli gold deposits, while most of the Urals deposit Less than 0.3% with As. The copper content of arsenic tetrahedrite accounts for 50% of the total copper content in the individual sections of the Meirowere deposit. It has been determined that the copper compounds in the tetrahedrite ore are in the native copper state, which are insoluble in cyanide and contain a high amount of chalcopyrite. However, according to physicochemical properties and flotability, arsenic tetrahedrite and chalcopyrite are not
