Iron oxide copper-gold (IOCG) deposits (Hitzman et al., 1992) are a diverse family of mineral deposits characterised by the following features: (1) Cu with or without Au, as economic metals, (2) hydrothermal ore styles and strong structural controls, (3) abundant magnetite and/or hematite, (4) Fe oxides with Fe/Ti greater than those in most igneous rocks, and (5) no clear spatial associations with igneous intrusions as, for example, displayed by porphyry and skarn ore …

Iron Oxide Copper Gold Deposits Processing Methods. Iron oxide-copper-gold iocg deposits, defined primarily by their elevated magnetite andor hematite contents, constitute a broad, ill-defined clan related to a variety of tectono-magmatic settings.The youngest and, therefore, most readily understandable iocg belt is located in the coastal cordillera of northern chile and southern peru, where it is part of a volcano …

Special Issue Information. Dear Colleagues, The discovery of the Olympic Dam, and its definition as a new type of copper deposit with important resources and other commodities (Fe, Au, U) and Iron Oxide-Copper-Gold (IOCG) deposits, has caused great interest in formation processes and characteristic guidelines that are useful for their exploration. New discoveries have emphasized a hydrothermal …

Jan 01, 2005 · While copper can only dissolve by the action of oxygen, gold can dissolve either as the result of oxygen reduction (to peroxide or hydroxide) or as a consequence of copper (I) cementation: (18) Au o +Cu(CN) 2 − →Au(CN) 2 − +Cu o When ammonia is added to the gold–copper–cyanide system, copper can now exist as either copper (I) or copper (II), since ammonia ligates to copper (II) and helps …

Jan 01, 2016 · Abstract. Iron oxide copper–gold (IOCG) deposits contain economic or anomalous gold, and the gold distribution is important both for its economic significance and ore genesis. However, the gold distribution in IOCG deposits and its controlling factors remain unclear. The gold grades and tonnages of selected thirty-six deposits in some well-defined IOCG provinces are compiled in this paper

Jan 01, 2016 · Flotation and smelting are currently preferred for copper sulfide ores, but as yet there is no practical alternative to cyanidation for copper oxide ores. Iron–oxide–copper–gold (IOCG) deposits, however, are often amenable to flotation to generate a Cu–Au concentrate, with the recovery improving down through the orebody from the oxide zone to the transition and primary zones
