Many diverse ore systems are classified together as iron oxide coppergold (lOCG) deposits based on an empirical definition arising primarily from geochemical features that do not specify tectonic setting, geologic environment, or sources of oreforming fluid, metals, or other ore components. Such deposits have (1) Cu, with or without Au, as economic metals; (2) hydrothermal ore styles and ...
Iron oxide coppergold (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 ...
Jul 17, 2018· Trace element compositions of magnetite and hematite from 16 wellstudied iron oxide–copper–gold (IOCG) and iron oxide apatite (IOA) deposits, combined with partial least squaresdiscriminant analysis (PLSDA), were used to investigate the factors controlling the iron oxide chemistry and the links between the chemical composition of iron oxides and hydrothermal processes, as .
Gossan, rustcoloured oxide and hydroxide minerals of iron and manganese that cap an ore deposit. Gossans form by the oxidation of the sulfide minerals in an ore deposit and they thus may be used as clues to the existence of subsurface ore deposits, especially if distinctive boxworks are present.
The iron oxide coppergold (IOCG) group of deposits, initially defined following discovery of the giant Olympic Dam CuUAu deposit, has progressively become tooembracing when associated deposits and potential end members or analogs are included. ... The giant size of many of the deposits and surrounding alteration zones, the highly saline ore ...

Many of these issues arise from our limited understanding of the fundamental similarities and differences between the very broad range of iron oxidebearing deposits of copper and gold in different ore deposit types, only some of which should be described as IOCG deposits ( Groves et al., 2010).

This paper provides an overview on the genesis of Mesoproterozoic igneous rocks and associated iron oxide ± apatite (IOA) ± rare earth element, iron oxidecoppergold (IOCG), and ironrich sedimentary deposits in the St. Francois Mountains terrane of southeast Missouri, USA. The St. Francois Mountains terrane lies along the southeastern margin of Laurentia as part of the eastern granite ...
You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.
