Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin.

2023年6月12日 · Iron oxide copper gold ore refers to the symbiosis of copper ore and gold ore in gold ore in some form. Its amount is about 10 million to 4 billion tons. IOCG ore contains copper with a grade of 0.2% to 5% and gold with a content of 0.1 to 1.41 grams per ton.

2022年1月1日 · The diverse group of iron oxide copper-gold (IOCG) deposits has been one of the most contentious classes of ore deposits since its recognition as a new type in the mid 1980s to early 1990s.

Iron oxide–copper–gold (IOCG) systems, initially defined following discovery of the giant Olympic Dam Cu–U–Au deposit (Fig. 3.12), comprise magmatic-hydrothermal deposits that: (1) contain economic Cu ± Au ± U grades; (2) are structurally controlled, commonly with breccias; (3) have abundant low-Ti iron oxides intimately associated ...

2016年1月1日 · Iron oxide copper–gold (IOCG) deposits contain economic or anomalous gold. The gold is present as native gold, electrum, and gold–bismuth–antimony–tellurium alloy. The gold distribution is controlled by gold contents in host rocks and the efficiency of …

Iron oxide copper (-gold) deposits are an emerging ore type of importance to the minerals industry, as illustrated by the recent discoveries of Sossego-Sequerinho and Crystalino

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 ...

The iron oxide copper-gold (IOCG) group of deposits, initially defined following discovery of the giant Olympic Dam Cu-U-Au deposit, has progressively become too-embracing when associated deposits and potential end members or analogs are included.

2019年1月1日 · Iron oxide copper-gold (IOCG) deposits are hydrothermal deposits characterized by abundant low-Ti Fe oxides, economic Cu-Au grades, structurally controlled orebodies, widespread presulfide alkaline alteration, and commonly significant volumes of breccia.

Many diverse ore systems are classified together as iron oxide copper-gold (IOCG) deposits based on an empirical definition arising primarily from geochemical features that do not specify tectonic setting, geologic environment, or sources of …
