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.
Research on fluid inclusions in Iron Oxide Copper Gold hydrothermal systems has significantly progressed over the past few decades. This paper summarizes the major research advances including petrography, microthermometry, and the compositional of fluid inclusions, as well as the main theories regarding the origins and evolution of ore formation.
Iron oxide‑copper‑gold (IOCG) deposits are a rare type of magmatic-hydrothermal deposits that were initially proposed for the giant Olympic Dam deposit and Cu-Au deposits in the Cloncurry region, Australia (e.g., Hitzman, 2000; Williams et al., 2005; Groves et al., 2010).They are commonly hosted within breccia bodies and are related to regional-scale hydrothermal …
Iron oxide-copper-gold (IOCG) deposits, defined primarily by their elevated magnetite and/or hematite contents, constitute a broad, ill-defined clan related to a variety of tectono-magmatic settings.

Iron oxide copper-gold (IOCG) deposits are a research focus of the current ore deposit geology, and have attracted much attention among the worldwide geologists and exploration experts due to their shallow depth, a wide variety of …
One is a high gold grade with high copper content and the other is a low gold grade ore type. These two sample types were chosen because the high-copper high-gold grade ore type is anticipated to be the most difficult ore type to process and the low-gold grade ore type represents the largest portion of the refractory ore resource.
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 …

Many diverse ore systems are classified together as iron oxide copper-gold (lOCG) deposits based on an empirical definition arising primarily from geochemical features that do not specify tectonic setting, geologic environment, or sources of ore-forming fluid, metals, or other ore components. Such deposits have (1) Cu, with or without Au, as economic metals; (2) …
Iron oxide-copper-gold (IOCG) systems are among the world's richest mineral deposits, making for highly pro˜t - able mining operations 1–3 . By-product strategic elements including Co, U and ...
Trace element compositions of magnetite and hematite from 16 well-studied iron oxide–copper–gold (IOCG) and iron oxide apatite (IOA) deposits, combined with partial least squares-discriminant analysis (PLS-DA), were used to investigate the factors controlling the iron oxide chemistry and the links between the chemical composition of iron oxides and …
The global gold ore grade has been decreasing, and the mineralogy is now more diverse and complex. This has necessitated the utilization of low-grade ores previously not used. During the cyanidation process of such ores, copper cyanide complexes form that are competitively adsorbed with gold onto activated carbon. Therefore, to decrease the amount of …
Hydrothermal iron oxide-copper-gold (IOCG) ore deposits are globally important sources of Cu and Au. ... 2008) was used for signal processing, including spike elimination and element quantification. Signal intervals showing impurities from fluid inclusions, silicates, carbonates, iron oxides, sulfides, and uranium-rich minerals were detected as ...
In the following sub-sections, the most widely-applied physical separation techniques in gold processing – ore sorting, screening, gravity concentrators and froth flotation – are presented. ...

A government airborne geophysical survey flown in the late 1970s detected a large Magnetic anomaly at Gadarwara, Madhya Pradesh, in north-central India. Deep drilling indicates that the oval-shaped Magnetic anomaly is caused by underlying Magnetite-bearing banded iron formation belonging to the Mahakoshal Formation of Archean to Early Proterozoic age. The …
