The gold distribution is controlled by gold contents in host rocks and the efficiency of precipitation mechanism. Iron oxide …
Herein, we report a new sensor, a reduced graphene oxide stabilized binary copper–iron oxide-based nanocomposite on a 3D printed Ag-electrode (Fe–Cu–rGO@Ag) for detecting a wide range of blood creatinine (0.01 to 1000 μM; detection limit 10 nM) in an electrochemical chip with a current density ranging between 0.185 and 1.371 mA/cm 2 …
Iron oxide-copper–gold (IOCG) deposit genesis is often genetically linked to magmatism due to temporal association between granite and mineralization and participation of magma-derived components. In the Carajás Mineral Province, NW Brazil, a set of ca. 2.6–2.5 Ga IOCG deposits has been interpreted to be genetically linked to contemporary granite, …

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 mineral species and large scale. This paper presents a review of the present IOCG deposits research, which …
Copper is a metallic element with relatively low abundance in the earth's crust compared to aluminum and iron, ranging from 0.005 to 0.01% [1, 2].Typical copper ores with economic value contain copper in open pit mines and underground mines over 0.3% and 1.7%, respectively [].According to the proportion of mineral phases in ore deposits, …
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 ...
Several Cr-free copper–iron oxide-based high-temperature water−gas shift catalysts were prepared with the Al promoter (3Cu8AlFe), Ce promoter (3Cu8CeFe), and copresence of both promoters (3Cu5Al3CeFe, 3Ce/3Cu8AlFe, and 5Ce/3Cu8AlFe). The 3Cu8CeFe catalyst exhibits the additional presence of a Ce–Cu–O mixed oxide phase in …
Precambrian iron oxide copper-gold (IOCG) deposits are generally encountered with multistage hydrothermal overprints and hence have complex isotopic records. Precise dating of ore-forming and over events and assessment of time-resolved metal sources are fundamental for understanding ore genesis. Here, we …

Predictive magnetic exploration models for porphyry copper and iron oxide copper–gold (IOCG) deposits can be derived from standard geological models by integrating magnetic petrological principles with petrophysical data, deposit descriptions, and modelling of observed magnetic signatures of these deposits. Even within a …
Iron oxide‐copper‐gold (IOCG) deposits are a globally important source of copper, gold and critical commodities. Despite their relevance, IOCG deposits remain an ill‐defined clan, with a ...
1. Introduction. Iron oxide copper gold (IOCG) deposits, first defined as such in the 1990s (Hitzman et al., 1992; Oreskes and Einaudi, 1992), represent a spectrum of magnetite- and/or hematite-rich hydrothermal Cu Au deposits (Corriveau et al., 2010; Barton, 2014).However, the viability of the deposit class remains controversial due to the …
Considering that iron sulfide (FeS 2) has attracted much attention due to its excellent peroxidase-like activity in acidic medium, narrow band gap (Eg = 0.95 eV) and high absorption coefficient [26], herein, an alternative GO supported bimetallic copper and iron sulfide nanocomposite (GO/CuFeS x NC) is developed as a novel binary antibacterial ...

Iron-oxide-copper–gold (IOCG) deposits are characterized by Cu-Au polymetallic mineralization and may contain large amounts of critical metals (e.g. Co, REE, and U) as by-products.
Each metallogenic epoch introduced its own deposit type(s), of which porphyry copper (and related skarn), followed by sediment-hosted stratiform copper and then iron oxide copper-gold (IOCG), are globally preeminent. Nonetheless, genesis of the copper provinces remains somewhat enigmatic and a topic of ongoing debate.
The Southern Copper Belt, Carajás Province, Brazil, hosts several iron oxide–copper–gold (IOCG) deposits, including Sossego, Cristalino, Alvo 118, Bacuri, Bacaba, Castanha, and Visconde. Mapping and U–Pb sensitive high-resolution ion microprobe (SHRIMP) IIe zircon geochronology allowed the characterization of the host …

Strong metal–support interactions between metallic copper and iron oxides were observed during the high-temperature water-gas shift (WGS) reaction. Such a synergistic interaction not only stabilizes the Cu clusters, but also provides new catalytic active sites that facilitate CO adsorption, H 2 O dissociation, and WGS reaction.
