Preparation and microscopic characterization of magnetite-gold mesoparticles with tunable morphology
(Elsevier Science, 2015-12)
Composite magnetite–gold mesoscopic particles were prepared by deposition of Au onto magnetite nanoparticles. The surface morphology of the mesoparticles could be tuned by controlling the factors that affect the kinetics ...
Near-Field Enhancement Contribution to the Photoactivity in Magnetite-Gold Hybrid Nanostructures
(American Chemical Society, 2019-12)
Hybrid nanostructures composed of magnetic iron oxides and plasmonic metals can convert light energy into chemical energy, and they can be easily manipulated through magnetic fields. As a consequence of these multifunctional ...
A review of magnetite geochemistry of Chilean iron oxide-apatite (IOA) deposits and its implications for ore-forming processes
(Elsevier, 2020)
Magnetite is the most important iron ore in iron oxide-apatite (IOA) deposits which represent the Cu-poor endmember of the iron oxide-copper-gold (IOCG) clan. Magnetite chemistry has been used as a petrogenetic indicator ...
Trace elements in magnetite from massive iron oxide-apatite deposits indicate a combined formation by igneous and magmatic-hydrothermal processes
(Elsevier, 2015)
Iron oxide-apatite (IOA) deposits are an important source of iron and other elements (e.g., REE, P, U, Ag and Co) vital to modern society. However, their formation, including the namesake Kiruna-type IOA deposit (Sweden), ...
A Continuum from Iron Oxide Copper-Gold to Iron Oxide-Apatite Deposits: Evidence from Fe and O Stable Isotopes and Trace Element Chemistry of Magnetite
(Society of Economic Geologists (SEG), 2020)
Iron oxide copper-gold (IOCG) and iron oxide-apatite (IOA) deposits are major sources of Fe, Cu, and Au. Magnetite is the modally dominant and commodity mineral in IOA deposits, whereas magnetite and hematite are predominant ...
Formation of the Mantoverde iron oxide-copper-gold (IOCG) deposit, Chile: insights from Fe and O stable isotopes and comparisons with iron oxide-apatite (IOA) deposits
(Springer, 2020)
The Mantoverde iron oxide-copper-gold (IOCG) deposit, Chile, contains hundreds of millions of tonnes (Mt) of mineable iron oxide and copper sulfide ore. While there is an agreement that mineralization at Mantoverde was ...
A genetic link between magnetite mineralization and diorite intrusion at the El Romeral iron oxide-apatite deposit, northern Chile
(Springer Verlag, 2018)
El Romeral is one of the largest iron oxide-apatite (IOA) deposits in the Coastal Cordillera of northern Chile. The Cerro Principal magnetite ore body at El Romeral comprises massive magnetite intergrown with actinolite, ...
The geochemistry of magnetite and apatite from the El Laco iron oxide-apatite deposit, Chile: Implications for ore genesis
(Society of Economic Geologists, USA, 2020)
The textures of outcrop and near-surface exposures of the massive magnetite orebodies (>90 vol % magnetite) at the Plio-Pleistocene El Laco iron oxide-apatite (IOA) deposit in northern Chile are similar to basaltic lava ...
Thermal evolution of Andean iron oxide-apatite (IOA) deposits as revealed by magnetite thermometry
(Nature, 2021)
Magnetite is the main constituent of iron oxide–apatite (IOA) deposits, which are a globally important
source of Fe and other elements such as P and REE, critical for modern technologies. Geochemical
studies of magnetite ...
A flexible lab-on-a-chip for the synthesis and magnetic separation of magnetite decorated with gold nanoparticles
(Royal Soc Chemistry, 2015-01-01)
Magnetite decorated with gold nanoparticles (Fe3O4-AuNPs) is a ferrimagnetic material with unprecedented applications in immunosensors, as a contrast agent for imaging diagnosis, and for the photothermal ablation of tumor ...
