The ore is composed of magnetite and gangue minerals, which are mainly quartz. The flow sheet uses two stages of grinding and magnetic separation to reject quartz as early as possible. Vibrating screens with apertures of about 150
Magnetite as a Porphyry Copper Indicator Mineral in Till: a Test Using the Mount Polley Porphyry Copper-Gold Deposit, South-Central British Columbia (NTS 093A) L.K. Pisiak, School of Earth and Ocean Sciences, University of Victoria, Victoria, BC, [email protected]
Applications The Satmagan was designed especially to measure magnetite in iron ore concentrations. It can be used in various applications: Analysis of magnetite in iron ores, concentrates and tailings.
The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4). Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers.
Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself.
Keywords Characterization, Magnetite, Iron ore, Composition, Analysis 1. Introduction Characterization of a mineral ore is a very important step to perform before any processing takes place whereby quantity, grade or quality, densities, shape, and physical characteristics are determined to allow for appropriate application of technical and economic parameters to support production planning and ...
where Ɛ m is the magnetite recovery in concentrate, β 1 is the Fe grade of concentrate, β 2 is the S grade of concentrate, β 0 is the Fe grade of raw ore, β 3 is the S grade of raw ore, γ is yield of concentrate, and the rate of Fe to S is 1.59 in pyrrhotite. The equation is a criterion for evaluating the loss of magnetite.
Magnetite ore is a ferromagnetic material, with the chemical formula Fe3O4, and is one of several types of iron oxide. It is a ubiquitous mineral in many parts of the world, including Australia, the USA, Canada, South Africa, Mozambique and many other countries across most of the world's continents.
Magnetite is the principal iron-bearing ore mineral in these very old iron ores. Banded iron formation is the main source of iron although the majority of these deposits are from the Proterozoic. Bjørnevatn, Norway. Width of sample 17 cm.

hematite ore deposits are found in the eastern part of India and 82% of magnetite ore deposits occur in southern part of India, especially in the state of Karnataka. India possesses around hematite resources of 11,464 million tons of which 6,013 million
Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).
Analysis of mineral ores, concentrates, and high grade materials. The ore grade methods offered by Intertek are typically used in advanced exploration and for the evaluation of specific targets.The diverse suite of methods offered include those used for base metal and industrial mineral resource estimation.

The study of the thermogravimetric analysis provides an idea whether the ore is magnetite or not, although the FeO contain more or less same for samples. So the study is useful for grading an iron ore as per magnetite but not the basis of FeO content.

Boutroy et al. (2012) compared magnetite in Ni–Cu–PGE and iron oxide copper–gold (IOCG) deposits and showed that ore-stage magnetite in IOCG deposits contains lower Ni, Cu and Cr and higher Ti, Al and Si relative to primary magnetite in Ni–Cu–PGE deposits.
