trace element chemistry of magnetite from the malmberget

Minerals Free Full-Text Trace Elements in Magnetite ...

Magnetite is a common accessory phase in various types of ore deposits. Its trace element content has proven to have critical implications regarding petrogenesis and as guides in the exploration for ore deposits in general. In this study we use LA-ICP-MS (laser ablation-inductively coupled plasma-mass spectrometry) analyses of trace elements to chemically characterize magnetite

Trace elements in magnetite as petrogenetic

2014-6-10  We have characterized the distribution of 25 trace elements in magnetite (Mg, Al, Si, P, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Ga, Ge, Y, Zr, Nb, Mo, Sn, Hf, Ta, W, and Pb), using laser ablation ICP-MS and electron microprobe, from a variety of magmatic and hydrothermal ore-forming environments and compared them with data from the literature. We propose a new multielement diagram, normalized ...

Mineral chemistry of magnetite from magnetite

Interpretation of the mineralizing environment of magnetite-apatite deposits remains controversial with theories that include a hydrothermal or magmatic origin or a combination of those two processes. To address this controversy, we have analyzed the trace element content of magnetite from precisely known geographic locations and geologic environments from the Precambrian magnetite-apatite ore ...

Trace element associations in magnetite and hydrothermal ...

2019-11-21  Trace element distribution patterns in magnetite and pyrite indicate that As, Ni, Co, Cr, Mn and Cu were mostly locally derived, and remobilised into the pyrite during sulfidation of the host rock. The concentrations of these elements are strongly lithologically controlled, and they are not consistently incorporated into the pyrite after initial stages of growth.

New insights on the evolution of the Lyon Mountain

The magnetite-apatite deposits within the Lyon Mountain Granite (LMG) in the northeastern Adirondack Highlands of New York State are similar to the deposits in northern Sweden and lack Cu and Au in economic concentrations, but have high concentrations of REE in some apatite associated with mineralization (Lindberg and Ingram, 1964; Roeder et al., 1987; Valley et al., 2010).

The Bafq-Saghand metallogenic belt is located in the central part of the Kerman–Kashmar tectonic zone and contains 39 individual occurrences of iron oxide-apatite ± REE mineralizations. These mineral concentrations, e.g., Chadormalu, Choghart, Sechahun, and Esfordi, comprise a total of ~ 1500 million tons of iron ore with an average grade of ~ 55% Fe. In terms of origin, time, and ...

Trace element distribution into Ca-Mg-carbonates depends on X Mg, temperature and seems to follow lattice constraints for divalent cations. Partition coefficients of REEs between magnesite (Ca 0.11 Mg 0.89 CO 3 ) and dolomitic melt (Ca 0.5 Mg 0.5 CO 3 ) at 6 GPa and 1400 ℃ are uniform scattering marginal between 0.1‑0.2.

2016-10-31  The acid leaching or bio-leaching is used for the dephosphorization of high phosphorus-containing iron ore. It was reported that acid leaching of high phosphorus-containing iron ores could dramatically reduce the phosphorus content in concentrates [13 – 16].For example, the hydrochloric acid leaching of an iron ore containing 1.16% phosphorus removed 98% phosphorus at a particle size of
