Cr-bearing vanadia-titania magnetiteBlast furnaceHigh-temperature performancesEnergy savings and CO2 emissions reductionThe effects of CO2 injection on the high-temperature metallurgical performance of Cr-bearing vanadia-titania magnetite (CVTM) in blast furnace (BF) smelting were investigated. The dry ...
The hanging and footwall rocks are composed of light-colored anorthosite and leucogabbro that typically display a much coarser grain size (>5 mm for plagioclase) than the magnetite gabbro, which makes these rocks distinguishable from oxide-bearing rocks. In general, ilmenomagnetite is an Fe-, ...

Exploitation of the cation ordering effect should allow us to constrain thermal histories of titanomagnetite-bearing rocks for ToTclosure. Similar geospeedometers have been developed for orthopyroxene36 and other silicates37–39, but the advantage of using titanomagnetite is that TC is an easily ...
And this hints that the magnetites, which have a paragenesis relationship with ore-bearing garnets, should be also a product of hydrothermal fluid replacement with wall rocks, and most of the mineralizing materials (Fe) probably are derivate from andesitic strata. In combination geological ...

By definition of an exclusion criterion based on the ratio of saturation magnetization over volume susceptibility, greigite-bearing samples were removed from the palaeomagnetic data. Thus, only 25–55 per cent of the samples were left in the palaeomagnetic records obtained from sediments from the ...
The high-temperature metallurgical property of high-titania slag is one of the most significant indicators to measure the production status of Cr-bearing vanadia-titania magnetite blast furnace (CVTM-BF). Due to the continuous high temperature in the furnace, titania is over-reduced to titanium ...
On the other hand, the contents of Co, Ni, Mo, Sn, Zn and Pb in magnetite would be affected by sulfides because these elements can partition into both magnetite and sulfide phases in sulfide-bearing magmatic and hydrothermal systems. For example, in magmatic sulfide deposits, Ni partitions ...
