Properties of low-grade vanadium-titanium magnetite pellets (LGVTMP) with different MgO contents are investigated. Since MgO can ameliorate the properties of acid pellets, pure MgO reagent is added to LGVTMP as a MgO additive in this paper. The experimental results show that the compressive strength (CS) of different MgO-bearing LGVTMP has a ...
In this study, the magnetic fraction (MF) of a low-grade titanium ore (TO) was successfully used as an alternative Fe 2+ source in five reuse cycles, in combination with persulfate (PS) and simulated sunlight (SSL) for the degradation of ciprofloxacin (CIP). The best response of the CIP initial concentration, irradiation time, and doses of MF and PS to degrade completely this …

This present paper discusses both the dry and wet magnetic separation techniques used for processing of a low grade siliceous iron ore sample. 2. Materials and methods About 500 kg of a low grade siliceous iron ore sample was crushed to below 10 mm size by using jaw crusher.
Vanadiferous titanomagnetite (VTM) ore is an important natural multi-mineral co-associated magnetic material [1, 2].It is a mixture ore composed of several valuable mineral phases, like titanomagnetite, magnetite, ilmenite, coulsonite, hematite, rutile, quartz, etc. [3,4,5,6].Recently, a large number of low-grade vanadiferous titanomagnetite with high …
site for years. These dumps are generally low grade in nature and do not meet the quality norms for iron and steel making [2, 3]. Upgrading low-grade iron ores is becoming an attractive proposition today. The most commonly used beneficiation methods for iron ores are the gravity and magnetic separation techniques [4−6].

In low-grade VTM, valuable metal elements such as iron, vanadium, and titanium are mainly distributed in magnetite, with strong magnetic properties. Thus, magnetic …
But it's good to note that Titanium's magnetic susceptibility is very small and positive making its magnetic property very weak compared to ferromagnetic materials. This metal with 22nd position in the periodic table and with an atomic mass of 47.867, was discovered by the Reverend William Gregor, an English pastor, in the year 1791.
A large number of unexploited low-grade vanadium-titanium magnetite deposits have been found in the Chao-yang area of China in recent years. The reserves are estimated at more than 20 billion tons.
A typically low-grade titanium sand was first ground and then processed by low-intensity magnetic separation (LMS) and high gradient magnetic separation (HGMS) to recover titanomagnetite and ...

Gravity and magnetic separation are seen as promising low-cost recovery methods before final hydrometallurgical upgrading. The Company has also ...
An experimental research on comprehensive recovery of iron and associated apatite from a low grade vanadiferous titanomagnetite ore with high phosphorus was carried out. The results showed that using the technological flowsheet of "low -intensity magnetic separation-flotation", not only the magnetite can be effectively separated, but the associated apatite in the mineral …

To recycle TiO 2, we employed a non-blast-furnace metallurgy process for low-grade vanadia–titania magnetite (LGVTM), in which LGVTM was reduced by carbon and the valuable elements of Fe, Ti, V, and Cr were recovered by magnetic separation (G. Cheng et al., 2017). However, only approximately half of Ti was concentrated in the nonmagnetic ...
Titanium is a low-maintenance metal that does not need time-consuming care. ️; Titanium is scratch resistant because it is one of the strongest metals on earth. Titanium metal does not bend or stretch out of shape. It is very hypoallergenic. Hypoallergenic enough to be used in cases of artificial body parts and joint replacements.

The titanium-based lithium ion sieve adsorbent H 2 TiO 3 (HTO), known for its structural stability and high adsorption capacity, emerges as a highly promising material. Nonetheless, its precursor, the Li 2 TiO 3 powder (LTO), synthesized via the high-temperature solid-phase method, tends to agglomerate and poses challenges in separation. This agglomeration compromises the …
