Thermal plasma processing of ilmenite: a review Taylor

The use of thermal plasma in material processing industries is becoming an increasingly active and attractive field for the development of new technology. The potential applications of thermal plasma processing technology cover a wide range of activities such as the extraction of metals and the refining/alloying of metals/alloys/minerals.Ilmenite is an essential mineral for the extraction of titanium. Conventional physical separation methods have difficulty recovering fine ilmenite, and dressing plants have begun applying flotation to recover ilmenite. The interaction of reagent groups with Ti and Fe sites on the ilmenite surface dramatically influences the ilmenite flotation. Reagent types and action mechanisms in ilmenite flotation: A

Reforming of coal volatiles over ilmenite ore ScienceDirect

Ilmenite greatly increased its reactivity with coal volatiles after being pre-oxidized at 1173 K. There was no tar formation during steam reforming of coal volatiles when pre-oxidized ilmenite was used as an oxygen carrier. Fuel Processing Technology, Volume 192, 2019, pp. 1-12.

Behavior of ilmenite as oxygen carrier in chemical-looping combustion

Ilmenite is a common mineral found in metamorphic and igneous rocks. The ilmenite used is a concentrate from a natural ore. Fresh particles have been exposed to thermal pre-treatment at 950 °C in air during 24 h, since it improves its performance as oxygen-carrier [30], [31]. Table 1 shows the main properties for calcined ilmenite. The The ilmenite lain in ultrafine ilmenite ore cannot be treated easily. In this study, a superconducting magnetic separator (SMS) was proposed to preconcentrate the ultrafine ilmenite. During this process, the essential condition for capturing the ilmenite from the ultrafine ore, key technology for obtaining an efficient preconcentration, and Preconcentration of ultrafine ilmenite ore using a

Methods of Extracting TiO2 and Other Related Compounds from Ilmenite

In the industrial production of TiO 2, the sulphate process and chloride process are the two common methods utilized for extracting TiO 2 from ilmenite and rutile, respectively. 2.1. Sulphate Process. Statistical data reveal that 98% of manufacturers in China use the sulphate process for the production of TiO 2 [ 33 ].However, only ilmenite, leucoxene, and rutile have crucial commercial value. Ilmenite and rutile are the two main titanium minerals used in industrial applica-tions, mainly for titanium metal production and pigment-grade titanium dioxide [19]. 4.
