1. Introduction [2] The hemoilmenite ores from the Allard Lake area, Quebec, have been of interest for their magnetic properties since the 1950s [Hargraves, 1959a; Carmichael, 1961].Nearly 50 years later, Hargraves' interest was rekindled in these rocks with the discovery of magnetic anomalies on Mars and with the concept of lamellar magnetism [Robinson et al., 2002, 2004].

The detection of the magnetic properties of haematite plays an important role in the adjustment of the beneficiation process of haematite and the improvement of metal recovery. The existing methods for measuring the magnetic properties of iron ore either have large errors or take a long time. Therefore, it is very necessary to find a method that can quickly and accurately detect the .

The beneficiation of 200 µm haematitebased iron ore can be accomplished in principle using gravity concentration, flotation, or magnetic separation. However, in this case 60% of the material is finer than 10 µm, which makes magnetic separation the only viable option. The difficulty in recovering 10 µm haematite The recovery of 10 µm mineral particles is extremely difficult in .
KEYWORDS: Dry beneficiation, coal, fluidized bed, ilmenite, sand, fine coal, medium 1.

The beneficiation of ilmenite, the preferential removal of the iron oxides by selective chlorination, has been studied in a fluidized bed reactor. Temperatures from 700°C–950°C, inlet mole ratios of carbon monoxide (the reducing agent used) to chlorine (the oxidizing agent used) from 1–2, and a wide range of values of the ratio of initial bed weight to gasflow rate were investigated ...
Five main microstructural features characterize hematiteilmenite intergrowths from the Ecstall: (I) exsolution lamellae of hematite and ilmenite; (II) oxidation of ilmenite to form hematite, rutile, and other Tirich phases; (III) 2050 nm magnetite precipitates in hematite; (IV) rutile blitz texture; and (V) exsolution of hematite in rutile. Based on spatial relationships, textures II ...
