chromites chemical transformations take place related to partial oxidation of bivalent iron and the formation of magnetite. This latter makes it possible to perform magnetic separation. However, these magnetic separation experiments appeared to be inefficient, because some amounts of iron, magnesium and chromium oxides moved to the non

This study aimed to evaluate the chromite recovery from shaking table tailings of Forumad plant by a dry high-intensity magnetic separation. The average feed grade of chromium trioxide (Cr2O3) was 7.62% by XRF. Also, different mineral phases were determined by XRD, identifying the presence of Chrysotile, Augite, Albite, Chlorite and Chromite.

Other suitable magnetic materials include oxides, such as, for example, ferrites, perovskites, chromites and magnetoplumbites. The particles can range in size from colloidal to about 10 microns. Separation of the resulting antibody-coated magnetic spheres 11 from liquid 12 is readily accomplished by actuating coil 16 and opening valve 17.

This procedure consists of magnetic separation in two stages, i. e. at a magnetic field strength of 5000 and at 11000 oersted. The concentration of chromite ore from the Kempersayi deposit according to the above procedure permits a decrease of SiO 2 (from 6.1 to 2.5% and CaO (from 1.3 to 0. 7%) and an increase of Cr 2 O 3 (from 51.7–52.3 to ...

Magnetic, electrostatic, and electrophoresis methods of mineral separations, singly or in combination, have been used successfully as tools in the separation and concentration processes of minerals. In this chapter, we have tried to describe and explain some of the relevant principles underlying the existence of such properties in minerals and ...

Gravity concentration is mainly used, and sometimes high- intensity magnetic separation, flotation being used in only a few instances. Heavy medium separation is the most economic method for treating coarse (10- 100 mm) particles, while finer particles are often treated by jigs, spirals and shaking tables.
