Magnetic separators can be found in most mineral processing operations, especially those processing non-metallic minerals and magnetic ores. This article investigates the use of high intensity magnetic separators and magnetic separation equipment in the minerals sector with a focus on processing dry materials (in the -15mm, +45 micron size range).

Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO 3. Ilmenite is the primary ore of titanium, a metal needed to make a variety of high-performance alloys. Most of the ilmenite mined worldwide is used to manufacture titanium dioxide, TiO 2, an important pigment, whiting, and polishing abrasive. ADVERTISEMENT.

Further, the samples were subjected to magnetic separation using Permroll (14,000 Gauss) to separate magnetic and non-magnetic fractions and the representative weight percentages were recorded. The magnetic fraction was subjected to Carpco high tension separator (laboratory model, drum type) to recover conducting minerals (ilmenite and rutile).
