Ilmenite an overview ScienceDirect Topics

A process has been developed [7] by which alumosilicate, zircon, and ilmenite were recovered separately. Initially ilmenite was recovered using magnetic separation. The nonmagnetic fraction is stage conditioning at 60% solids with HF and alpha sulfostereic acid followed by pulp dilution to 25% solids and zircon + alumosilicate bulk concentrate was recovered while silica reported to the tailing.

A review of mineral processing of ilmenite by flotation

2020-10-1  For ilmenite, its specific gravity is generally higher than its associated gangue consisting mainly of silicate minerals, and therefore selective separation of ilmenite from gangue by gravity separation is rational and can be employed in some industrial practices.

Magnetic properties of ilmenite, hematite and oilsand

2002-12-1  There is little information on the roasting of ilmenite below 800 °C except for Walpole’s patented process for ilmenite recovery from mineral sands by a magnetizing roast between 650 and 900 °C (Walpole, 1997). Similarly, little is known about how an oxidation roasting environment, such as the one that may be encountered in oil sands tailings treatment, would affect the magnetic properties and separation behavior of ilmenite.
