Abstract
The recovery of titanium from very fine particles of beach sand of Sri Lanka has been investigated using conventional hydrocyclone and novel magnetic hydrocyclone separation methods. A new design for a magnetic hydrocyclone has been developed using a permanent rare earth neodymium–iron–boron (Nd–Fe–B) magnet. Compared to the conventional hydrocyclone, this magnetic hydrocyclone was 5% more efficient in the recovery of titanium from the beach sand deposit with a commercial standard concentrate. It was also found that, for very fine particles, the titanium grade increased significantly (up to 56%
