Abstract
Wet low intensity magnetic separation studies for a synthetic binary mixture of magnetite and quartz were carried out. The variables studied were particle size, magnetic field intensity, and wash water rate. Experiments were carried out using 23 full factorial designs. The main and interaction effects on the separation efficiency were evaluated using Yates' analysis. The optimum magnetic separation conditions were calculated by the method of steepest ascent. A concentrate with 98.9% magnetite at 87.2% component recovery and 86.3% separation efficiency was obtained at following optimum conditions: 200 µm particle size, 3190 Gauss magnetic field intensity, and 402 cm3/min wash water rate.
