Abstract

The current practice of assessing the efficiency for recovery of magnetite by Davis tube tester at a magnetic induction is very important. 2nd factorial design is used for the parametric study of the magnetic separation because the classical approach is a tedious method. Factorial design is the most efficient way to explore the combinations of variables, because it uses every observation and calls only for as many observations as necessary. The results of the factorial experiments were used to identify the variables having a significant effect on magnetite recovery. The main objective of this work is to upgrade the iron ore using the Davis tube magnetic tester. It is also intended to study the most important operating parameters affecting the separation process. Among these are the feed size (µm), current intensity (Amp.), tube oscillation (rpm), tube inclination (degree) and wash water rate (Liter min-1). Consequently, the best fit relation can be expressed mathematically as: Y = 58.99 + 7.25X + 4.56I - 1.49O - 2.19W - 1.84S
