Size-by-size analysis of dry gravity separation using a 3-in. Knelson

The motor power (%), solid feed rate (g/min) and air fluidising pressure (psi) were chosen as independent variables, with five levels (±β, ±1, 0 where β = 2 3/4 = 1.682) for each variable, with the response variable being the tungsten recovery for each size fraction. Because the controller of the Knelson Concentrator indicates the motor power …
