According to the mass balance, the space vacated or occupied by departing or incoming particles, respectively, must be accounted for by the liquid medium, because this flow of particles occurs within the open liquid area. This implies that, if a given volume of particles moves in the z direction, then the same volume of liquid will have to move in the –z direction. The rate of liquid in the element is given by © 2003 by the Society for Mining, Metallurgy, and Exploration. All rights reserved. Electronic edition published 2009.

25 26 GRAVITY CONCENTRATION FUNDAMENTALS PART II—FLUIDIZATION STUDIES In this section, some recent fluidization work concerned with generating data on the size and density distribution of a particle feed is described. Knowledge of the size and density distributions is fundamental to describing the gravity separation and size classification of actual feeds consisting of a broad range of particle sizes and densities, including the grade recovery curve. The measurement of the density distribution is far from trivial and poses increasing concerns on health and environmental grounds when dense liquids need to be used.

Electronic edition published 2009. 41 42 GRAVITY CONCENTRATION FUNDAMENTALS The remaining solids settle in the column, building a high-density, fluidized bed. The height or thickness of the bed is measured using a differential pressure sensor (see Figure 1), which is monitored by the PID controller. The desired bed thickness is maintained by opening and closing a pneumatically-actuated pinch valve, which is controlled by the PID controller.
