Seven signals were accurately measured and data logged in exhaustive experiments using a highly instrumented and controlled pilot scale Baum jig. These signals provide a basis for understanding the effect of the operating parameters on the air and water behaviour in the jigging process. The measurements include the air pressure, water pressures and displacement, the hutch water flowrate. A Fourier decomposition method was applied to remove signal noise and smooth the signals. Water velocities and accelerations are calculated from the smoothed displacement data.
