Microwave cavity perturbation technique for measuring the moisture content of sulphide minerals concentrates

The moisture content of a sulphide mineral concentrate was measured by the microwave cavity perturbation technique. Comparative experiments were performed using this technique and by oven drying. It was found that the deviation in the measurement of the moisture content of the concentrate was less than 0.5%, indicating that this would be a suitable technique for moisture content determination of sulphide mineral concentrates.
