| Summary: | Includes bibliographical references. === On-line measurement of the moisture content of process streams in a mineral processing plant is vital for their efficient operation. Although many industrial moisture meters are available, most of these were designed to determine the moisture content of low density, fine grained, uniformly surfaced and low resistance materials. Consequently these meters operate poorly on mineral treatment plants as the measured material, rock, is dense, uneven and consists of mixtures of various minerals. A literature survey revealed that of the many methods available, only three techniques could be used for on-line moisture determination in mineral processing operations.These were microwave attenuation, phase and frequency techniques.
