Abstract
This invention relates to an apparatus and method for controlling the operation of a coal preparation plant. The apparatus includes a sampling device (6,7) which takes a sample of the tailings from the plant. The sample is concentrated in a concentrator (e.g. cyclone separator (8)), which produces a concentrated sample having a solids content of about 30%, which is sensed by nucleonic sensor (10) which produces a signal proportional to the contaminant content of the tailings. The apparatus may also include a density meter (9) which produces a signal proportional to the density of the sample, which signal may be combined with the contaminant sensor signal to give a combined signal which is more accurately proportional to the contaminant content of the tailings than is the contaminant sensor signal alone. Either signal may be used to vary the action of a control device, which controls the operation of a part of the plant or operates an alarm. The present invention allows the continuous and automatic monitoring and control of the operation of a coal preparation plant. The invention is envisaged as of being in use in mineral preparation plant, and in particular in coal preparation plants. <IMAGE>
