FIBER OPTIC DETECTOR FOR FLOTATION CELL PROCESSING

摘要

An apparatus for determining the reflectivity of the tailings from a coal flotation cell to optimize the cell operation. A bifurcated fiber optic cable has ends connected to a light source and a photoconductor, with a scanner end of the cable being submersed in a coal slurry. Light transmitted to the scanner end of the cable is backscattered to the photoconductor to function as a detector to determine the coal content of the tailings and through a process controller, frother and collector addition to the cell is monitored. An ultrasonic energy vibration is periodically transmitted to the scanner end of the cable to remove deposits thereon to optimize detector operation.
