Continuous heavy liquid concentration of kyanite.
NTIS: PB 198 285 :1-11
Laboratory semicontinuous and continuous heavy liquid cyclone separation pilot plant tests were made to determine the feasibility of producing a high-grade kyanite concentrate from a kyanite-quartz rock sample from Graves Mountain, Georgia. Use of a three-stage heavy liquid cyclone demonstrated that a 96.4- to 99.0-percent kyanite concentrate could be obtained with recoveries of 95.5 to 96.7 percent. The test work showed that by steam stripping with 6.9 Tons of steam per ton of ore and two stages of detergent scrubbing the residual tbe content of kyanite cyclone products was 0.22 Pound per ton of ore. Work done in cooperation with University of Alabama.
