Kaolin Beneficiation in a High–Gradient Magnetic Separator With a Ball Matrix
1993
Results are given of investigations into the determination of the
main structural and technological parameters of a high–gradient magnetic
separator with a ball matrix. The design has been developed and a
possibility has been outlined of effective beneficiation of kaolin at the
magnetic induction 1.0 to 1.2 T. Comparative tests of separators with a ball
matrix and a steel wool matrix (SALA–HGMS) have shown that the
parameters of separation are the same. In the former case, however, a
considerable reduction in specific input of metal, electrical energy, water
and air per tonne of product is achieved. The advantage of the ball matrix
is most fully displayed at the extraction of finely dispersed weakly magnetic
particles from ores and slimes of low content of magnetic fraction.
