• Rod mill kinetics of Egyptian feldspar Mineral Processing

    AbstractThe rod mill kinetics of Egyptian feldspar (albite from South Sinai and feldspathic sand from Eastern Desert) has been investigated as part of a study on the beneficiation of feldspar to develop means of predicting size distribution from processing parameters. A mass balance model has been developed to simulate the grinding of feldspar.
