  • Advances in Centrifugal Gravity Concentration Beyond

    Silver recovery of 66% at a mass yield of 18% was achieved on the ball mill discharge sample. Since gravity concentrators operate most efficiently on narrow size fractions and the mill discharge contained a wide particle size distribution, these results are especially encouraging. The grade and distribution of the silver is significantly higher in the fine fractions within a coarse feed sample

  • The influence of mill speed and pulp density on the

    mill discharge density (before dilution) obtained during the sampling. The ball charge, and hence the volume of the voids between the balls in the mill, is known and we are then able to calculate the factor ‘volume pulp/volume voids between the balls’. Repeatability The repeatability of the pilot plant was investigated in the past with 2 repeat test runs with the ∅0.82 x 1 m grate
