The effect of PSD on both the real density determination and mineral processing of the waste CSD from Palabora Copper (PTY) Ltd, Limpopo, South Africa had to be reduced via appropriate sample preparation. Afterwards, suitability for these tests was confirmed with the laser diffraction particle size analysis on both the as-received and 97% passing 300 Ám (d97 = 300) waste CSD; thus reporting %changes for particle size ranges of 148.00 to 248.90 Ám and 18.50 to 31.11 Ám as 1.53 and 0.00, 33.89 and 35.31 respectively. The real density of the waste CSD was then determined as 2.830. Whilst processing with the falcon concentrator, predominantly specific gravity controlled, produced concentrates with good grades at optimum conditions (21) of fluidization Water Flow rate and rotational Bowl Speed. However, it is recommended that another type of centrifugal separator be used to ascertain the chances of an improved grade.
