This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from : % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.

v117n4a12 Recovery of iron from iron ore slimes by ...

iron ore slimes decreases with increasing pulp density and increases with increasing pH. The maximum settling rate of 1.1 cm/s was obtained at pH 12 using a pulp density of 1% by weight. This may be attributed to the fact that at higher pH values all the particles (both iron and gangue minerals) tend to settle.
