Problem Three:
In a counter current multistage leaching process, a feed (composed of solid
material B and solute A) containing 30 % of solute is to be extracted with pure
solvent C to remove 96 % of the solute. The feed rate is 1500 kg/h meanwhile
solvent rate is 400 kg/h. The final exit overflow solution contains 75% solute.
a. Calculate the amount and compositions of the exit streams.
b. The total number of theoretical stage.
