Binary mixture separation by batch distillation process The step by step procedure is described in figure 1. One disadvantage of the approach is that - at inferring the correlations - it has no clues to the multivariate distribution of the underlying variables, - can "conceive of" at most bivariate distributions, thus bases itself not on full information. Azeotropes reflect non ideal behaviour of mixture components that deviate from Raoult’s law. • The U mf of magnetite mixed with sand/gangue/coal were tested for coal beneficiation.
