1.16: Methods for Separating Mixtures
Distillation is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated. In simple distillation, a mixture is heated, and the most volatile component vaporizes at the lowest temperature. The vapor passes through a cooled tube (a condenser), where it condenses back into its liquid state.

PHYSICAL SEPARATION PROCESSES
Physical separation techniques separate a mixture such as a crude oil without changing the chemical characteristics of the components. The separation is based on differences of certain physical properties of the constituents such as the boiling and melting points, adsorption affinities on a certain solid, and diffusion through certain membranes.
Pre-concentration of nickel in laterite ores using physical separation
For example, in a nickel-cobalt laterite deposit in New South Wales, Australia, gravity separation followed by magnetic separation resulted in upgrading nickel from 0.9% to 1.1% at 57% recovery (Aral, 2013). Furthermore, Muir and Johnson (2006) demonstrated that in physical beneficiation using gravity, particle size is the key parameter.
