Distillation, sublimation, and recrystallization use a change in physical state as a means of separation. Chemical reactivity also can be a useful tool for separating analytes and interferents. For example, we can separate SiO 2 from a sample by reacting it with HF to form SiF 4. Because SiF 4 is volatile, it is easy to remove by evaporation. If we wish to collect the reactions volatile product, then a distillation is

This separation can often be achieved by physical means since mineral and gangue generally occur as separate solid phases. The process of removal of gangue from the ore is technically known as concentration or ore dressing and the purified ore is known as concentrate. These are various physical and chemical process involved in this step.

Separation methods, then, can be defined as processes that change the relative amounts of substances in a mixture. In chemical methods, one may start with a completely homogeneous mixture a solution or a heterogeneous sample e.g., solid plus liquid; in the act of separation, some particles are either partially or totally removed from the sample.

Calculating the concentration of a chemical solution is a basic skill all students of chemistry must develop early in their studies. What is concentration? Concentration refers to the amount of solute that is dissolved in a solvent. We normally think of a solute as a solid that is added to a solvent e.g., adding table salt to water, but the solute could easily exist in another phase.
