Ore refers to a collection of minerals from which useful components can be extracted or which themselves have some property that can be exploited. Can be divided into metal mineral and nonmetal mineral. The unit content of useful components (elements or minerals) in the ore is called ore grade, precious metal ores such as gold and platinum are expressed by gram/ton, other ores are expressed by percentage, and the value of the ore is measured by the grade of the common ore, but the value of the ore is also influenced by the components and harmful impurities of gangue (useless minerals or minerals with little useful components in the ore and unavailable use) in the effective component ore.

Separation and purification means separating impurities from a mixture to improve the purity of the mixture. The separation and purification as an important chemical method has important functions in chemical research and chemical production, and the separation and purification are mainly used in many important chemical research and chemical production.
