WebThese are some examples of magmatic ore minerals. The formation of magmatic ore minerals is closely linked to the processes of magma generation, crystallization, and hydrothermal activity associated with igneous rocks, and the identification and extraction of these minerals are important in the exploration and exploitation of mineral deposits. WebFractional crystallization is the removal and segregation from a melt of mineral precipitates; except in special cases, removal of the crystals changes the composition of the magma. [2] In essence, fractional crystallization is the removal of early formed crystals from an originally homogeneous magma (for example, by gravity settling) so that these crystals … WebFractional crystallization is a method of refining substances based on differences in solubility.
