As the temperature of rock rises the individual mineral components begin vibrating and the intermolecular bonds holding minerals together begin to stretch.

minerals that crystallize directly from ocean waters
Minerals that crystallize directly from seawater are examples of evaporite minerals. These minerals form when seawater evaporates, leaving behind dissolved minerals that precipitate and crystallize into minerals like gypsum, halite, and calcite. Evaporite minerals are commonly found in areas with high rates of evaporation, such as salt flats and arid regions.
The existing minerals are re-formed by the heat and pressure into a new assembly of minerals, at least in part to minimize the volume. The new minerals will crystallize out at their natural freezing points, and some of the micas are the last to crystallize out. The time of this terminal event is taken as the age of the rock or of that metamorphic event.
Minerals in magma crystallize through the process of cooling and solidification. As magma cools, atoms and ions within the molten rock arrange themselves into an ordered, repeating three-dimensional pattern, forming mineral crystals. The specific minerals that crystallize depend on factors such as temperature, pressure, and chemical composition of the magma.

Minerals remain as a solid residue.
Yes, minerals can crystalize when magma melts.
Minerals crystallize from a solution.
Deep in the Earth, minerals are dissolved in the hot, high pressure water underground. That water seeps upwards into cracks in the rock. As it rises, it both cools and lowers in pressure. These reduce the ability of the water to hold the minerals in solution. The minerals crystallize in the cracks, forming the veins of mineral ore.
The first ferromagnesian mineral to crystallize is usually olivine, followed by pyroxene and amphibole. Among the feldspars, plagioclase feldspar is usually the first to crystallize, followed by potassium feldspar.
