when do we use crystallization to separate components
Fractional Crystallization
As a magma crystallizes it undergoes fractional crystallization in which mafic minerals crystallize first and felsic minerals crystallize last. Therefore, as fractional crystallization occurs the magma becomes increasingly less mafic and increasingly more felsic. The viscosity also increases as a magma becomes more felsic.
ultramafic
Peridotite.
simply by crystallization of sugar or by fractional distillation
The impurities grab on to the growing crystals
A method of separation may be the fractional crystallization.
A major one is purification of semiconductors to prepare them for making transistors and integrated circuits.
Yes. You can definitely use crystallization in a sentence.
More felsic than the source rock.
Yes; through the process know as fractional crystallization, which changes the composition of the magma, therefore changing the minerals that eventually crystallize from it. Fractional crystallization occurs largely from the varying temperatures at which minerals crystallize.
Crystallization (if there is a liquid as well, you would use evaporation and crystallization) :)
