Question:
It all depends upon what substance(s) the impurities is(are), and what the
concentration(s) is(are). Some impurities "fit" right into the growing
crystal lattice, while others are either excluded, or alter the growth
pattern of the crystal. Generalizations are difficult to make.

Hi Megan!
It will depend what these impurities are and how much.
If it is in a big quantity (some how) and
crystallizable class they will grow like another type
of crystal, or very small quantities could be included
(inside) the big crystal. If both material have the
same crystal characteristics maybe they could form
a mixed crystal.
Any way consider that fractional crystallization is a
way (process) to purify crystals with impurities.
