WebJul 1, 2000 · The ease with which such separation can happen depends on the density contrast between the crystals and the liquid, the viscosity of the liquid, the size of the crystals and the dynamics of the magma chamber system. Crystal separation can be facilitated by flow differentiation and filter pressing. WebFractional crystallization refers to processes which separate crystals from liquid. When this happens the liquid that remains is considered as a new magma. A number of processes can cause the crystals to be separated from a magma. Many minerals are denser than the liquid that they crystalize from. raven technology corp krs
