MgCl 2. 6H 2 O, is an important ore, that often includes amounts of sodium chloride, generally as halite or sylvinite, a mixutre of halite and sylvite. The solution mining of carnallite has proven difficult since carnallite decomposes in the presence of water into its constituents with magnesium chloride going into solution more readily than

Example 17--Inverse Modeling With EvaporationEvaporation is handled in the same manner as other heterogeneous reactions for inverse modeling. To model evaporation (or dilution), it is necessary to include a phase with the composition "H 2 O".
