Natural Convection Effects on Magnesium Solution Mining

Raw magnesium chloride can be recovered using solution mining at a depth of a 1500 to 2000 meters. Underground caverns are formed in stacked layers of bischofite , carnallite and halite. The salt layers consist for a large part of NaCl and but contain a minimum of at least 35% magnesium chloride. Recovery is implemented by injection of fresh...
