Magnesium element extraction method solution mining technique

The process requires seawater to be mixed with lightly burnt dolomite in a flocculator causing precipitates of insoluble magnesium hydroxide to settle at the bottom of the tank. This Mg(OH) 2 is pumped out as a slurry and then filtered and converted to magnesium chloride by treating it with Hydrochloric (HCl) acid and dried.
