Abstract
Magnesium oxide and hydrogen chloride are produced from magnesium chloride containing solutions by atomizing the solution under its own hydrostatic pressure through nozzles into a spray drier to yield a magnesium chloride hydrate, preferably the dihydrate, which is then heated to at least 800 DEG C. The magnesium chloride hydrate may be separated from the heating gases by cyclones. The hydrate is then passed pneumatically or mechanically to a fission tube where it is drawn through with the heating gases to further cyclones which separate out the magnesium oxide formed from the heating gases which at this stage have a temperature of at least 800 DEG C., the hydrogen chloride formed being carried off with the gases. Alternatively the magnesium oxide may be formed directly from magnesium chloride solutions in the spray drier if the admission temperature of the heating gas is at least 1000 DEG C.
