Abstract
A process for the recovery of calcium chloride produced in the conversion of metal chloride by-products of chlorination to hydrous metal oxides. The hydrous metal oxides and other by-products of chlorination are insoluble in an aqueous solution of at least about 75 weight percent calcium chloride having a generally neutral pH and temperature between about 174 degrees centigrade and about 200 degrees centigrade. Calcium chloride also is readily recovered from the above solution.
