Abstract

Magnesia is obtained from calcined and slaked dolomite by treatment thereof with carbon monoxide under pressure, and removal by leaching of the calcium formate produced. An example is given. The calcium formate may be converted to formic acid, alkali formate, or potassium carbonate by known methods.ALSO:Calcium formate is obtained by treatment of calcined and slaked dolomite with carbon monoxide under pressure and is separated by leaching from the residual magnesia. An example is given. The calcium formate may be converted to formic acid or alkali formates by known methods.
