Method of forming phosphoric acid from phosphate ore

The present invention entails a method of forming phosphoric acid from phosphate ore by feeding the ore together with carbon source, which contains sulfur or carbon plus sulfur, to a kiln where the mixture is heated to reduce tricalcium phosphate occurring in the ore to a phosphorus gas The resulting phosphorus gas reacts with oxygen to form phosphorus pentoxide Thereafter the phosphorus.
