    摘要： The process disclosed herein involves the high temperature processing of phosphate ore in a solid state using a ported rotary kiln. Prior to insertion into the kiln, the ore is pulverized and beneficiated to remove excessive quantities of unwanted materials such as clay, silica, iron, sodium, potassium, and alumina. The calcium oxide to silica ratio of the beneficiated is then adjusted to within a specific acceptable range, a carbon source containing sulfur such as petroleum coke is added and the resulting feed material is pelletized using a binding agent if necessary. The pelletized feed material is then dried, preheated, and fed into a ported rotary kiln. At the elevated temperature maintained in the reducing kiln, tricalcium phosphate undergoes a reduction reaction to produce phosphorus gas and carbon monoxide. Atmospheric air is injected into the rotating kiln chamber, which facilitates the oxidation of phosphorus gas to phosphorus pentoxide and the oxidation of carbon monoxide to carbon dioxide. The reducing kiln exhaust gas stream containing the phosphorus pentoxide and carbon dioxide gas components is processed in an absorption column in which the phosphorus pentoxide is hydrolyzed by water to phosphoric acid. The phosphoric acid is then recovered and concentrated to a commercial grade strength. The slag residue serves as a raw material for cement manufacture.
