1. A PROCESS FOR RECOVERING PHOSPHORUS VALUES AND A CALCIUM SILICATE CEMENT CLINKER FROMA PHOSPHATIC ORE WHICH COMPRISES (A) INTRODUCING ABOUT A -10 MESH PHOSPHATIC ORE INTO A DESLIMING CLASSIFER, (B) WATER WASHING -10 MESH PHOSPHATE ORE TO REMOVE SMALL COLLOIDAL PARTICLES BELOW ABOUT 5 MICRONS CONTAINING LOW FUSION POINT IMPURITIES AS SLIMES FROM THE PHOSPHATE-CONTAINING PARTICLES, (C) MIXING THE DESLMED PHOSPHATE ORE WITH ALUMINA, SILICA AND CRUSHED LIME TO PRODUCE A MIXTURE HAVING (1) A FREE CAO/SIO2 MOLE RATIO OF ABOVE ABOUT 1.70:1, (2) A TOTAL CAO/SIO2 MOLE RATIO OF ABOUT 3:1, (3) LIME IN SUFFICIENT AMOUNTS TO YEILD A CAO CONTENT IN THE FINAL CLINKER PRODUCT OF ABOUT 62 TO 68% BY WEIGHT OF THE CLINKER AND (4) ALUMINA IN AMOUNTS TO GIVE A TOTA ALIO3 CONTENT IN THE FINAL CLINKER PRODUCT OF ABOUT 3 TO 9% BY WEIGHT OF THE CLINKER, (D) COMPACTING SAID MIXTURE TO FORM DISCRETE PARTICLES, (E) HEATING SAID COMPACTED PARTICLES IN A HEATING ZONE AT TEMPERATURE OF ABOUT 1050*C. TO ABOUT 1500*C. IN THE PRESENCE OF STEAM, WHEREBY FLUORIDE VALUES ARE REMOVED, (F) ADDING CARBON TO SAID DEFLUORINATED COMPACTED PARTICLES IN AT LEAST STOICHIOMETRIC QUANTITIES TO REDUCE THE PHOSPHORUS VALUES PRESENT IN THE COMPACTED PARTICLES, (G) PASSING SAID CARBON-CONTAINING COMPACTED PARTICLES INTO A HEATING ZONE AND HEATING SAID PARTICLES INTO A HEATING ZONE AND HEATING SAID PARTICLES TO FROM ABOUT 1200*C. TO 1500*C. WHEREBY CARBON MONOXIDE AND ELEMENTAL PHOSPHORUS ARE EVOLVED, (H) RECOVERING THE PHOSPHORUS THUS EVOLVED, AND (I) RECOVERING A CEMENT CLINKER HAVING A TOTAL CAO/SIO2 MOLE RATIO OF ABOUT 3:1.
