    摘要： A process is disclosed for recovering elemental phosphorus from an aqueous sludge and converting the residue into non-hazardous waste. The sludge is separated into (1) a slurry of water containing suspended phosphorus and dirt particles and (2) coarse solids. A flocculating agent is added to the slurry to agglomerate the suspended phosphorus and dirt particles, which are recovered from the water and are heated to melt elemental phosphorus particles. A coalescing agent is added to coalesce the melted elemental phosphorus, which is separated from the dirt particles. The coarse solids are mixed with hot water to melt the phosphorus sludge, which is separated from inert solids. The solids are heated to burn any residual elemental phosphorus. The separated molten phosphorus sludge is stirred with a solution of chromic acid to recover the phosphorus as a separate phase. A reducing agent is added to the remaining water and solids to reduce the Cr+6 to Cr+3. Finally, an alkali is added to the water and solids to react the residual phosphorus and form phosphorous compounds. The reaction mass is filtered and the filter cake can be placed in a landfill as a non-hazardous waste.

    摘要： A method of recovering elementary phosphorus from an aqueous sludge containing about 1 to about 15 wt % dispersed particles of phosphorus is disclosed. To the sludge is added about 1 to about 20 wt %, based on the weight of the phosphorus present in said sludge, of a phosphate salt that has the general formula: where R is an alkali metal or ammonium and n is 0 to 30. The phosphorus in the sludge is melted and the solids in the sludge are separated from liquid phosphorus and water. Liquid phosphorus is then separated from the water.

    摘要： High purity phosphorus and phosphorus compounds are prepared by first reacting H.sub.3 PO.sub.4 with a lead compound such as PbO to form Pb.sub.3 (PO.sub.4).sub.2. The Pb.sub.3 (PO.sub.4).sub.2 is reduced with H.sub.2 at a temperature sufficient to form gaseous phosphorus which can be recovered as a high purity phosphorus product. Phosphorus compounds can be easily prepared by reacting the phosphorus product with gaseous reactants. For example, the phosphorus product is reacted with gaseous Cl.sub.2 to form PCl.sub.5. PCl.sub.5 is reduced to PCl.sub.3 by contacting it in the gaseous phase with solid elemental phosphorus. POCl.sub.3 can be prepared by contacting PCl.sub.5 in the gaseous phase with solid P.sub.2 O.sub.5. The general process is particularly suitable for the preparation of radiophosphorus compounds.

    摘要： A process for recovering phosphorus values from phosphorus sludge comprising (1) mixing the sludge with from about 1 to about 8 parts by weight carbon bisulfide per part by weight phosphorus sludge; (2) agitating the mixture to a Reynolds number value of from about 2 X 105 to about 1.0 X 106 for a period of from about 0.2 minute to about 16 minutes; (3) filtering the resulting mixture to remove particulate material and thereafter recovering the phosphorus value from the carbon bisulfide fraction.
