Production of fluid fertilizer from phosphorus furnace waste stream

摘要: Processes and compositions of matter are disclosed for the production liquid fertilizers wherein wastewater from a phosphorus smelting furnace is incorporated in fertilizer processes. The replaces water evaporated dissolves salts. A serious pollution problem avoided when fertilizers. invention discloses process making orthophosphate suspension impure phosphoric acid neutralized condensing system, system bled off, suspending clay added to produce fertilizer. In this process, sludge made at furnaces used fertilizer, phosphate recovered. New disclosed. with low impurities content burned make orthophosphoric recycled an agglomerating step elemental phosphorus.
