| Abstract: | One-step defluorination technology in the preparation of feed-grade dicalcium Phosphate from triple superphosphate was introduced. Under the optimal process, the feed-grade dicalcium phosphate could be produced by neutralization of the leach liquor with calcium hydroxide solution, filtration and then dryness. The process fully utilized water-soluble calcium ion and decreased consumption of material and preparation. |
