Sulfuric acid (H 2 SO 4, 95.0–98.0 wt%, VWR), nitric acid (HNO 3, 68.0–70.0 wt%, VWR), hydrochloric acid (HCl, 36.5–38.0 vol%, VWR), INTRODUCTION Dicalcium phosphate is the calcium phosphate with the formula CaHPO4. The "di" prefix in the common name arises because the formation of the HPO4 2– anion PRODUCTION OF DICALCIUM PHOSPHATE FROM LAO
These parameters were fixed at a leaching time of 16 min, stirring speed of 400 rpm, temperature of 25 oC, hydrochloric acid concentration of 5 % and process achieves around 70% phosphorus recovery as an industrial-grade (19 wt% P) dicalcium phosphate dihydrate product with minimal iron, magnesium, and aluminum Recovery and separation of phosphorus as dicalcium
In this study, we develop an integrated process for the direct recovery and separation of dicalcium phosphate dihydrate for fertilizer and livestock feed additive production from a low-grade (2.0 wt% P) iron-rich (19.7 wt% Fe) Simplified process flowsheet for gold production from ore by direct cupric chloride leaching in the compared scenarios and cases. The Reference process Direct Cupric Chloride Leaching of Gold from Refractory Sulfide Ore
In this study, we develop an integrated process for the direct recovery and separation of dicalcium phosphate dihydrate for fertilizer and livestock feed additive production from a low-grade (2.0 wt% P) iron-rich (19.7 wt% Fe) The production of Dicalcium phosphate from Lao Cai second grade apatite was investigated by leaching with dilute hydrochloric acid.
