| Abstract: | Experimental study on mineral processing technology of a carbonaceous phosphate rock from Western Hunan was conducted. The P2O5, MgO, SiO2 and S contents in this raw rock are about 20%, 6.70%, 11.81% and 2.93%, respectively. By adopting a reverse flotation flowsheet comprising sequentially decarburization, desulfurization, demagnetization processes at ambient temperature, a phosphorus concentrate with P2O5 grade and recovery of 28.19% and 78.47%, respectively, is obtained, through which the phosphate rock can be effectively enriched and reclaimed. |
