| Abstract: | Laboratory study was carried out to process a siliceous-calcareous cellophane ore from Guizhou province with a double-reverse flotation technique. It is found that at the grinding fineness of -74 μm 82.50%, with YW-01 and sulfuric acid as collector and regulator respectively for roughing at the optimized dosage of 1.4 kg/t and 14 kg/t, with SEA as collector for cleaning at the dosage of 0.5 kg/t, a closed-circuit test with the process consisting of one roughing, one cleaning and one scavenging resulted in a phosphate concentrate with P2O5 content of 30.54% at recovery of 88.59%, and with contents of MgO and SiO2 at 0.81% and 12.28%, respectively. |
