| Abstract: | Mineral processing experiments were conducted with a lean calcareous-magnesium collophane ore from Guizhou with P2O5 grade of 11.68% and MgO grade of 10.87%. Adopting a closed-circuit flowsheet consisting sequentially of a direct flotation and a reverse flotation with one roughing and two scavenging stages, a phosphorus concentrate with P2O5 grade of 28.04%, MgO content of 0.75% and P2O5 recovery of 81.92% was obtained. |
