| Abstract: | Mineral processing technology for a high phosphorus-silicon oolitic iron ore from abroad was studied. Factors inducing separation difficulty were ascertained through analysis of ore properties, and a flowsheet was proposed including sequentially stage grinding, low intensity magnetic separation and reverse flotation for dephosphorization and desilication. Results showed that the recommended processing technique resulted in magnetite with 65.68% Fe grade and hematite with 55.58% Fe grade, with the total iron recovery at 78.92%. |
