| 摘 要： | 通过矿物学研究查明了硫酸烧渣的矿物学性质。烧渣含铁为57.1%,杂质为石英、金云母、石膏等矿物;石英等矿物被包裹在三氧化二铁中,石膏填充在金属缝隙中或包裹在金属体外围。细颗粒间的团聚不利于磁选,通过重选摇床和阳离子反浮选脱硅联合工艺流程,显著提高铁精矿品位。铁总回收率大于85%。

| Abstract: | The mineralogical study identified the propertise of pyrite cinder. The cinder contains ferric oxide, quartz, mica, gypsum, TFe>57.1%. The impurities wrapped in ferric oxide. Gypsum filled in cracks and warpped outside the oxide iron. Reunion between the fine particles was not conducive to magnetic separation. Greater iron concentrate can be get by gravity separation and cationic reverse flotation separation. Total iron recovery rate was greater than 85%. |
