摘要
东鞍山铁矿石的矿石类型及铁矿物种类多,矿物嵌布粒度细,矿泥量大,阴离子碱性正浮选流程不能适应矿石性质的变化。脱泥-反浮选流程适应东鞍山铁矿石的特性,通过对关键技术的研究,可在常规磨矿细度(-0.075mm占85%)下实现脱泥-反浮选工艺。工业分流试验表明,对于正常矿石,可获得铁品位63.66%,回收率80.13%的铁精矿;对于难选矿石,铁精矿品位62.83%,回收率75.48%。
The Donganshan iron ore is characterized by a variety of ores and iron minerals,finely disseminated size and large amount of slime. Therefore,the flowsheet of anionic alkalineflotation is not adaptable to variation in the ore properties. The desliming-reverse flotationflowsheet is compatible with the characteristics of the ore. The study on its key techniques showsthat desliming-reverse flotation can be achieved at normal grind(85%minus 200 mesh).Inindustrial test of partial flow, for normal ore ,concentrate containing 63.66%Fe can be obtainedwith a recovery of 80.13%and for refractory iron ore, concentrate containing 62.83%Fe can beobtained with a recovery of 75.48%。
