Abstract In general, the industrial flowsheets for the beneficiation of itabirite iron ores from the Quadrilatero Ferrifero (Minas Gerais state) in Brazil involves grinding, desliming, magnetic separation and cationic reverse flotation using both mechanical and columns flotation cells. At Brazilian plants, it is estimated that Fe losses generated at the slimes stage range between 8% reaching values higher than 20%. Slimes generated at hydrocyclone containing particle sizes of approximately 99% 10 μm, 45%

使用铁矿泥柱浮选提高铁的回收率

摘要 一般而言，巴西 Quadrilatero Ferrifero（米纳斯吉拉斯州）的板条石铁矿石的选矿工业流程包括使用机械和柱浮选槽的研磨、脱泥、磁选和阳离子反浮选。在巴西工厂，估计在煤泥阶段产生的铁损失在 8% 之间，达到高于 20% 的值。水力旋流器产生的泥浆含有约 99% 的粒径 10 μm, 45%
