攀钢密地选矿厂尾矿高浓度输送

Conveyance of high-concentration tailings in Pangang's Midi Dressing Plant

密地选矿厂根据直径５３ ｍ浓缩机底流排矿浓度低、尾矿入坝率低的情况，在尾矿浓缩制备和输送系统进行了一系列的改造，尾矿输送浓度由１６％提高到３５％～４０％．

To cope with the problems in Midi Dressing Plant where 53-meter-in-diameter thickeners produced low-concentration tailings from their bottom discharges, and low tailing inflow to the tailing dam, a series of innovation on the systems of tailing thickening prepara-tion and conveyance have been conducted, resulting in the conveyed tailings' concentration as high as 35%~40% from the previous 16%.
