本文介绍阿尔及利亚西北部的Deglen铅-锌氧化矿的选矿试验结果。 为了富集该矿石,进行丁脱泥和不脱泥选择性浮选铅-锌矿的试验,试验中采用椰油胺作为捕收剂。 该工作结果表明,没有必要采用双旋流洗选,因为此法获得的金属回收率相当低。 从总体上看,不脱泥浮选得到的工艺结果比脱泥浮选得到的工艺结果要好。 This article presents the beneficiation results of the Deglen lead-zinc oxide ore in northwestern Algeria. In order to enrich the ores, tests were carried out for the selective flotation of lead-zinc ore with butterfat and non-desliming, using cocamine as the collector. The result of this work shows that it is not necessary to use double swirling wash because the recovery of metal obtained by this method is rather low. Overall, the process results obtained without flotation are better than those obtained with desliming flotation.
