我厂是一个处理氧化铜矿的浮选厂,最终精矿采用浓密——过滤——干燥三段脱水流程.由于原矿含泥量较大,浮选工艺要求对矿石进行细磨,所以精矿产品中难以沉降的-10μ级别一般都高达37-40%,造成了精矿脱水的困难.加之浮选泡沫发粘,须大量冲水才能顺利输送,更增大了进入浓密机的矿浆量.因此,每当原矿含泥量大、处理量高时,现有的一台φ24米浓密机就产生过负荷,沉降时间不足,发
I plant is a flotation plant dealing with copper oxide, the final concentrate using dense - filtration - drying three paragraphs dehydration process. Due to the larger ore containing ore, flotation process requires fine grinding ore, so concentrate -10μ level difficult to settle in the product are generally as high as 37-40%, resulting in the difficulty of dehydration concentrate, combined with flotation foam sticky, a large number of flushing to be smooth delivery, but also increased the amount of pulp into the thickener. Therefore, whenever the ore contains a large amount of mud and a high throughput, an existing φ24-meter thickener generates overload and has insufficient settling time
