本文介绍采用本课题组研制成功的酸化油类型助滤剂应用于铁精矿过滤时,药剂用量及过滤条件各参数对滤饼水分影响的规律性,并对加药与不加药过滤的不同结果进行了比较。结果表明,加药过滤比不加药过滤优越,它可在较低的矿浆浓度、温度和真空度的过滤条件下,获得滤饼水分较低而过滤效率较高的良好结果,为酸化油助滤剂的工业应用提供了技术依据。 This article introduces the regularity of the effect of the parameters of the dosage and the parameters of the filter on the moisture content of the filter cake when the acidified oil filter aid successfully developed by our group is applied to the filtration of iron concentrate, The results were compared. The results showed that the dosing filtration was better than that without dosing, which could obtain good results of lower filtration rate and higher filtration efficiency under lower filtration conditions of pulp concentration, temperature and vacuum. Technical application of the filter provided the technical basis.
