使用助滤剂的效果,除与助剂本身性能、加量有关外,还和许多其它因素有关,诸如过滤的方法、条件、助滤剂的加入方式、以及被处理物料的特性等等。故不能认为一种助滤剂,对于不同处理对象,或者同一处理对象不同作业条件下,都是等效的。本文介绍同一矿区贫富两种疏化镍矿石,分别浮选所得精矿,真空抽滤的试验情 The effect of using the filter aid is not only related to the performance and dosage of the additive, but also relates to many other factors such as the method and conditions of the filtration, the way of adding the filter aid, the characteristics of the material to be treated and the like. Therefore, it can not be considered that a filter aid is equivalent to different treatment targets or different working conditions of the same treatment target. This article describes the same mining area of ​​two kinds of nickel-rich nickel and nickel-rich ore flotation concentrate, vacuum suction filtration test
