我们竞彩足球世界杯app只有一种，操作简单方便，用量少，不用脱泥、脱铁，可直接浮选。此种世界杯盘口进行浮选原矿品位在1.2以上时，浮选精矿品位5.5以上，尾矿品位0.3以下，回收率85%以上，此竞彩足球世界杯app也可在弱碱性进行浮选，效果没有太大的区别，竞彩足球世界杯app的使用范围比较宽泛。

      We use only one unique reagent, simple and convenient operation, less dosage, dehydration and deferrization is not necessary , can be directly flotation. When the grade of ROM  is above 1.2, the concentrate  is above 5.5, the tailing grade is below 0.3, and the recovery rate is above 85%. This collector can also be used in weak alkalinity flotation,but the effect is not too different. Use of the reagent is very wide.
