direct and reverse floatation
Examples with "direct and reverse floatation" and their translation in Chinees
Direct and reverse floatation is a proper process of floatation for the rock. However in reverse floatation only H3PO4 may be added as a regulator and inhibitor, not H2SO4.
正反浮选是该矿石适宜的选矿工艺，在反浮选只能添加磷酸作为调整剂和抑制剂，不能添加硫酸。
In heated direct and reverse floatation, concentrate grade still fails to reach 30%. The ore dressing efficiency does not increase much in direct floatation with addition of a carbonate inhibitor NO-2. Hence in subsequent tests no heating is provided nor NO-2. But from the test result we find that addition of H3PO4 in reverse floatation may increase concentrate grades.
通过加温正反浮选，精矿的品位也没有达到30%，正浮选加温同时添加碳酸盐抑制剂NO-2，选矿效率提高的幅度不大，所以以后的试验没有加温也没有添加NO-2。

As the phosphorite contains both carbonate and silicate minerals, neither single direct floatation nor single reverse floatation can obtain a good floatation index.
由于该磷矿既含碳酸盐矿物，也含硅酸矿物，因此单一正浮选或者单一的反浮选较难获得较好的选矿指标。
From the above researches it is found that neither direct floatation nor single reverse floatation can achieve a concentrate grade of more than 30%. As the content of carbonate in the rock is fairly high, the combination of floatation and roasting digestion is investigated. Concentrate of direct floatation is roasted under different high temperatures for two to three hours and then cooled down. Then some water is added in to mix with and assimilate the concentrate. After that the concentrate is filtered and its grade analyzed.
通过上述的研究可以看出，直接浮选与单一反浮选都难使精矿品位达到30%以上，由于该矿的碳酸盐含量较高，采用浮选与焙烧消化相结合进行了研究，将直接浮选的精矿置于不同高温下进行焙烧两三个小时，冷却后，加入一定量的水搅拌消化过滤分析其品位。
