upon floatation
Tradução de "upon floatation" em chinês
对浮选
Inhibitor NO-2 is a strong dispersant and inhibitor. Its dosage test is carried out after determination of dosages of other reagents. At the same time, during the test, effect of sifting sodium hexameta phosphate upon floatation is also studied. The test flow is shown in Figure 5-4 and test result in Table 5-4.
抑制剂NO-2是较强的分散剂和抑制剂，确定其他药剂的用量之后进行了其用量试验，同时试验过程中研究了精选六偏磷酸钠对浮选的影响，试验的流程图5-4，试验结果见表5-4。
In the above research, the inhibitor NO-2 is organic with strong dispersing capability. Besides, to function fully, the phosphorite middling slurry has to be in a comparatively high temperature, which leads to a higher cost of floatation. Hence in order to study effects of inorganic dispersant sodium hexameta phosphate upon floatation, as its inhibiting capability is quite strong, its dosage should be small. Apart from this, 9.0 kg/t sodium silicate is added into the direct floatation roughing. So no such reagent is added into the roughing but into fineness of direct dosage is 0.2 kg/t. When the dosage increases to 0.3 kg/t, no foam will appear in the fineness. This indicates that the dosage is quite large.
在上述研究中抑制剂NO-2是一种有机抑制剂有较强的分散性且用于磷矿选矿中矿浆的温度较高，才能体现该药剂的性能，导致选矿成本较好，为此，研究了无机分散剂六偏磷酸钠对浮选的影响，由于该药剂的抑制性较强，用量宜小，且在正浮选粗选中添加了9.0kg/t的水玻璃，因此在粗选中没有添加该药剂，而是添加到正浮选的精选中，用量为0.2kg/t，用量增至0.3kg/t时，导致精选不产生泡沫，说明用量较大。
As in the above researches it is quite hard to raise concentrate grade, heating is applied to carry out heated the heated floatation, effect of the carbonate mineral inhibitor NO-2 upon floatation is studied; a test of reverse floatation is done with addition of H2SO4 or H3PO4 to floated concentrate.
由于在上述研究中，精矿品位较难提高，因此，进行加温浮选，在此次加温浮选中研究了碳酸盐矿物抑制剂NO-2的用量对浮选的影响；在浮选精矿添加了硫酸或磷酸进行反浮选探索研究。
