single reverse floatation
Exemplos para "single reverse floatation"
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。
In single reverse floatation the concentrate grade is 23.88% at most. Therefore single reverse floatation is not desirable for concentration of calcareous rock.
采用单一反浮选该精矿的品位最高也只有23.88%，因此单一反浮选不适用钙磷矿的选矿。
As the rock has a fairly high content of carbonate, a single reverse floatation test is conducted.
由于该矿含碳酸盐矿物的量较高，因此，采用单一反浮选进行了试验。

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。
For calcareous phosphate rock, the technology of normal temperature direct-reverse flotation was applied, and meanwhile, the effect of single reverse flotation, direct flotation roasting and heating flotation for flotation was explored, and in normal temperature direct-reverse flotation, the effect of grinding fineness and various chemicals for ore dressing indexes was researched.
对于Calcareous rock钙质磷矿采用常温正反浮选工艺，同时探索了单一反浮选、正浮选焙烧以及加温浮选对浮选的影响，在常温正反浮选研究了磨矿细度、各种药剂对选矿指标的影响。
Based on the above test the grinding finenesses and dosages of direct floatation reagents including sodium carbonate, sodium silicate, and TSK-125 are determined and a test of H3PO4 dosage in reverse floatation is carried out.
通过上述的试验确定了磨矿细度、正浮选药剂碳酸钠、水玻璃、TSK-125的用量进行了反浮选磷酸用量试验。
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。
In reverse floatation, when H3PO4 dosage is the same, the ore dressing efficiency is the highest when H2SO4 dosage is 15.0 kg/t. When H3PO4 dosage is small, concentrate grade is relatively low. In the above test, no grade reaches above 30%.
反浮选中，在磷酸用量相同时，硫酸在15.0kg/t 选矿效率最高，磷酸用量较低时不利于精矿品位的提高，上述试验中精矿的品位都未提高到30%以上。
In accordance with nature of ores, different technologies may be applied. For silica phosphatic rock, the technology of single direct flotation or dense selection may be applied to improve concentrate grade and eliminate its silica gangue; for calcareous and magnesite phosphatic rock, single reverse flotation shall be chosen to remove calcareous and magnesite gangue; for complex phosphate mine, namely the mine containing both silicate gangue and carbonate gangue with different transitional types, the technology of direct-reverse flotation shall be chosen with different flotation technology emphasized; for transitional phosphate rock with high content of silicate, the focus is direct flotation technology, otherwise the focus is reverse flotation technology to remove carbonate or use double reverse flotation technology to eliminate impurity.
根据矿石的性质，可以采用不同的工艺，对于硅质磷块岩采用单一直接浮选或重选的工艺提高精矿的品位，剔除其硅质脉石矿物；对于钙、镁质磷块岩，选取单一的反浮选脱除钙、镁质脉石；对于复杂的磷矿也就是既含有硅酸盐脉石又含有碳酸盐脉石，且含量的不同过渡型的磷矿，采用正反浮选工艺，而强化的是不同浮选工艺，对于硅酸盐矿物含量较高的过渡型的磷矿，重点是正浮选工艺，反之强化反浮选工艺，脱除碳酸盐矿物，或采用双反浮选工艺，剔除杂质。
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。
