浮选

Differences of wettability and floatability between diaspore and aluminium silicate minerals are due to the differences of crystal structure between diaspore and aluminium silicate minerals, and of the part Al-O, Si-O bonds, and the metal ions on the surface of the minerals.

一水硬铝石与铝硅酸盐脉石矿物晶体结构的差异、表面断裂的Al-O和Si-O键及表面离子活性区的差别，可影响矿物表面的润湿性与可浮性，类质同象及各种晶格杂质离子也将影响浮选剂与矿物表面的相互作用和矿物可磨性。

Adding the floatation agent not only can get better floatation result, but also can reduce the response time to flocculate, which play an important role in project on reducing capital expenditure、 energy consumption and the expenses on operation .

而浮选剂的投加不仅能获得更好的气浮效果，而且能缩短絮凝反应时间，这对实际工程中减少基建投资、能耗及运行费用有重要的意义。

A new process of which flotation is carried out while simultaneously the grinding is presented.

提出了边磨边浮创新思想，提供了一种在磨矿过程中对矿石进行浮选的新工艺。

The flotation behavior of pyrrhotite was investigated by using sodium diethyldithiocarbamate as a collector.

考察了乙硫氮为捕收剂时磁黄铁矿的浮选行为，发现在pH2-12的范围内，磁黄铁矿均可表现良好的可浮性。

The depressive behavior of (NH4)2 SiF6 on iron-containing silicate gangue, aegirine, in hematite flotation with sodium oleate as collector was studied.

研究了油酸钠为捕收剂的赤铁矿浮选中，水玻璃与氟化物等抑制剂对含铁矽酸盐脉石矿物霓石(NaFe2 SiO6)的浮选抑制行为。

In the pH range of 6~12, the results of the flotation tests indicate that the performance of the new combined cationic collector (CS3:CS1=3) and (CS3:CS2=2) is similar, and they are effective collectors for reverse flotation of the iron ores. The combined cationic collectors exhibited the same collectability as dodecylamine, but better selectivity than dodecylamine. By using the combined collector, the dosage of the collector decreased from 1 10-4mol/L to 1 x 10-5mol/L .

单矿物可浮性试验结果表明，在pH=6～12的范围内，新型组合药剂CS_3：CS_1=3和CS_3：CS_2=2具有相近的药剂性能，在其捕收能力与十二胺相当的前提下，不但选择性较十二胺好，而且还能显著提高药剂的协同效应，使药量从单用时的1×10~(-4)4mol／L降至1×10~(-5)mol／L，是铁矿石反浮选的高效捕收剂。

Because collophanite usually combines with dolomite, and their flotability is similar so that they can not be separated by the conventional flotation method.

由于胶磷矿多含有白云石且两者可浮性相近，因此运用浮选方法一直没能很好地解决胶磷矿中自云石的分离问题。

Essentially a float tube is a floatation device that is equipped with a seat.

基本上是浮管浮选装置中装有一个座位。

The study of coal wetting heat effect, zeta protential and adsorption of frother on coal/water showed that the frother is of collecting performance again.

研究表明，煤炭浮选非极性捕收剂对起泡剂的起泡性能具有显著的影响，具体效果与化学组成、浓度及配比有关，这一点对于煤炭浮选用药具有重要的意义。

Using diesel and paraffin chloride as disperse phase, the hydrophobic polymeric flocculant as flocculating agent, adding wetting reversed agent and frother to disperse phase, mixing those materials, the flotation agent, which is used to disposal oily waste water effectively is obtained.

用合成出来的疏水性高分子絮凝剂与表面活性剂（包括润湿反转剂和起泡剂），以及0#柴油和氯化石蜡-52复配叶轮气浮用浮选剂。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
