捕收

This paper drawed lessons from the advanced techniques(Fenton oxidation, photocatalytic oxidation, photochemistry oxidation and microorganism-decomposing method)in water processing to study the degradation effect and regulation of the typical fatty amine flotation collectors in water body, which mainly aimed at decyl propyl ether amide, dodecyl propyl ether amide, laurylamine and stearamine.

本文借鉴水处理中的先进技术（Fenton试剂氧化法、光催化氧化法、光化学氧化法和生物法）来研究水体中典型脂肪胺浮选捕收剂的降解效果与规律，主要针对癸烷基丙基醚胺、十二烷基丙基醚胺、十二胺和十八胺。

The other was not exerting outside electric field and not adding redox reagents to control electropotential.

原生电位浮选工艺有两个要点：一是主要调节和控制包括矿浆pH值、捕收剂种类、用量及用法、浮选时间以及浮选流程结构等在内的传统浮选操作参数，二是不采用外加电极、不使用氧化—还原药剂调控电位，这两点为该工艺在现有浮选体系中实际应用及推广创造了条件。

本文研究了气/液界面上起泡剂的物化性质、混合起泡剂中起泡剂之间及起泡剂与捕收剂之间相互作用以及起泡剂在煤/水界面的性质。

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。

本文研究了气/液界面上起泡剂的物化性质、混合起泡剂中起泡剂之间及起泡剂与捕收剂之间相互作用以及起泡剂在煤/水界面的性质。

The electrochemistry and the mechanism of jamesonite, marmatite with collectors have not been reported and the study blazes new trails.

脆硫锑铅矿、铁闪锌矿的电化学及其与捕收剂相互作用的机理未见有报道，具有创新性。

The results show that jamesonite and pyrrhotite have good floatability in the pH range of 2-10 and marmatite has good floatability in the acid and it is difficult to separate these minerals. In the pH range of 6-8, the separation of jamesonite and pyrrhotite, marmatite is possible when using mercaptoacetic acid and mercaptoethanol as depressants. In case of the presence of Cu2+ ion, however, it is difficult to separate the three minerals. Infrared spectrum demonstrates that there are a number of function groups such as —SH,—COOH,—OH in the molecular structure of depressant.

结果表明：用丁黄药作捕收剂，脆硫锑铅矿和磁黄铁矿在pH 2~10范围内都有良好的可浮性，铁闪锌矿在酸性条件下可浮性好，三者分离困难；在pH 6~8之间，采用巯基乙酸和巯基乙醇作抑制剂，脆硫锑铅矿与磁黄铁矿和铁闪锌矿的分离是可能的；但铜离子存在时， 3种矿物之间的选择性分离是难以实现的。

Experiment about flotation characteristics of amesonite, marmatite and pyrrhppite are done. According to the result, we can select suitable collection and reagents to inhibit iron minerals .for the separation of lead Zinc minerals Small-scale experiments of flotation separation of lead and antimony minerals .

采集了脆硫锑铅矿、铁闪锌矿、磁黄铁矿等纯矿样，进行了这些纯矿物的一系列浮选性能试验，并以纯矿物的试验初步筛选铅锌浮选分离的组合捕收剂、硫化铁矿的抑制剂。

Using butyl-xanthate as collector, marmatite can be activated by Cu2+ with the presence of glyceryl-xanthate and then possesses good floatability,while pyrite can't be activated,therewith these two minerals can be separated.

结果表明，用丁黄药作捕收剂，在甘油基黄原酸钠存在下铁闪锌矿能被Cu2+活化从而具有良好的可浮性，而黄铁矿不能被Cu2+活化，从而实现两种矿物的选择性分离。

The marmatite has sulphur-induced flotability at neutral and weakly alkaline pulp.

在中性和弱碱性条件下，铁闪锌矿具有硫诱导无捕收剂浮选。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
