Zeta potential analysis shows that with the presence of Cu2+,the adsorption of xanthate anion on the surface of ma...

通过动电位分析表明，甘油基黄原酸钠在有Cu2+存在条件下不能阻止丁黄药的阴离子在铁闪锌矿表面的吸附，但能阻止丁黄药的阴离子在黄铁矿表面的吸附，与浮选结果一致。

And these results of some main conditions from carrier flotation have been compared, the results show that the recovery of fine grained gold have been increased by applying sulphonating kerosene as a subsidiary collector,at the same time, it also decrease the consumptions of xanthate and No.

对某高泥化高氧化铁锰黑土矿中的金进行了试验研究，试验采用黄铁矿作为载体有效回收了黑土矿中的金，并对载体浮选的几个主要条件进行了对比，结果表明用磺化煤油作辅助捕收剂可增加细粒金的回收，同时也降低了黄药和2#油的用

And, we also discussed the mechanisms of flotation and leaching of the tow zinc oxide ores.

In the tests, the nonionic type polyacrylamide, the anion type polyacrylamide and the zwitterion type polyacrylamide, and the compounding of the poly-aluminum chloride/PHP and the calcium chloride (CaCl2)/NPAM were used as flocculation agents.

选择聚合氯化铝/阴离子型聚丙烯酰胺、氯化钙（CaCl2）/非离子型聚丙烯酰胺组合与NPAM、PHP、两性离子型聚丙烯酰胺作为絮凝剂，在对道清选煤厂水采筛下原生煤泥和浮选尾矿的煤泥水进行组合药剂絮凝实验的基础上，考察了pH对煤泥水絮凝沉降的影响。

It demonstrated that the hydroxy organic acids substituted with-OH,-SH at α—C such as lactic acid, Hydroxy-acetic acid, mercapto-acetic acid, glyconic acid have good selectivity for separation of hematite and aegirine pka values of organic acids fall down because of the-I inductive effect of-OH or-SH, and lie at the pH range between two minerals point-zero-charge. As a result, the depression ability of them was enhanced, and a cyclo-pentyl chelate was formed when this organic acids acted with Fe〓 on the minerals surface.

发现在α位具有-OH、-SH等取代基的短链一元羧酸（乳酸、羟基乙酸、巯基乙酸，葡萄糖酸）对赤铁矿与钠辉石的浮选分离具有优良的选择性抑制作用，-OH、-SH的-I诱导效应导致有机酸的pKa值下降并落在两种矿物零电点之间，使其抑制性能增强，并与矿物表面的Fe〓形成稳定的五元螯合环。

The experiment was in progress in dyadic foam of intermittence flotation tower,to the positive ion type,the negative ion type,type and amphiprotic type,etc.

结果：泡沫浮选法去除废水中铬离子的表面活性剂，阳离子型和非离子型表面活性剂效果最差，阴离子表面活性剂效果最好。

It is shown that mixed tolyl arsonic acid was much superior to either para- or ortho-isomer alone for cassiterite flotation.

当混合比为45：55时，锡石产率出现&峰值&，可得到较高的浮选指标。

On the bais of investigation of basic chracteristics of lithotypes. Flotation and selective grinding were used to separate macerals in the coals.
