For this,experimental study was made on a new process of potential-controlled preferential flotation in a sequency of copper,lead and zinc,which used LP-01 as collector for copper mineral,DDTC as collector for lead mineral,copper sulfate and butyl...

为此，以LP-01为铜矿物的捕收剂、乙硫氮为铅矿物的捕收剂、硫酸铜和丁黄药为锌矿物的活化剂和捕收剂、石灰为矿浆电位调整剂，并在选铜、铅时配合使用铅矿物的组合抑制剂ZnSO4+YN，对该多金属复杂硫化矿进行了电位调控铜、铅、锌依次优先浮选新工艺试验研究，获得了含铜21.74%、铜回收率62.31%的铜精矿，含铅61.23%、铅回收率55.07%的铅精矿和含锌56.43%、锌回收率90.02%的锌精矿。

The paper present the productive circumstances of recovering bismuthite from the magnetic dressing tailings of wolframite in Tieshanlong tungsten mine, point out the necessity of desulphurization before the floatation of bismuthite , and put forward the attentive matters in the floatation process.

介绍了铁山垅钨矿从黑钨磁选尾矿中回收泡铋矿的生产情况，指出了浮选泡铋矿之前脱净硫化矿物的必要性，并提出了生产操作中应注意的事项。

Studied the coordination chemical reaction of Fe、Co、Ni、Cu、Mg、Ca、Al with TC,OTC,CTC and the ternary association of Co-OTC、Ni-CTC with DAN,we found that the formation of new compounds improved significantly the hydrophilic properties of TCs,the TCs are transformed into hydrophobe from hydrophilic matter.

2研究了Fe、Co、Ni、Cu、Mg、Ca、Al与TC、OTC、CTC之间的配位化学反应和Co-OTC、Ni-CTC与DAN之间的三元缔合作用，发现新化合物的形成显著改善了TC、OTC、CTC的亲水性能，使其由亲水物质转变为疏水物质，有利于提高亲水有机溶剂气浮浮选体系对水样中痕量四环素类抗生素的测定灵敏度和分离/富集效率。

In the aqueous solution, Cu precipitates with ammonium thiocyanate and tetradecyl benzyl dimethylammonium chloride .

研究发现，在水溶液中Cu与硫氰酸铵、氯化十四烷基二甲基苄基铵形成不溶于水的三元缔合物，在少量氯化钠存在下此三元缔合物沉淀浮于水相上层并与水分成界面清晰的两相，分相过程中Cu被定量浮选。

The experiments include the flotaion of the different types of the Yinshan ores with different kinds of the flotation reagents and different flowsheets. The authors consider that for the flotaion of the lead and zinc ores, the necessity of using cyanides as depressants depends chiefly on the amounts of pyrite present and its ...

作者认为，对于那些黄铁矿含量少或黄铁矿易被抑制的铅锌矿石，采用优先浮选而不用氰化物作抑制剂是可行的，但对于那些含量大且可浮性好的黄铁矿的矿石，如果完全不用氰化物则要从药方与流程等来考虑。

Studies the distribution regular of sulphuring in course of 8~# coal flotation in Xiqu preparation plant,to provide test data for 8#coal flotation concentrate desulphuring.
