This paper describes the results of study using CMC(Carboxyl Methyl Cellu- lose)for separation of bulk lead-zinc concentrates.Research work with two diffe- rent lead-zinc sulphide ores showed that both obtained satisfactory effects.In the circuit of lead-zinc separation,the recoveries of lead and zinc reached above 95% respectively. The investigation of some factors affecting lead-zinc separation showed that the efficiency of separation was the highest in the alkaline pulp(pH>10),and dif- ferent types of CMC...

This paper describes the results of study using CMC(Carboxyl Methyl Cellu- lose)for separation of bulk lead-zinc concentrates.Research work with two diffe- rent lead-zinc sulphide ores showed that both obtained satisfactory effects.In the circuit of lead-zinc separation,the recoveries of lead and zinc reached above 95% respectively. The investigation of some factors affecting lead-zinc separation showed that the efficiency of separation was the highest in the alkaline pulp(pH>10),and dif- ferent types of CMC obtained the same results.The separation became favour- able in the presence of calcium and copper ions in pulp.

本文叙述使用 CMC 分离铅锌混合精矿的研究结果。对两个不同类型的硫化铅锌矿研究表明,使用 CMC 均取得了良好的效果。在铅锌分离作业中,铅锌的回收率均超过95%。研究铅锌分离的某些因素表明:在碱性矿浆中(pH 值>10)分离效果最好;各种牌号的CMC 得到同样的结果;矿浆中有一定数量的钙离子、铜离子时,对浮选分离是有利的。

This paper describes the research work and production practice of separation of a lead-zinc sulphide ore by electroflotation. The ore treated was a polymetallic sulphide ore.The ore contained 2% Pb,4% Zn and a certain amount of pyrite,the principal minerals being galena,sphalerite and pyrite.Galena amounted to 80% in minus 0.06 mm size fraction,dissoluting pyrite and sphalerite. The plant adopted a differential flotation flowsheet to treat this type of ore before the use of electroflotation.The metallurgical...

This paper describes the research work and production practice of separation of a lead-zinc sulphide ore by electroflotation. The ore treated was a polymetallic sulphide ore.The ore contained 2% Pb,4% Zn and a certain amount of pyrite,the principal minerals being galena,sphalerite and pyrite.Galena amounted to 80% in minus 0.06 mm size fraction,dissoluting pyrite and sphalerite. The plant adopted a differential flotation flowsheet to treat this type of ore before the use of electroflotation.The metallurgical results achieved were as follows: the grade of lead concentrate 45.64%(as pyrite contained a certain amount of gold and no separation was made,thus having a low grade of lead concentrate),lead recovery 82.81%;zinc concentrate assaying 59.98%,and recovery 81.88%. Flotation research by means of several types of electrodes showed that the lead- zinc complex mineral was separated successfully through the depression on zinc mineral,without the use of regulators,depressants and other reagents.The effect of copper-carbon electrode was better,zinc-carbon electrode being second.Electroflotation could also be used for separating copper-sulfur(pyrite)bulk concentrate.The bulk concentrate contained lead from 29.47% to 32.56%.The content of the lead concen- trate after separation was between 54.60% and 57.06%,the lead recovery being up to 97-98%. The flowsheet of differential flotation by use of zinc-carbon electrode at a plant has brought about good results in treating the above ore.The lead concentrate grade increased to 41.33%(no separation of pyrite;if separated,60% could be obtained), with a recovery of 87.29%;zinc concentrate containing 59.85% Zn,with a recovery of 83.28%. The above results show that the electroflotation method is effective in separating the lead-zinc mineral.The metallurgical results achieved are equal to or slightly hi- gher than those by using flotation reagents.Sodium carbonate,sodium sulphite,zinc sulphate and other reagents can be saved.The amounts of xanthate and copper su- lphate can be reduced by 35% and 60% respectively.The electroflotation technique is of benefit to a plant.

本文介绍了采用通电浮选实现铅锌硫化矿石的研究和实际应用结果。工业实践表明,应用通电浮选可使铅锌矿物有效分选,获得良好的技术经济效果。

Chongqing Smelter is one of the earliest plants which began the production of electroreflned nickel.

Chongqing Smelter is one of the earliest plants which began the production of electroreflned nickel. Through more than twenty years' production practice and constant improvement of the technological flowsheet, the production of electroreflned nickel is five times of that of early sixties now.At present, the chief raw material to the Smelter is high nickel matte and pyrometallurgical process is adopted to manufacture nickel sulphide anode. The anode is electrorefined by the diaphragm direct electrolysis technique and electroreflned nickel with a purity of 99.99% is produced. As to the purification of electrolyte, the copper is removed with hydrogen sulphide in pipelines, the iron, cobalt and lead are removed by oxidation with chlorine gas and the residual lead, zinc and copper are removed by ion-exchange with resins so that the needs of producing high-quality electrorefined nickel can be met satisfactorily.

重庆冶炼厂是我国最早生产电镍的厂家之一,经过20多年的生产实践和不断改进工艺流程,使电镍产量较六十年代初期提高了四倍。 当前,重庆冶炼厂以高冰镍为原料,采用火法制取硫化镍阳极,硫化镍阳极隔膜直接电解生产纯度达99.99%的电镍。电解液净化采用H_2S管道反应脱铜、氯气氧化除铁钴铅、树脂交换法脱除残余铅锌铜的工艺,可满足生产高质量电镍的要求。
