我不知道楼主是求助还是挑战?
在这个园地里应该说大家是以互相学习相互提高为目的,互相帮助是所有会员应尽义务.大家来自不同地方,有不同的专业,因为英语,大家走到这。翻译各专业的英文资料应该不是我们的目的,更不会有人在这方面来争强好胜。搂上两位的翻译就是最好的见证,可以看出他们是真心想帮忙的。
何以我会觉得楼主带有挑战的味道呢?
因为楼主挑来的这句话是英文专业论文摘要的中间一句,上不着天,下不着地,没有任何语境,不提供专业背景,让人翻译无从谈起。有累楼上两位了!由于没有上下文,两位的翻译与原意相距甚远,我相信凭你们的英语水平足以译好,当然要看我提供的摘要原文啦。
如果楼主是无心之失,那就怪我小肚鸡肠。版规上好象有要求,在为其他人提供帮助之后才可以请求帮助(我对版规了解不多,也许有出入),不赞成只索取不付出的做法。希望楼主多参与,在提出请求时,要为楼下的人提供足够的信息。

Abstract
Indium is an important by-product of zinc metal processing operations. Indium and other metal values are recovered during the production of primary commodities such as zinc by means of complex procedures, many of which are proprietary to each producer. One zinc recovery method consists of the Waelz process followed by leaching and purification prior to electrolytic recovery of zinc as cathodes and subsequent containment of the indium fraction in residues. Related processes for recovery of lead and tin from smelters and refineries also provide indium and other compounds. Indium may be associated with other valuable elements such as vanadium, thallium, gallium and germanium, and cadmium. Typical sulphide-bearing host minerals consist of Sphalerite, Galena, and Chalcopyrite. The igneous intrusions in sedimentary formations may include other base metals such as copper, cobalt, and noble metals consisting of gold, silver, and platinum group metals. The review serves to assimilate the major highlights of this somewhat rare metal which has both strategic importance and is well suited to electronic applications.On a global basis, the writers are aware of 30 producers dedicated to the commercial production of indium metal. Countries such as Belgium, Canada, China, France, Japan, Russia, and the USA are the largest producers of indium while about ten other countries contribute smaller quantities for worldwide consumption. The supply and demand of pure indium products during the past 40 years has been erratic and subject to wide fluctuations in delivered price. The paper describes the sources and established industrial processes for recovery of indium originating from sulphidic materials and process reverts.
