提炼矿石的工厂通常不是设在开采矿石的国家，而是设在其它国家。 - Plants which refine crude ores are often located in countries other than those in which the crude ores are mined
这些能够富集原矿石的植物通常是生长在乡村而非在那些原矿石所被开采的地方 - When the crude ore contains copper 1 . 84 % , the technical indexes such as the grade of copper concentrate 22 . 37 % and the recovery 78 . 70 % are obtained by use of single - stage grinding , one time of roughing , three times of scavenging and two times of cleaning
当原矿含铜1 . 84 %时，经过一段磨矿、一次粗选、三次扫选和二次精选，获得铜精矿品位22 . 37 % 、铜回收率78 . 70 %的技术指标。 - Abstract : the original mineral of dading iron mine was processed by the technique which included pre - classification , dry magnetic separation to discard dirt , magnetic separation of the coarsely ground ore , scondary grinding and secondary magntic separation of the rougher concentrate , thus raising the processing quantity of the crude ore , reducing the grinding cost , with the grade of iron concentrate 65 . 54 % , the recovery of iron 94 . 11 %
文摘:采用预先分级、干式磁选抛废、粗磨磁选、粗精矿再磨再磁选的工艺流程处理大顶铁矿原生矿，提高了原矿处理量，降低了磨矿成本，获得铁精矿品位65 . 54 、铁回收率94 . 11的技术指标
