Thisthesis describes a new metallurgical process-oxidation-dry distillation pro-cess, which might be used for the treatment of such concentrate. The firststep of the process was to treat the concentrate to produce volative metalchlorides, residue and leached solution. Secondly, by use of various generalprocesses the intermediate products might be treated to extract antimo...             广西大厂脆硫锑铅矿精矿是一种难处理的复杂硫化矿。本文叙述了处理这种精矿的一种新方法——氧化干馏法。先用该法处理精矿,产出挥发性金属氯化物,浸出残渣和浸出液;再用一般方法处理中间产物,以提取锑和铅回收银、铟、硫等有价伴生元素,并再生氯化铁。本文还用渐次气化-图解切线法研究了氧化干馏体系及浓三氯化锑溶液分馏脱砷体系的气-液相平衡问题。 文摘来源          Because recovery of associated valuable elements from tailings of tungsten mine had little been researched before 1980s', the loss and its reasons of the associated valuable elements in the ore dressing process were analyzed. The ways of increasing comprehensive recovery effeciency are recommended. The ways include:choosing vein zwither and mica crystal block in roughing; getting more middlings and decreasing the grade of rough concentrate in gravity concentration; spread...             针对８０年代以前钨矿山对排入尾矿中的伴生有价元素的综合回收研究较少，本文分析了伴生有价元素在选矿流程中的损失情况和原因，指出了提高综合回收率的途径：在粗选工段应拣回脉壁云英岩和云母晶簇块；在重选工段应多接取一些中矿、降低粗精矿品位；细泥处理应加强硫化矿的浮选回收；推广选、冶联合工艺和分支串流浮选工艺在处理低品位尾矿中的应用等。从而为加强综合回收、提高选厂经济效益，以推动对库存尾矿的再开发利用。 文摘来源   << 更多相关文摘         相关查询: valuable elements associated elements associated elements) elements gold and associated elements associated elements in coals valuable associated effect of elements existing forms of associated elements modes of occurrence of associated elements gold and its associated elements  对查询结果不满意
