分银渣综合利用新工艺扩大试验

Enlarged Experiment on New Technolgy for Complex Utilization of Silver Separating Residue

提出了从分银渣中综合回收稀贵金属及杂项元素的新工艺 :先将贵金属金银与一些杂项元素 (如锑、铋、碲等 )分离 ,然后分别提取。金银回收率在 94%以上 ,锑、铋、碲回收率在 90 %以上。产品质量 :金银实集 30倍以上 ,三氧化二锑、二氧化碲、海绵铋的纯度分别达 98%、 96 %和 42

The presented new technology for complex recovery of rare metals,precious metals and other valuable elements is:at first,separate precious metals gold and silver with other elements such as antimony,bismuth,tellurium,etc;then extract them separately.The recovery of gold and silver is more than 94%,recovery of antimony bismuth and tellurium is more than 90%.Quality of products:gold and silver concentrated for more than 30 times,the purity of anti mony oxide,tellurium dioxide and sponge bismuth reaches more than 98%,96%and 42% respectively.
