针对含贵金属 0 1 2 %的高冰镍磨浮磁选铜镍合金氯化浸出渣富集贵金属生产流程中的不足 ,提出了新的工艺流程结构 ,包括煤油脱除元素硫 -熔炼含贵金属高锍 -加压酸浸三个步骤 ,贱金属分离效率 ( % ) :Cu 99 5、Ni 99 8、Fe 94 5、S 99 6、SiO2 98 8;贵金属回收率 ( % ) :Pt 98 0、Pd 97 0、Au 97 0 ,产出贵金属品位 >30 % ,贵贱比 >1的精矿。
Aiming at the shortage of enriching precious metal production process of high nickel bearing nickel rich nickel containing leaching slag containing precious metal 0 1 2%, a new technological process structure was proposed, including the removal of elemental sulfur from kerosene - Pressurized acid leaching in three steps, base metal separation efficiency (%): Cu 99 5, Ni 99 8, Fe 94 5, S 99 6, SiO 2 98 8; Precious metal recovery (%): Pt 98 0, Pd 97 0 , Au 97 0, the output of precious metal grade> 30%, expensive> 1 concentrate.
