Korea CMK CO.,ltd.(shanghai office)

we are looking for Exotic Metal Scrap : Cobalt(cobalt foil,cobalt ash after bettery burning), Tungsten(drills,mills,cutters), Lithum etc.
    The content of metal is not fixed, for certain material they have certain content.  For example, COBALT FOIL: they are disassembled from mobilephone battery, sticked on ALUMINIUM FOIL inside; COBALT ASH:  after mobilephone battery burned. Now are buying them from KOREA and JAPAN.And also other material with COBALT ELEMENT. We use them for furnace refining to get high purity cobalt metal ingot. So generally speaking, we can accept any cobalt scrap, but the best we prefer is COBALT FOIL.
Also we deal with tungsten and lithum scrap with any content. If you can, please feel free to contact me at any time. THANK YOU!
    Waiting for your reply!
