    Silver(Ag)

    After the repetitive processing of the electric and electronic scraps, sludge, paste, process sludge, waste film, oxidized silver cell, and, other scrap or waste containing the silver, the silver product with the purity of 99.99% or more is produced in the form of granule or ingot. This kind of silver is used for jewelry, electrode of solar cell, coating, catalyst or other various industrial purposes.
