• Gersdorffite - Wikipedia

    en.wikipedia.org/wiki/Gersdorffite Gersdorffite is a nickel arsenic sulfide mineral with formula NiAsS. It crystallizes in the isometric system showing diploidal symmetry. It occurs as euhedral to massive opaque, metallic grey-black to silver white forms. Gersdorffite belongs to a solid solution series with cobaltite, CoAsS. Antimony freely substitutes also leading to ullmannite, NiSbS.It has a Mohs hardness of 5.5 and a ...

  • GERSDORFFITE (Nickel Arsenic Sulfide)

    www.galleries.com/Gersdorffite Gersdorffite, which is named for Johann von Gersdorff, the owner of the mine at which it was found, is a very uncommon nickel mineral that belongs to the Cobaltite Group of minerals. Most members of this group are rare to extremely rare except for cobaltite. Like other members of this group, gersdorffite can form nice crystals that are either cubic, octahedral, tetrahedral or even pyritohedral ...

  • Sulfuric Acid Leaching of Smelter Matte

    www.911metallurgist.com/sulfuric-acid-leaching Sulfuric acid leaching of lead smelter mattes resulted in the recovery of about 45 pct of the nickel and cobalt and 10 to 45 pct of the copper. The addition of manganese dioxide increased the cobalt and nickel recovery from 45 pct to greater than 90 pct, and increased the copper from 10 to 45 pct to nearly 100 pct recovery.
