How To Separate Antimony Sulfide From Antimony Ore

  • Antimony Ore | MSquare Mining

    Antimony is a lustrous tin-white metal. Although it is usually described as a metal, it possesses mixed metallic and nonmetallic characteristics, and is more properly described as a semimetal or metalloid.The antimony ore found in our mine is Stibnite, which is a sulfide bearing ore and is concentrated using a froth flotation process.

  • How to Remove Arsenic, Antimony & Bismuth from Copper

    Arsenic, antimony and bismuth are more uniformly diffused in coarse metal than in the ore, where they occur in separate intermixed minerals. In coarse metal these elements probably exist entirely as sulphides, uniformly diffused through a comparatively large proportion of regulus, and their behavior under calcination differs notably from that .
