    What is Sulfide Mining? | Mining Action Group

    Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water ...

    Sep 04, 2015 · It all depends on your sulfide product - what you have to leach. Leaching works poorly on coarser gold - it just takes forever to dissolve. Some types of sulfides react badly with leach systems, destroying the leach chemicals. If you have significant silver in your ore, many non-cyanide leach systems dont recover silver.
