• Sulfide Minerals an overview ScienceDirect Topics

    The mined ore typically contains at least 60% sulfide minerals by volume, and therefore sulfur is the most important element by mass. The ore hosts range from entirely volcanic to entirely sedimentary, and so the deposits are also referred to as volcanic-hosted massive sulfides (VHMS) or sediment-hosted massive sulfides (SHMS).

    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, environment, and communities.
