The Mineral GalleryThe Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or darkcolored streaks, and an igneous origin.
What is Sulfide Mining? | Mining Action GroupMetallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfiderich 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 ...
