  • 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.

    Mixed oxide and sulfide copper ores are leached following the same process stages as in Figure 4. Also, some sulfidic ores that are too lean to treat by flotation are also leached in heaps or dumps.
