    What Is Involved in Manganese Mining?

    26-11-2020· Manganese mining often requires a specific method of extraction, because nodules can be embedded among various other rock bed materials. One of the benefits to open-pit mining is reduced cost compared to other mining methods. The change in geologic configuration, however, means the environmental impact of this mining is often considered severe.

    Environmental Impacts of Nodule, Crust and Sulphide

    The mining process will disrupt this surface sediment layer and remove the nodules. Experiments have shown that species are very slow to return to the disrupted areas. Combined with the large areas that will need to be mined for manganese nodules, this gives rise to potentially a high environmental and ecological impact.
