pollution of fresh water sources. There are various types of mining activities in. Namibia, including mining of heavy metals such as copper, lead, uranium and zinc. Uranium is mined in the west of Namibia, whereas lead and zinc are mined in the southern parts of the country. Copper is being mined in the Tsumeb area where.
Assessment of the economic potential of lead-rich sulphide ore deposits follows techniques originally presented by Dr Brian Gulson. These techniques have been extended for use with lead-poor sulphide mineralisation e.g. gold occurrences and Cu-Ni sulphide occurrences. In all cases, the technique is most appropriate.
