Environmental impacts of mining in Zambia. Towards

2014-8-4  Environmental impacts from mining operations are significant and quite often severe, especially in developing nations which lack adequate management of the sector. In Zambia, impacts from mining results from both historical and ongoing mining operations, and the majority of them is located in the Copperbelt district. Recent investments in exploration and mine developments have, however, led to new operations also in other provinces. The main environmental problems associated with mines in Zambia are pollution of air, soil and water, geotechnical issues and land degradation. The contribution from old mining legacy sites have shown to be minor compared to current mining
