Vedanta Resources will launch a copper treatment facility at its Zambia-based Konkola Copper Mine Nchanga unit to raise output.

The project involves the development of a granulated slag dump for treating copper concentrates from Nchanga, Konkola and other sources that are not operated directly by Konkola Copper Mine.

Under the smelting process, copper concentrate will be treated in an electric furnace with a flux.

The assessment report submitted to the Zambia Environmental Agency says the final products are matter and slag with the matter being further processed to generate copper anodes.

Project life is estimated at 20 years at an annual average slag production rate of 540,000t.

The Nchanga Mining Licence Area (LML34) comes under Konkola Copper Mine’s existing licence area.

Konkola Copper Mine aims to meet more than 50% of Zambia’s expected copper production by 2010 and meet rising demand from the global market.
