Zambia orders Vedanta's Konkola to dispose of Chilean copper

LUSAKA, Sept 14 (Reuters) - Zambia’s environmental management authority on Monday ordered Konkola Copper Mines (KCM) owned by Vedanta Resources to dispose of copper concentrates it imported from Chile because they had high levels of arsenic, a toxic substance.

On June 25 Zambia asked KCM to delay the processing of copper concentrate it imported from Chile until it puts in place safety measures to avoid pollution, Zambia’s deputy minister of mines said.

Zambia’s environmental authority said KCM must submit a full programme for sending the material back to Chile or to other smelting facilities outside Zambia by Friday.

“KCM has been directed to immediately stop any plans to process the copper concentrates containing high levels of arsenic,” the agency said.

KCM was not immediately available to comment.

KCM had to import its first semi-processed copper from Chile to ensure its Nchanga smelter operates at full capacity.

The ministry of mines said in June that the level of arsenic in copper concentrates mined in Zambia was 1 percent but that the material imported from Chile had a level of around 4 percent.
