Vedanta's Zambian Copper unit announces major smelter overhaul to boost output

18 july 2025

Konkola Copper Mines (KCM), Vedanta Resources' Zambian subsidiary, has unveiled plans for a comprehensive smelter refurbishment programme aimed at significantly boosting output from its recently regained operations.

Bloomberg quoted the company as saying that the facility will undergo a complete shutdown and full-scale modernisation to enhance both structural integrity and operational efficiency.

This strategic move comes nearly a year after Vedanta, controlled by Indian billionaire Anil Agarwal, resumed management of KCM following the resolution of a protracted dispute with the Zambian government.

As part of the settlement, the company committed to investing over $1.2 billion within five years to revitalise operations and address creditor obligations.

Since regaining control, Vedanta has already deployed more than $400 million into KCM, including $250 million for debt settlement and a $ 150 million capital instalment.

While the majority of these funds are earmarked for completing development of the crucial Konkola Deep underground mine, the smelter refurbishment represents a key component of Vedanta's ambitious plan to increase annual production to 300,000 metric tonnes by 2030—a dramatic rise from current levels below 30,000 tons.

The smelter upgrade addresses critical infrastructure challenges that recently compelled Zambia's government to temporarily waive export taxes on 255,000 tonnes of copper concentrates—a measure partly necessitated by KCM's current processing limitations.
