The Democratic republic of Congo has blocked exports of unrefined copper and cobalt concentrates in an effort to push miners to add value to the commodities, before shipping them outside the country, Mines Minster Martin Kabwelulu told Bloomberg.
The order signed by Kabwelulu on April 5, gives mining firms 90 days to clear their stocks before the ban comes into force. “Little by little, within the next three months, we need to no longer export concentrates,” Kablwelulu told Reuters.
