Zambia’s Minister of Mines Richard Musukwa said on Wednesday nine companies would submit bids for Konkola Copper Mines, which is at the centre of an ownership dispute with Mumbai-listed Vedanta, within weeks. "The bidding process will start once all the companies have conducted due diligence and we are hoping this can happen within a couple of weeks," Musukwa said at a media briefing, adding companies from Russia, Turkey, Australia, Canada and China were doing due diligence.
