Production from a large new zinc mine in the Democratic Republic of Congo will be split between several new buyers including trading giant Trafigura Group, after rival Glencore backed away from a previous deal for the entire supply. Ivanhoe Mines’ Kipushi zinc mine started production in the past few days and is finalizing deals to sell its zinc to Trafigura, China’s Citic and Boliden, according to people familiar with the matter, who asked not to be identified as the matter isn’t public.
