Norilsk Nickel said on Friday that Russian Platinum had withdrawn from talks about creating a joint venture for their Arctic palladium project due to a lack of approval from Rusal, one of Nornickel’s shareholders. Nornickel is the world’s largest producer of palladium, which has been hit hard by the economic fallout from coronavirus. Prices have plunged 45% since February as investors started dumping the precious metal for cash.
