Successful leach testing of high-grade nickel concentrates from Vancouver-based explorer FPX Nickel’s Decar nickel district, near Fort St James, British Columbia, has confirmed nickel recoveries up to 99.5% in producing a high-concentration nickel/cobalt chemical solution suitable for the electric vehicle (EV) battery supply chain. The results of this test programme position Decar as a potentially significant supplier of nickel for the stainless steel and the EV battery markets, the company indicated in a statement on Tuesday.
