There are outliers. Shifts in the global climate over geological history have enabled places like arid inland Australia to form laterite deposits. This region was once bathed in tropical rainfall and lush jungle.
But of the two sources of nickel, sulphides are far easier to process and refine into high-purity products, the ideal choice when it comes to EV battery material. For this reason, sulphide miners have retained a competitive edge.
However, that started to shift in 2018 when the world’s largest nickel producer, China’s Tsingshan Holding Group, announced a $700-million plan to produce battery-grade nickel from nickel laterites. Processing laterite ore into high-purity nickel uses a system known as High-Pressure Acid Leaching (HPAL). The innovation unlocked a swathe of new supply and Indonesia’s nickel output exploded after integrating HPAL technology in 2018.
