Nickel laterite ores are metallurgically complex and not readily amenable to concentration, pyrometallurgical smelting and refining to metal. As such, alternative technology is required, like intensive
Learn More1. Introduction – Global nickel laterite production The world's resources of nickel are either sulphides or laterites and while almost ¾ of the world's resources of nickel are found as laterites, until 2022 less than half of the primary nickel production came from laterite sources as illustrated in Fig. (Dalvi et al., 2022).
