Jun 20, 2019· Nickel laterites are unusual in the base metals industry, in that the ore cannot be readily beneficiated prior to processing (Reference 1). In contrast, nickel sulphide ores are typically of similar nickel grade to laterites, but can be beneficiated by flotation, to produce a much higher-grade concentrate which is then smelted.
