US Patent Application for PROCESSING OF LATERITE

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. This implies that along with the nickel in laterites, all the associated gangue must be processed in capital and energy intensive processes like smelting or pressure leaching. Get price
