MEI Blog: Challenges in processing nickel laterite ores by

Jun 06, 2016It's a shame that the highly depressed nickel market led to the cancellation of MEI's October Nickel and Cobalt Processing conference, as there are enormous challenges in the processing of nickel ores, particularly the laterites. The majority of the world's nickel resources occur as laterite ores, which are complex, low grade, and expensive to treat using conventional smelting and high
