Mineralogical characterization and design of a treatment

Feb 10, 2017· However, it is not suitable for processing low nickel laterite ore from an economic perspective (Nayak, 1985). Moreover, according to the Oheyama process, nickel laterite ore was smelted at a high temperature (~ 1400 °C) in a semi-fused state within a rotary kiln. This was deemed to be the most economic method to treat high-magnesium laterite ore.
