Thermal upgrading is the part of selective reduction process which is for nickel extraction with holding temperature in low (300-500℃) before reduction process. The mixing way of laterite makes them useful for extraction and no bounding in the roasting process which has problem in impurities. The optimum carbon percentage is the concerned purpose for this research. The ratio of saprolite and limonite (solid: solid) are 1:4 and gave heat treatment at 250℃ for 60 minutes and continue to 1150℃ with 1 h holding time and magnetic separation for getting the optimum nickel grade and recovery. All samples are analysed with XRD, XRF, and SEM-EDS to get info on the phases, chemical composition, and morphology. The optimum ratio result based on minimum impurities in the product is 1.5% carbon, with the nickel grade is 2.93 wt.%. [ABSTRACT FROM AUTHOR] |
