The potential resources and reserves of nickel ore in Indonesia is the third largest in the world. The potential quite large, but the nickel content found in nature is very small. To increase the added value of nickel ore, it is necessary to process/refine nickel ore. In addition, coal ratio parameter and process temperature in the reduction process, additive is also used as parameter for the composite reduction process. This research used 6 combination saprolite ore composite based on result of previous research. The objective of this research is to know the performance of additive in separation of metal from nickel ore based on result of XRD analysis. XRD analysis is used to know chemical compound saprolite ore composite after reduction process. This results from XRD analysis shown that additive CaCO3 has the best performance additive with higher Fe and Tetrataenite content with percentage of coal ratio of 30% in temperature of 1300 °C. For additive Ca 2 SO 4 percentage coal ratio 15% have higher Fe and NiFeO content in temperature of 1200 °C and 1300 °C.
