“…Calcination phase is used to removal of bond water. Keskinkilic et al [42] investigated calcination characteristics of laterite ores (Ni 1.26%, Fe 32.6%). The complete calcination process contained two aspects, the removal of chemically bound water during the goethite-haematite transformation and the elimination of volatiles in the 350-700℃ interval.…”

Abstract. Nickel laterite ores are important nickel resources, which are abundant and account for approximately 70% of the world nickel reserves. However, nickel in nickel laterite ores could not be extracted by conventional separation methods. Consequently, treating and utilizing nickel laterite ores efficiently is of vital importance. This article reviews hydrometallurgical processes, pyro metallurgical methods, and reduction roasting-magnetic separation technique with reference to current studies of treating processes for nickel laterite ores.

“…Roasting is one method utilized in metal recovery, particularly in sulfide exposure. The metal is heated to 350-750 o C in air or oxygen during the roasting process to form metal oxides and eliminate sulfur dioxide or other sulfur compounds, sulfur removal, metal verification of sulfide compounds, and getting ready for the subsequent recovery stage are some of the uses for this method [22]. During the roasting process, additives are added to obtain a higher extraction percentage.…”

The creation of nickel-smelting products including important metals like nickel, cobalt, and copper is a persistent issue in the nickel mining business. Another secondary source of precious metals is nickel slag. In addition, the massive amounts of nickel slag generated by the nickel smelter sector will pollute the environment, particularly the soil, since the smelting slag contains hazardous materials. This study examines techniques for recovering precious metals from nickel slag by reviewing publications from Springer Link, Google Scholar, MDPI, ScienceDirect, Membrane Journal, and other authors. The two types of metal recovery techniques from nickel slag that were examined were hydrometallurgical and pyrometallurgical techniques. This review article describes a pyrometallurgical method that involves roasting and selective reduction. In the meantime, the hydrometallurgical techniques were examined in the high-pressure oxidative acid leaching process, the atmospheric acid leaching method, and the bioleaching process. A roadmap for research designs that can be used to recover valuable metals from nickel slag sustainably has been created due to the completed literature evaluation.
