Abstract

Nickel slag is a product that is formed at high temperatures to form metal alloys that are stable enough. It becomes a challenge for researchers to find methods for extracting valuable metalcontent. Leaching is one of the solid-liquid extraction methodsthat can be applied to separate important elementsfrom a solid material. By using strong acid solvents. Leaching of ferrous metal (Fe) as the main metal innickel slags was carried out with a 98% 2M sulfuric acid extracting solution. Destruction of theleachate of nickel slagwas then conducted tosimplify the complex elements in the samples so that they could be easily analyzed.Destruction of nickel slag leachate samples wascarried out using a destructive solutionin the form of nitricacid. The maximum yield of iron content was obtainedat a size of 140 mesh and 60 minutes with an iron content of 19,141 ppm. The minimum yield of iron content was obtainedat 80 mesh-30 minutes of leaching with an iron content of 18,433 ppm. The maximum recovery results were obtained at 140 mesh-60 minutes of leaching. Factors that can influenceinclude solid sample size, extracting solution, mineral form in solids, complexity, pH, operatingtemperature, and leaching time.
