Potensi dan Karakterisasi Limbah Metalurgi “Slag Nikel Pig Iron”
In recent years, the growth of mineral processing industry is growing rapidly, including producing non-ferrous materials such as nickel, aluminum, and copper. This has an indirect impact on the increase in metallurgical waste resulting from the processing of these materials. In Indonesia, metal processing slag , including Nickel Pig Iron (NPI) slag , is a waste that has yet to be used optimally. On the other hand, NPI slag contains elements such as Pb, Zn, As, Cd, and Co, which have the potential to pollute the environment and harm humans. Therefore, it is necessary to utilize NPI slag as a more valuable product to increase the economic value of metallurgical waste and minimize environmental pollution. In this paper, studied characterization of NPI slag has the potential to be developed as a geopolymer. The characterization was carried out by EDS mapping and XRD on slag NPI with a size of 200 mesh. The characterization results show that there are phases of quartz, clinoenstatite, sillimanite, calcium peroxide, olivine, forsterite, fayalite, and hypothetical silica. The phase was identified through the peaks of the XRD diffractogram at an angle of 20-70. In addition, the mapping results indicate that several compounds, such as silica, magnesium, and oxygen, are
