Abstract
Saat ini penggunaan Mini Blast Furnace untuk pengolahan bijih nikel laterit di Indonesia masih belum optimal. Oleh karena itu dilakukan penelitian untuk optimalisasi proses salah satunya dengan optimalisasi pada penggunaan fluks. Fluks yang digunakan yaitu dolomit, kerang hijau, dan gypsum. Penelitian dilakukan dengan melakukan proses aglomerasi briket bijih nikel laterit yang telah dicampur dengan batu bara, fluks, dan natrium sulfat. Proses aglomerasi dilaukan dengan heat rate 10 oC / menit hingga temperatur 1200 oC yang kemudian di holding selama 3 jam. Setelah dilakukan proses aglomerasi, briket hasil aglomerasi dilakukan pengujian SEM-EDX dan XRD untuk mengetahui kadar unsur Fe dan Ni, fasa yang terbentuk, dan morfologi briket. Hasil penelitian ini dibandingkan dengan kondisi awalnya. Hasil penelitian ini diperoleh peningkatan kadar Ni yang paling tinggi pada penggunaan fluks kerang hijau dengan peningkatan sebesar 0,6 %. Dari segi permeabilitas yang paling tinggi pada penggunaan fluks kerang hijau.

Today the use of Mini Blast Furnace to the processing of
laterite nickel ore in Indonesia is still not optimal. Therefore
research to optimize the process of one of them by optimizing the
use of flux. Flux used is dolomite, green oyster shells, and
gypsum. The study was conducted by the agglomeration process
laterite ore briquettes which have been mixed with coal, flux, and
sodium sulfate. The agglomeration process have done on a heat
rate of 10 ° C / min up to a temperature of 1200 ° C and then
holding for 3 hours. After the agglomeration process, briquettes
agglomeration results got test of SEM-EDX and XRD to
determine levels of Fe and Ni elements, phases are formed, and
the morphology of the briquettes. The results of this study
compared with the initial condition. The results of this study
obtained an highest increase in Ni content in the use of flux green
oyster shells with an increase of 0.6%. In terms of the highest
permeability in the use of flux green oyster shells.
