Abstract
Berdasarkan data dari Kementrian ESDM, jumlah batubara di Indonesia saat ini sangat berlimpah. Terlebih batubara jenis kelas menengah yang tersebar di Sumatera dan Kalimantan. Akan tetapi sangat sedikit industri, khususnya industri nikel di Indonesia yang menggunakan batubara kelas menengah tersebut. Oleh karena itu dilakukan penelitian pada proses pembuatan nikel dengan reduktor batubara. Penelitian dilakukan dengan melakukan proses aglomerasi briket bijih nikel laterit yang telah dicampur dengan batu bara, fluks, dan natrium sulfat. Proses aglomerasi dilaukan dengan 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 batubara B dengan peningkatan sebesar 1.8%. Dari segi permeabilitas yang paling tinggi pada penggunaan Batubara A.

Data from
Energy and Mineral Resources
Ministry
reveal that there were plentiful amount of coal in Indonesia these
days. Moreover, the middle class coal which straggled all over
Sumatera and Kalimantan. However, measly industrial sector,
especially by nickel industry in Indonesia that were har
nessing the
middle class coals. Therefore, this nickel metal making with coal
based reduction research conducted.
The research conducted by
lateritic nickel ore
agglomeration being briquetted
and mixed with
coal, flux with
sodium sulpha
te. The agglomeratio
n process
carried out with temperature at
1200
o
C
afterward
held for 3 hours.
After
the
agglomeration process,
the outcome of agglomerated
briquetted was characterized with
SEM
-
EDX and XRD test to
understand
the
percentage
of Fe and Ni, phase
s which
formed, and
briquette morphology.
The output of this research
compared with
the initial conditions.
Researchers
obtained the highest increase in
Ni content
using
coal B with an increase of 1.8%. In terms of the
highest permeability on the use of Coal A.
