KARAKTERISTIK SIFAT FISIS BATUAN NIKEL DI SOROWAKO SULAWESI SELATAN

E. H. Sujiono, M. Diantoro, Samnur -

Abstract


Sulawesi Selatan memiliki cadangan nikel berlimpah di daerah Sorowako, Kabupaten Luwu Timur, yang sampai saat ini masih terikat kontrak karya dengan P.T. Vale Indonesia. Potensi nikel dalam jumlah besar dan terus bertambah sehingga dalam proses produksi dan eksplorasinya harus tepat, ramah lingkungan agar memiliki nilai ekonomi tinggi. Data yang dilaporkan dalam penelitian ini berupa hasil karakterisasi komposisi unsur, senyawa dan kekerasan batuan nikel. Pemilahan dan penyiapan sampel dilakukan secara manual dalam ukuran 2 cm x 2 cm x 0,5 cm. Hasil analisis menunjukkan bahwa komposisi utama dari batuan nikel didominasi oleh nikel (Ni) dan silikon (Si). Kekerasan batuan nikel mencapai 130 sampai 155 HVN-100 serta temperatur transisi gelas pada kisaran 9000C. Berdasarkan data ini, batuan nikel potensial untuk diolah secara industri.

ABSTRACT

South Sulawesi has abundant reserve of nickel in Sorowako, East Luwu, which is still in the status of work contract bond with P.T. Vale, Indonesia. The huge nickel potential of the area and the growing production brings the need to process the exploration precisely and friendly to generate high economic value. The data reported in this study are characterization result of the elements composition, compounds and hardness of the nickel ore. Samples were prepared manually, each in size of 2cm x 2cm x 0,5cm. The analysis showed that the main composition of the nickel ore was dominated by nickel (Ni) and silicon (Si). Nickel ore hardness reaches 130 to 155 HVN-100 as well as the glass transition temperature in the range of 9000C. Based on the data found, the nickel ores are furthermore processable industrially.
