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.ABSTRACTSouth 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.

Abstract

This research aims to prepare powder of nickel slag from furnace machine, identify, and analyze of the elements or compounds containing in the sample. The data retrieval was done with the analysis of elemental composition, phase microstructures, crystal size, distribution, and composition mapping of the samples by using XRD, Rigaku Miniflex II, and SEM-EDS, Tescan Vega-3. XRD result indicates that the formation which the similar to amorphous phase was identified and the formation at peak 2θ = 28.01° is identified as the low quartz (SiO2). FWHM 0.18° was obtained using microcal origin 6.0 and average crystal size 53.37 nm was obtained by applying Scherer equation. SEM results show average grain size of samples which is less than 1μm and maximum to 4μm. Based on EDS result, the main constituent elements are Si 32.86 wt%, Mg 19.40 wt%, and Fe 32.03 wt%, respectively.Penelitian ini bertujuan untuk menyiapkan bubuk slag nikel yang berasal dari furnace, yang dilanjutkan dengan mengidentifikasi dan menganalisis unsur atau paduan yang terkandung di dalamnya. Data diperoleh dengan melakukan analisis terhadap komposisi unsur, fasa mikrostruktur, ukuran Kristal, distribusi dan komposisi paduan dari sampel bubuk slag nikel furnace dengan menggunakan XRD tipe Rigaku Miniflex II dan SEM-EDS tipe Tescan Vega-3. Hasil analisis XRD menunjukkan bahwa formasi yang dihasilkan menyerupai fase amorf dan formasi yang terbentuk pada puncak 2θ = 28.01° diidentifikasi sebagai low quartz (SiO2). Dengan menggunakan microcal origin 6.0 diperoleh FWHM 0.18 ° dan menggunakan persamaan Scherer diperoleh rata-rata ukuran kristal 53.37 nm. Hasil pengukuan SEM menunjukkan bahwa rata-rata ukuran butir dari sampel bubuk slag nikel furnace bervariasi antara minimal 1μm dan maksimum 4 μm. Berdasarkan pengukuran EDS diperoleh secara berturut-turut bahwa unsur utama penyusun paduan slag nikel furnace adalah Si 32.86 wt%, Mg 19.40 wt%, dan Fe 32.03 wt%.
