Abstract

Indonesia memiliki potensial sumber daya alam bahan baku pembuatan silika murni yaitu pasir kuarsa yang telah banyak dimanfaatkan dalam dunia industri. Di daerah Sidenreng Rappang terdapat pasir silika persentase kadar mineral diperoleh SiO2 sebesar 69,14%, sehingga perlu ditingkatkan kadarnya agar bisa maksimal pemanfaatannya. Penelitian dilakukan untuk mengetahui pengaruh kemiringan deck shaking table terhadap kadar dan recovery. Variasi kemiringan deck yaitu 30, 50,80, dan 100. Tahapan pengambilan data penelitian dibagi menjadi empat tahapan yaitu tahap preparasi sampel pasir silika asal Sidenreng Rappang, tahap konsentrasi dengan shaking table, tahap analisis sampel dengan X-Ray Diffraction (XRD) dan X-Ray Fluorescence (XRF) dan tahap perhitungan kadar dan recovery. Analisis sampel awal menggunakan XRD diperoleh kandungan mineral yang didominasi oleh mineral kuarsa, disusul oleh mineral microline dan kalsit sedangkan XRF diperoleh persentase SiO2 sebesar 88,94%, KAlSi3O8 sebesar 8,45% dan CaCO3 sebesar 2,61%. Setelah melakukan percobaan pemisahan SiO2 menggunakan shaking table dengan variasi kemiringan deck, maka dapat disimpulkan bahwa besarnya kemiringan deck tidak mempengaruhi besarnya recovery yang dihasilkan. Recovery optimum pemisahan SiO2 berada pada kemiringan deck 30 dengan nilai recovery 60,21% dan kadar 92,24%.

Abstract

PT Ariano Bintang Cemerlang, Kolaka, Southeast Sulawesi, is one of the companies that manages laterite nickel ore into ferronickel (FeNi) products, with a Cut Off Grade (COG) of 1.40% Ni. In the nickel management process, one of the important steps taken is blending. However, in practice, differences are often found between the projected nickel quality of the barging stockpile and the actual results after the blending process. This study aims to analyze the correspondence between the nickel quality at the barging stockpile and the actual results after blending, identify the factors that affect the difference, and provide recommendations for optimizing the blending process. This study uses a quantitative approach to analyze the conformity between the nickel quality at the barging stockpile and the actual results after the blending process. The results of the blending process analysis show that actual blending has a tendency to produce higher elemental levels in some parameters compared to plan blending. The difference between plan blending and actual blending data can be caused by the material in the stockpile, the inaccuracy of material retrieval, the efficiency of the blending equipment and process, the moisture content and condition of the material, the method of analysis and sampling. A more structured management of materials in the stockpile is needed to minimize these differences.

Abstract

Manganese ores are considered economical and worth selling if they have a purity value above 40%. However, not all mined manganese metal minerals have the appropriate purity value. Manganese metal minerals can be processed using various hydrometallurgical methods to separate metal minerals from their associated minerals using solvents. The purpose of this study is to determine the results of manganese leaching recovery at each variation of temperature and percent solids and to determine the effect of both on manganese recovery. The findings of this study could significantly contribute to the field of metallurgy and mineral processing by providing a deeper understanding of the factors influencing manganese recovery. The method used in this study began with sample preparation. The results of sample preparation were analyzed using XRD (X-ray diffraction) and XRF (X-ray fluorescence). Some of the sample preparation results were leached with several variations in temperature; the leaching results were continued with analysis using AAS (Atomic Absorption Spectrophotometer). The results showed that increasing the leaching temperature and percent solids would increase the leaching reaction rate, resulting in higher Mn recovery.

Abstract

Pasir besi pada umumnya merupakan pasir besi pantai yang banyak tersebar di Indonesia khususnya di Sulawesi selatan. Pasir besi yang mengandung persentase kadar besi yang memenuhi syarat dapat langsung digunakan sebagai bahan campuran, namun berbeda halnya pasir besi yang mengandung kadar besi yang kurang. Daerah sepanjang Pantai Karsut Daerah Jeneponto terdapat pasir besi dengan persentase kandungan Fe di bawah 45%. Kandungan besi yang rendah pada pasir besi dapat ditingkatkan kadarnya dengan pemisahan antara mineral magnetik dengan mineral non magnetiknya. Penelitian bertujuan untuk mengetahui peningkatan kadar dan recovery besi pada bijih besi asal Pantai Karsut Daerah Jeneponto Provinsi Sulawesi Selatan. Sampel awal dianalisis menggunakan X-Ray Diffraction (XRD) dan X-Ray Fluorescence (XRF). Percobaan konsentrasi pasir besi menggunakan magnetic separator dengan variasi kecepatan putar drum yaitu pada kecepatan 200 rpm, 250 rpm, 300 rpm. Produk berupa konsentrat dilakukan analisis XRF dan dilakukan perhitungan kadar dan recovery. Hasil penelitian terhadap sampel pasir besi asal Pantai Karsut Daerah Jeneponto menggunakan magnetic separator diperoleh peningkatan kadar mineral besi oksida Fe2O3 rata-rata sebesar 8,05% untuk masing-masing variasi kecepatan putar drum. Kadar Fe2O3 meningkat seiring meningkatnya nilai kecepatan putar drum, begitupun recovery yang diperoleh. Dihasilkan kadar Fe2O3 tertinggi pada kecepatan 300 rpm dengan recovery 80,88%.

Abstract

Coal remains a major energy source globally, particularly for power generation and industries like iron, steel, chemicals, and cement. Indonesia's coal reserves are widespread, spanning regions such as Aceh, South Sumatra, East Kalimantan, and South Kalimantan. The Mallawa Formation in South Sulawesi also has coal, but it is of low quality due to high ash content, which lowers the calorific value and increases environmental pollution. Therefore, beneficiation is necessary to reduce ash content. The Dense Medium Separation method effectively separates coal from impurity minerals based on density. This study aims to evaluate ash reduction and separation yield across various coal fraction sizes. The coal washing process was conducted on fractions -60+80, -80+100, -100+150, and -150+200 mesh, using a perchloroethylene solution with a density of 1.6 g/ml as the separation medium. Initial coal sample analyses included proximate, calorific value, total sulfur, and mineral matter. Results showed Mallawa coal has 2.94% moisture, 40.60% volatile matter, 47.39% fixed carbon, 9.07% ash, 2.41% total sulfur, and 7053 kcal/kg calorific value, containing quartz, pyrite, calcite, and chlorite minerals. The DMS process on the -150+200 mesh fraction gave the best outcomes, with 50.39% ash elimination and 30.7% yield, making it the optimum size for ash separation in Mallawa coal.
