Abstract

Salah satu daerah yang terjadi perubahan kualitas tanah akibat aktivitas pertambangan adalah Kabupaten Luwu Timur tepatnya di Desa Ussu Kecamatan Malili. Lahan yang dulunya hutan sekarang menjadi lahan terdegradasi, sehingga perlu dilakukan penelitian terkait kualitas tanah lahan bekas tambang. Tujuan dari penelitian ini adalah untuk mengetahui pH tanah dan kandungan mineral pada lahan bekas tambang nikel dan mengetahui kualitas tanah menggunakan parameter pH tanah dan kandungan mineral pada lahan bekas tambang nikel. Terdapat 6 titik pengambilan sampel dengan metode pengambilan sampel yaitu grab sampling. Sampel yan gtelah diambil kemudian dilakukan analisis pH dan analisis X-Ray Diffraction. Hasil analisis didapatkan pH tanah dengan nilai 6,2 sampai dengan 6,8 (agak asam) sehingga dapat dikatakan bahwa pH tanah tersebut kurang baik untuk tanaman. Hasil pengujian XRD didapatkan kandungan mineral geotit, hematit, kuarsa, gahnit, lizardit dan diopsid. Tanah pada daerah penelitian memiliki pH 6,2 sampai dengan 6,8 (agak asam), dan memiliki kandungan Fe >325 ppm. Nilai pH tanah dan kandungan Fe pada lokasi penelitian menunjukkan angka yang tidak sesuai dengan standar kualitas tanah yang ada sehingga dapat disimpulkan bahwa kualitas tanah pada lokasi penelitian tidak baik. Kualitas tanah yang tidak baik menyebabkan tanaman tidak subur dan sangat sulit untuk tumbuh.

Abstract

One of the obstacles in nickel mining is the change in nickel (Ni) and iron (Fe) content from drilling data that does not match the content at the mining location. The study aims to determine the percentage change in nickel (Ni) and iron (Fe) content from drilling data with the mining location. The research method includes processing samples from drilling results and results at the mining location in the laboratory to determine the comparison of content. The next stage is processing and analyzing content data to determine the average nickel and iron content. The results of the identification of drill point data produced an average content of Ni = 1.90% and Fe = 22.86%. While the average content at the mining location is Ni = 1.86% and Fe = 20.55%. Furthermore, the difference in content at the drilling location and at the mining location can be seen, namely Ni = 0.04% and Fe = 2.31%. From the research results, it can be concluded that the levels of identification results at the drilling location have different levels compared to those at the mining location, where the percentage comparison of nickel levels is 0.04% while iron is 2.31%.

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

Limestone mining for cement plants uses a blasting method to break the material. Blasting production is considered successful when it can achieve production targets based on tonnage of uncovered rock, efficient use of explosives, grain size or rock fragmentation, and environmental impact. This research aims to analyze the blasting geometry on the production results at the research location by knowing the initial design, the actual blasting geometry, and the geometry recommendation using the C.J. Konya method. In addition, researchers also know the explosives used, the production results in the form of material fractionation using the Kuz-Ram method and the tonnage of uncovered rocks. The initial design with a burden of 3.4 m, spacing of 3.4 m, hole depth of 5.9 m, and ANFO explosives per hole of 33 kg produced 147.31 tonnages. The actual geometry with a burden of 1.7 m, spacing of 3.5 m, hole depth of 6.0 m and ANFO explosives per hole of 26.73 kg produced a 77.11 tonnage. The actual geometry resulted in a blasting production of 6,941 tonnes per day, which did not meet the company's production target 10,639. The fragmentation calculation results obtained an average size in the field of 15.29 cm, which meets the required screening or sieve criteria of 0.80 - 1.00 m. The size of the fragments also follows the sieve calculation using the Kuz-Ram method, with a 100 cm sieve passing only 0.01%. Based on this, the company is recommended to make geometry changes to achieve the production tonnage target that has been set.
