Abstract:

Nikel laterit adalah mineral logam hasil dari proses pelapukan dan pengkayaan mineral pada batuan ultramafik. Geologi di daerah Palangga, Provinsi Sulawesi Tenggara, disusun oleh batugamping dari Formasi Eimoko dan Formasi Langkolawa yang memiliki hubungan ketidakselarasan dengan batuan ultramafik di bawahnya sebagai pembawa endapan nikel laterit. Proses pelapukan pada batuan ultramafik menghasilkan karakter dan profil nikel laterit yang berbeda. Penelitian ini bertujuan untuk mengidentifikasi karakterisasi nikel laterit berdasarkan pada mineralogi dan profil dari Zona lateritisasi. Berdasarka

Abstract:

The gangue mineral surface inevitably enriches some copper ions, nickel ions and other metal ions when copper-nickel sulfide ore is ground and in the flotation process. These ions can activate the gangue minerals so as to influence the selective separation of valuable minerals and gangue minerals. This paper, based on the ore property, found that complexing agent LXA could make nickel grade increase to 7.88% from 6.32%, but the recovery rate reduced by 15.61%; complexing agent LXH1 could make nickel grade and recovery rate increase by 0.6% and 1.3% respectively by comparing the flotation effec

Abstract:

In this study, segregation roasting and magnetic separation are used to extract nickel from a garnierite laterite ore. The garnierite laterite ore containing 0.72% Ni, 0.029% Co, 8.65% Fe, 29.66% MgO, and 37.86% SiO2 was collected in the Mojiang area of China. Garnierite was the Ni-bearing mineral; the other main minerals were potash feldspar, forsterite, tremolite, halloysite, quartz, and kaolinite in the garnierite laterite ore. The iron phase transformations show that nickel is transformed from (Ni,Mg)O·SiO2·nH2O to a new nickel mineral phase dominated by [Ni]Fe solid solution; and iron cha

Abstract:

Mineralogy research of the copper and nickel ore from Jinchuan is completed in detail that shows the mineral compositions and their percentage and particle size distributions of the valuable minerals. The main valuable minerals are pyrite, violarite, chalcopyrite which are closely associated with other sulphide minerals. These results provide an important basis for the beneficiation tests.

Abstract:

To understand the nickel supergene enrichment mechanism in the lateritic process, we have conducted a preliminary analysis of the micro-morphology and micro-area chemical characteristics of the nickel-carrying minerals of garnierite, sampled from the Kolonodale area of Sulawesi Island in Indonesia. The SEM + EDS analysis shows that, the main nickel-carrying minerals in garnierite are serpentine and talc. The micro-morphology of the talc is fragmented and in piling structure. The micro-morphology of serpentine manifested tubular, fibrous, plate-like and other morphologies, showing the staggered

Abstract:

The useful minerals of Jinchuan high-grade copper and nickel suphfide ores were mainly nickel and copper, whose grade were respectively 1.42% and 1.01%. The content of MgO and SiO2, main gangue components, reached 57.89%. The key to improve the separation indexes of flotation concentrate was to inhibit the gangue minerals effectively, therefore, the effects of different kinds of regulators on Jinchuan high grade copper-nickel ores by flotation were studied. Considering the grade and recovery of concentrate comprehensively, the optimal regulator of mineral flotation was determined to be the com

Abstract:

The resource intensity of primary nickel production in China was analyzed by the indicator of exergy, which can provide a unified picture about the overall processes involved in the life cycle of nickel. The results show that primary nickel’s CExD value is 235GJex/t, and the largest contributor to the CExD is electricity (46%), followed by fuels (31%), mineral (16%), and land resource (7%); the considerable proportion natural mineral and land resource account for in the result is due to the high exergy value of sulphide minerals and the low grade of natural nickel ore. The results also show th

Abstract:

The concept of mineral system, which interprets mineral deposits in relation to terrestrial dynamics, is currently used to interpret the genesis of deposits holistically, being an important tool for mineral research. In this sense, the present work makes an interpretation of nickel laterite according to the precepts of mineral systems and points out potential areas for further research in Brazil. One of the main sources of nickel comes from minerals formed by surface changes of ultramafic rocks submitted to tropical climates and relative tectonic stability, with several potential regions in Br
