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

It is known that to extract nickel from nickel-bearing laterite ore is not an easy job. By reducing roast-magnetic separation, an effective result is achieved in this research in dealing with nickel-bearing laterite ore due to its simple technology process and the high nickel recovery. Nickel-bearing laterite studied in this research is mainly characterized by fine disseminated grain size and easy argillation. Thus, valuable mineral (i.e. nickel oxide) can not be effectively separated from the nickel-bearing laterite ore simply by regular mineral processing technology. To solve the problem, bo

Abstract:

Difficult access to the field in Central Sulawesi causes the process of identifying prospects for mining minerals requires a relatively large time and cost. Therefore, the remote sensing approach can be carried out as a preliminary study to determine the distribution of hydrothermal alterations that characterize the presence of mine minerals. This study utilizes Landsat 8 imagery to obtain the distribution of alteration minerals, especially the group of ferrous mineral oxide and hydroxide minerals, clay and carbonate minerals and Ferromagnesian minerals. The method used is composite (RGB) 4/2,

Abstract:

A new mineral processing and metallurgy technology was proposed, which was that the ferro-nickel concentrate was prepared from laterite ore by coal-based direct reduction. Under the reduction of cheap reductant and the catalysis of composite additives, the effects of coal-based direct reduction were enhanced and the ferro-nickel was extracted. The optimal conditions were followed that the alkalinity was 0.87, and the roasting temperature was 1150°C, and the roasting time is 2.5 hours. The recovery rate of nickel was 86.7% and the nickel content of ferro-nickel concentrate was 5.3%.

Abstract:

Ultramafic nickel ores are difficult to process because they contain serpentine, an anisotropic mineral with a nonspherical morphology and multiple pH-dependent surface charges. Dehydroxylation of serpentine in ultramafic nickel ores by microwave treatment is proposed to improve the processability of these ores. Upon heating, serpentine is converted to olivine, an isotropic mineral that is benign in mineral processing circuits. The microwave heating of two ultramafic nickel ores is explored in this paper, as well as effects on mineralogy and grindability. The first ore was sourced from the Oka

Abstract:

Low grade sulfide ores are difficult to process due to their composite mineralogy and their fine grained dissemination with gangue minerals. Therefore, fine grinding of such ores becomes essential to liberate valuable minerals. In this research, selective flotation was carried out using two pitched blade turbine impellers with diameters of 6 cm and 7 cm to float copper and nickel. The main focus of this research was to generate optimum hydrodynamic conditions that can effectively separate nickel and copper from gangue minerals. In addition, we investigated the effects of superficial gas veloci

Firstly, the co-processing of nickel laterites and sulphidic materials has the potential to offer several advantages that include the use of lower grade (including non-smeltable) concentrates, improvement in the rheological behaviour of the blends, and reduction in the use

Most of direct processes were found to have an overall cost far larger than the CO2 removal tax, because of incomplete carbonation and insufficient properties of the reaction products.

The traditional processes used for manufacturing nickel need high energy consumption and yield a large amount of metallurgy waste residue. A new method was developed. Nickel and iron was enriched firstly by leaching laterite nickel ore in concentrated alkali solution. In the process, silicon entered to the solution in the form of sodium silicate, and nickel and iron were remained in the residue in form of simple oxides due to the destroying of silicate structure.
