Naturally found in two forms, laterite and sulphide deposits, the majority of nickel currently mined is nickel sulphide, because it is easier and cheaper to process. [Image changes …

The scheme is based on collective flotation of all sulphides using isobutil xanthate in the experiments. We proceeded from the amount of reagents (xanthate—170 g/ton, aerofloat—120 g/ton, sodium carbonate—2000 g/ton, copper sulphate—50 g/ton) consumed per 1 ton of the copper–nickel ore at a sulphide content of 10%.

The sulphide ore is amenable to producing battery-grade nickel sulphate which is forecast to be in short supply due to the surge in demand for EVs. Valuation looks very reasonable on a market cap ...

Within the channellized ore environment, elevated Ni and low Cr values are observed in the lower flow unit of the ultramafic pile (Fig. 4 a). Nickel concentrations exceed those of Cr, so the Ni : Cr ratio is >1. Higher in the ultramafic pile, Ni decreases as Cr increases. Download : Download full-size image; Fig. 4.

An ore typical of the Merensky reef was acquired from one of the Merensky processing operations. The bulk sample was crushed, blended, riffled and split using a rotary splitter into 1 kg portions.Synthetic plant water (Wiese et al., 2005a, Wiese et al., 2005b) was used for all batch flotation tests.The 1 kg ore samples were milled in …

A new extraction technology of chlorination roasting with a mixture of MgCl 2 ·6H 2 O and NaCl was investigated to co-extract nickel and copper from low-grade nickel ores. The effects of some key factors on the extraction of nickel, copper, and iron were studied, and the results show that,when the roasting temperature is 850°C, the roasting …

Nickel sulphide ore is mined at our open-cut and underground operations in the Northern Goldfields of Western Australia. It is then crushed and concentrated using nickel sulphide flotation technology, before being dried and railed to the Kalgoorlie Nickel Smelter, where it is fed to a flash furnace. This produces a granulated matte product ...

The sulphide minerals in nickel ores are easily floatable without a collector in acid pulp due to oxidation and, therefore, their separation is not possible at low pH. ...

Naturally found in two forms, laterite and sulphide deposits, the majority of nickel currently mined is nickel sulphide, because it is easier and cheaper to process. [Image changes to a pile of manufactured nickel rods and then to a rock of nickel sulphide ore] However, the majority of the world's reserves, around 70%, are laterites.

The focus of this study is to characterize the bacterial community structure present during stirred-tank bioleaching of a low-grade nickel sulphide ore at different temperatures (5 to 45 °C) and pH levels (3 and 5).This is a continuation of previous work, which was designed to assess the technical feasibility of applying elevated-pH …

Nickel* CATHERINE KLEIN, MAX COSTA, in Handbook on the Toxicology of Metals (Third Edition), 2007. 3.1 Production. Nickel exists as a natural earth element, primarily in sulfide or oxide ores that are mined underground or in open pits. It is the 24th most abundant element on earth, with the greatest deposits of nickel ores in Canada, Siberia, and New …

Indonesia's high-grade 1.7% nickel ore is mainly used for the country's nickel pig iron (NPI) production, a feedstock for stainless steel, while lower grade is used to make products for the ...

The rougher flotation and closed-circuit flotation tests of copper-nickel sulfide ore (1.0 kg) were performed on XFD-63 type flotation machines of different capacities (3.0 L, 1.0 L, obtained from Wuhan Exploration Machinery Co., Ltd.) [5], with mechanically stirring speed of 1610 rpm.The 3.0 L cell was used for rougher and scavenger stages, …

The rate of solution filtration through a layer of ore was determined in percolators with a volume of 3 liters with an ore weight of 3 kg and layer thickness ≈600 mm. Ore size was determined by leaching for 35 days in troughs with S:L = 1:3 by sulfuric acid solution with a concentration of 10 g/liter and bioreagent of 10 g/liter with respect to …

In this work, a two-stage sulphuric acid roasting and water leaching system was chosen to extract valuable metals from Chinese low-grade nickel sulphide ore. By optimizing the two-stage roasting process, first roasting temperature at 295°C with particle size of 80–91 μm with an acid-ore ratio of 1.1:1 for 2 h, and second roasting temperature at 620°C for 2 h, it …

It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C. Iwasaki et al., (1961) and …

The sulphidation of a nickeliferous lateritic ore was studied at temperatures between 450 and 1100 °C and for sulphur additions of 25–1000 kg of sulphur per tonne of ore. The experiments demonstrated that the nickel could be selectively sulphidized to form a nickel–iron sulphide. It was found that both the grade and the sulphidation degree ...

Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) …
