The separation of copper from nickel is based on the fact that there is an appreciable difference in the pH at which the two metals are extracted. Copper can be extracted, with very small amounts of nickel, at pH 6.0 to 6.5, while nickel is extracted from the copper raffinate at pH 8.0 to 8.2.
The North Konawe region in Indonesia, known for its lateritic nickel (Ni) deposits, holds significant potential for obtaining Ni resources. However, the complex topographic conditions of this area pose challenges. Exploring the application of remote sensing technology to reveal the spectral response mechanism of Ni grade from high-precision multispectral data …

Lateritic Nickel Ore Processing. While sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores. A variety of approaches are available to process nickel laterite ores, with the most prevalent approaches explained below.
The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the …
Nickel laterite ore is used to produce nickel metal, predominantly to manufacture stainless steel as well as nickel sulfate, a key ingredient in the batteries that drive electric …
In anticipation of future demands, a comprehensive understanding of the chemical and mineralogical characteristics of nickel-bearing minerals is a prerequisite to devising effective nickel beneficiation methods. Of particular importance are markers in the mineralogy of the flotation concentrate that inform beneficiation strategies to improve concentrate grades, …
The Ni-Co laterite deposits involved in our analysis are mostly well explored and are partially or entirely mined. These deposits contain reliable quantitative data on ore …
In this paper, the process of solid-state metalized reduction and magnetic separation was investigated for preparation of nickel–iron concentrate from a low-grade laterite nickel ore. The effects of reduction temperature, reduction time, amount of dosages, and magnetic field strength on grades and recoveries of nickel and iron were studied. The results …
The shift to lower-grade ore, while driven by practical considerations, raises questions about production costs and overall efficiency. The Philippine ore's lower grade necessitates more substantial quantities to achieve the same nickel content as Indonesian ore. This, in turn, can lead to higher operating costs due to increased processing ...
Metallic ore grades are falling globally as the higher grade reserves are exploited first and are progressively depleted. At the same time, the demand for primary metals extracted from these ores ...
used to simulate various extraction scenarios, such as the effect of changes in ore grade, processing . methods, and environmental factors. Simulation techniques can also optimise mineral processing ... Mineralogical characterization of low-grade nickel laterites from the North Oman Mountains: Using mineral liberation analyses–Scanning ...
Sensor-based automatic ore sorting technologies are used in the minerals industries to efficiently remove waste and sub-marginal grade material from crushed and screened run of mine (ROM) ore, producing a coarse (typically >10 mm) upgraded pre-concentrate at an early stage in the mineral processing circuit.
Two broad ore types. Nickel occurs in two broad ore types: laterite (oxide) ores, principally located in tropical and sub-tropical areas, and; sulfide ores, principally located in the temperate to sub-Arctic regions. Major nickel mining locations are depicted in the map – but some of these locations have many operations, and some only one.
The major challenge faced by these conventional techniques on low grade lateritic ores includes high processing cost, stricter environmental regulations on effluents and requirement of high ...
Using Crawford as an example, Hughes finds that, based on a nickel price of USD$17,000 per tonne, and using the roasting process from Dumont's feasibility study, the higher-grade ore would deliver CAD$34 per tonne and …
The incentive for the present research was to develop a new carbothermic reduction process for nickel laterite ore that would produce a higher grade of nickel than current industrial techniques.
The challenges in processing nickel laterite ores using flotation process were comprehensively reviewed. Literature shows that flotation has not been successful to recover nickel from laterite ores. ... Mineralogy and crystal chemistry of a low grade nickel laterite ore. Trans. Nonferrous Metals Soc.
