A novel method of high-grade ferronickel production was developed using self-reduction and selective oxidation. • Oxidation by CO 2 at a concentration of 70 vol% allowed for a nickel recovery >95% and grade of ~32 wt%.. Metallic nickel and iron were separated by selective oxidation with CO 2, and CO 2 was efficiently utilised.
Low-temperature roasting, selective decomposition and water-leaching were used to extract nickel and copper from low-grade nickel sulfide ore with highly alkaline gangue. The effects of variable factors, such as the dosage of roasting additives, the ore particle size, roasting time and roasting temperature, selective decomposition …
The primary aim of pelletizing the nickel laterite feed prior to reduction lies in maximizing the efficiency of the roasting step by improving bed permeability. Improving the bed permeability, or how well gases are able …
1. Introduction. Stainless steel industry, as the main application field of nickel, occupies high consumption ratios of nickel both in the world and China over recent years, and the ratios have reached up to 68% and 80%, respectively, in 2020, resulted in an ever-increasing demand for nickel [[1], [2], [3]].With the continuous depletion of sulfide …
In 2022, the nickel market moved into a surplus of 114 kt, or 4% of annual consumption (compared to a deficit of 172 kt in 2021). Historically, market surpluses have been linked to the LME deliverable / Class 1 nickel. However, in 2022, the surplus was mainly represented by the low-grade nickel units, particularly nickel pig iron (NPI) and FeNi.
The results showed that when the amount of low-grade ferronickel concentrate added was 30 wt.% and the amount of CaF 2 added was 9 wt.%, high …
An electrochemical approach is able to convert low-grade nickel-copper matte (LNCM) to copper-, nickel-, and iron-alloys in both molten NaCl-KCl and MgCl 2-NaCl-KCl without sulfur dioxide emissions.Since the LNCM contains the mixture of sulfides and oxides, the electrochemical deoxidation and desulfurization are taking place …

Metals Battery Metals. The case for low-grade sulfide nickel deposits. October 4, 2022. 2022.10.04. Nickel deposits come in two forms: sulfide or laterite. About 60% of the world's known nickel resources are laterites, which tend to be in the southern hemisphere. The remaining 40% are sulfide deposits. The main benefit of sulfide ores is …
Shake flask bioleaching of a low-grade nickel-cobalt-copper sulfide ore from Lao was investigated to test the technical feasibility to recovery metals from this ore. The mineralogical results indicated that the valuable minerals were disseminated finely and the ore had a low content of sulfur and high content of iron and magnesium, which was very …
As the world's second-biggest supplier of nickel ore, the country exported 577,000 metric tons of it in 2016 and 2017 combined.Last year's nickel ore exports came in at 230,000 metric tons — a third less than the 2016 figure—but still raked in $455.21 million (P24.533 billion) for the country in 2017, according to the United Nations ...
To improve beneficiation of nickel and iron from low-grade saprolite laterite with 1.29 wt.%Ni and 16.31 wt.%Fe, co-reduction with limonitic laterite ore and basicity optimization were adopted as strengthening measures in this paper with better economic …
Fig. 2 shows the microstructure of nickel laterites and the occurrence regularity of nickel based on the SEM-EDS study. It can be seen that lizardite and goethite are the major mineral constituents and main nickel-bearing minerals containing 1.35% and 0.94% Ni in the two types of nickel laterites, respectively, with characteristics of …
