Environmental context Remediation technologies often rely on manipulation of redox conditions or natural redox processes to favour microbial sulfate-reduction and mineral sulfide formation for treatment of inorganic contaminants in groundwater, including nickel. However, few data are available on the structural properties, solubility and mineral transformation processes involving nickel sulfides. These data are needed in order to constrain the long term performance of groundwater remediation efforts.

The crystallization rate of copper and nickel sulfides influences on the phase formation processes. The high crystallization rate (about 103 degrees/s), achieved through granulation of the sulfide copper-nickel melt, leads to the stabilization of non-stoichiometric phases, the formation of ultrafine structures, which are grains and partial dissolution of the metal component in the sulfide. The structure of the granules is formed by nickel sulfide (Cu1.96S) phases in the form of dendritic inclusions of 2-20 µm in size in the nickel sulfide phase (Ni3S2).

A low-temperature precursor sulfuration route has been established to prepare metal sulfides with different nanostructures during the synthesis of nickel sulfide. The advantages of the low-temperature precursor sulfuration route were testified by the synthesis of different metal sulfides ( lead sulfide, zinc sulfide and cobalt sulfide). It offers a novel path to the preparation of other metal sulfides.

The increasing demand for electric vehicles affects the high demand for nickel-based batteries, including Nickel Manganese Cobalt (NMC) batteries. Generally, NMC is processed from high-quality ore (sulfide ore) to produce nickel (II) sulfate hexahydrate or NiSO4.6H2O. But sulfide ore face scarcity due to a long history of mining and exploitation. Thus, laterite-type nickel ore can be an alternative to nickel resources. This study aims to produce mixed sulfate precipitates from a ferronickel leaching solution that can be utilized further to produce NiSO4.6H2O. Also, this research will study the

Dense medium separation (DMS) is a method often used to upgrade base metal sulfide (BMS) ores before their main processing stage, with varying results achieved for different ore types. The process makes use of the density differences between the BMS minerals and the lower density silicate/carbonate gangue minerals, using a separating medium of density between the two ore components. The separation is accelerated using a dense medium cyclone (DMC) to form two products: overflow (tailings) and underflow (concentrate). The purpose of DMS is to reject large quantities of gangue upfront, resulting

Abstract Sections of CDA 706 piping and Monel 400 tubing were severely pitted after exposure to marine and estuarine waters. Pits developed under surface deposits of mixed bacterial communities containing 104-105 sulfate-reducing bacteria (SRB). Localized corrosion was attributed to a combination of differential aeration cells, a large cathode::small anode surface area, concentration of chlorides, development of acidity within the pits and the specific reactions of the base metals with sulfides produced by the SRB. Chlorine and sulfur reacted selectively with the iron and nickel in the alloys.

Abstract The corrosion tendency of copper-nickel alloys in sulfide polluted seawater was investigated under simulated jet impingement conditions. It was found that under high jet impingement velocity the corrosion of these copper-nickel alloys decreases with increasing sulfide concentration. A new mechanism is proposed to explain this unexpected behavior. This behavior was attributed to the sweeping away of corrosive agents with increasing jet velocity. In addition it was found that complexing agents such as Erichrome Black-T (EBT) can render sulfide to be more aggressive and enhance the corro

Abstract Corrosion in 90/10 Cu-Ni pipes was evaluated using estuarine water from the Gulf of Mexico at the mouth of the Pascagoula River, maintained at a flow rate of 3 to 6 ft/sec over a 1-year period. The impact of surface preparation, batch FeSO4 (50 ppb Fe+2 for 48 hours) pretreatment, and intermittent treatment was evaluated. Surface deposits were characterized by scanning electron microscopy and energy-dispersive x-ray fluorescence spectrometry. Water analyses included pH, dissolved oxygen, dissolved sulfide and sulfate, total organic carbon, total suspended solids and dissolved heavy me

This project will test trace element signatures within indicator minerals in well-defined, Western Australia-based case studies and determine their robustness throughout the weathered and transported cover. We will focus on rapid, practical analysis to apply this tool in a new, efficient workflow for exploration of magmatic Nickel-Copper-Sulfide deposits.

Polymetallic (Ni-Mo-Zn-Pt-Pd-Au-Re) hyper-enriched black shales in the northern Canadian Cordillera consist of thin, semi-massive sulfides interbedded with black shale. We studied HEBS deposits at Nick, Peel River, Monster River, and Moss in northern Yukon, and at a single locality underlying the Cardiac Creek Pb-Zn-Ag deposit in northeastern British Columbia. High-grade mineralization contains up to 7.4 weight per cent Ni, 2.7 weight per cent Zn, 0.38 weight per cent Mo, 400 ppb Pt, 250 ppb Pd, 160 ppb Au, and 58.5 ppm Re. Sulfide mineralization formed during syngenesis to later diagenesis. A

As we move away from a fossil fuel-driven economy, the demand for metals used in energy-dense, rechargeable batteries is increasing; these include cobalt and lithium. Although cobalt is mostly obtained as a by-product from nickel and copper mining, significant amounts also occur in volcanogenic massive sulfide (VMS) deposits, of which Canada has many. However, the primary controls on cobalt distribution in VMS deposits are poorly understood, and may be affected by deformation and metamorphism. We show that cobalt can occur in pyrite, which retains its primary composition through greenschist fa
