Abstract:
AbstractThe production of a nickel sulphide concentrate through selective sulphidation of a nickeliferous lateritic ore at temperatures lower than current smelting temperatures, is being studied as a potential production method for upgrading lateritic ores. The ability to produce such a nickel sulphide concentrate at economically attractive grades, while achieving reasonable nickel recoveries, relies on the conversion of the maximum amount of nickel oxide to sulphide, while minimizing the amount of iron sulphide. This paper examines the thermodynamic basis for this selective sulphidation. The

The goal of the work was to determine and characterize the inclusions of nickel sulphide in tempered glass. During the tempering process where the glass is heated the nickel sulphide stones are completed transformed to the high temperature modification which is unstable when the temperature decreased. The glass samples, which include the NiS stones, were investigated by microscopic method (SEM) and characterized by EDAX analysis. The glass samples were analysis by elastooptic studies but it did not prove occurrence of stresses. Obtained results will help to solve the problem with forming nicke

Abstract:
Abstract Reduction mechanism and kinetics of NiS nickel sulphide obtained during the process of nickel sulphidation, have been studied as a function of temperature (723-873 K). It has been found that the reduction process follows linear kinetics with activation energy of 103 kJ/mol. It is important to note that during nickel sulphidation and after the reduction of nickel sulphide, the product sample shows highly developed surface, creating thus the potential possibilities to be applied in heterogeneous catalysis.

The analyses of the results obtained showed that particle size, pH, and flotation time had significant effects on the recovery of nickel sulphide ore. The particle size distribution showed that the breakage rate increased in coarse particles and decreased with reduction in particle size.

AbstractThis paper describes the determination of the individual platinum-group elements by X-ray fluorescence after nickel-sulphide fire-assay collection. The platinum-group sulphide residue obtained after the dissolution of the nickel is dissolved in acid, and reduced to the metal by use of sodium borohydride. The finely divided metals are then filtered onto a millipore filter, and measured by X-ray fluorescence spectroscopy. The procedure makes use of gold as an internal standard. Factors affecting the accuracy and precision are investigated.

AbstractNickeliferous limonitic laterite ores are becoming increasingly attractive as a source of metallic nickel as the costs associated with recovering nickel from the sulphide ores increase. Unlike the sulphide ores, however, the laterite ores are not amenable to concentration by conventional mineral processing techniques such as froth flotation. One potential concentrating method would be the pyrometallurgical solid state reduction of the nickeliferous limonitic ores at relatively low temperatures, followed by beneficiation via magnetic separation.

Copper-nickel low grade ore deposits normally have complex mineralogy and process behaviour. Implementing an optimum process that is able to recover all the valuable minerals efficiently is challenging. One concentration strategy in mineral processing of copper-nickel sulphide ores is stage-wise flotation. The first flotation stage concentrates mainly copper minerals. The copper middling is re-floated to obtain nickel concentrate.During the industrial process of copper-nickel ore, it was observed that significant amount of nickel sulphides was lost to the tailings during the nickel flotation.

Abstract:
Abstract A new nickel-base high-temperature alloy, "alloy 10 Al", which contains 30 % iron, 10 % aluminium and 8 % chromium, has been developed. Alloy 10 Al has a lamellar eutectic two-phase microstructure with one phase being the intermetallic phase NiAl and the second phase being Ni(Fe,Cr) solid solution. The high-temperature corrosion behaviour of the new alloy has been determined in both air and hot process gases containing methane, sulphur dioxide and hydrogen sulphide, respectively. It was found that the corrosion resistance against carburization, sulphidation and oxidation was excellent

Abstract:
Abstract Copper nickel alloys which are able to harden by precipitation reactions involving aluminium are described. The main precipitation species is Ni3Al present as 10 nm - 15 nm size particles, and strengths above 750 N/mm2 proof stress have been achieved. Two such alloys have been commercialised and they demonstrate higher corrosion resistance to marine environments than standard cupronickels, most probably due to the passivating influence of aluminium. The reaction of one of these alloys with sodium chloride both with and without the presence of sulphides has been studied, using weight l

Abstract:
Absrract The high strength and corrosion resistance of nickel-chromium-iron alloys, such as UNS N07718 (Alloy 718), UNS N09945 (Alloy 945) and UNS N09946 (Alloy 945X) make them particularly good candidates for use in demanding environments in the upstream oil and gas industry. These materials generally perform well where resistance to sulphide stress cracking and chloride stress corrosion cracking is required. However, whilst these alloys are considered ‘NACE compliant' environmentally-assisted failures can still occur. It is generally accepted that for hydrogen cracks to initiate, there must
