Ravensthorpe was a laterite nickel project which, because of the ores' low grade, and expensive and intensive processing requirements, has caused BHP some headaches. The project was originally approved in March 2004 with a budget of $1,340m. But by November 2006, capital costs rose to $2.2bn. The company did not officially open …

Interest in replacing palladium catalysts with base metals resulted in the development of a 24-reaction screening platform for identifying nickel-catalyzed Suzuki–Miyaura reaction conditions. This method was designed to be directly applicable to process scale-up by employing homogeneous reaction conditions alongside stable and inexpensive nickel(II) …
The process of candidate selection involves an array of interviews, skills tests, psychometric tools, group discussions, and reference checks – all aimed at measuring the candidate's fitness for the role at hand. In spite of the incorporation of mobile-friendly AI-enabled tools to these processes, the selection process is being held back.

A further important use for electrodeposited nickel is electroforming. Nickel electroforming is the process by which nickel is built up by electrodeposition onto a suitable mandrel and subsequently removed to produce a nickel product which corresponds precisely to the shape and texture of the original substrate.
The methane dry reforming reaction can simultaneously convert two greenhouse gases (CH4 and CO2), which has significantly environmental and economic benefits. Nickel-based catalysts have been widely used in methane dry reforming in past decade due to their low cost and high activity. However, the sintering and coke deposition …

The Mond (or Carbonyl) Process is the most common and efficient method to treat nickel sulfide. In this process, the sulfide is treated with hydrogen and fed into a volatilization kiln. Here it meets carbon monoxide at about 140F° (60C°) to form nickel carbonyl gas. The nickel carbonyl gas decomposes on the surface of pre-heated nickel ...
Nickel is a ubiquitous metal added to jewelry and metallic substances for its hardening properties and because it is inexpensive. Estimates suggest that at least 1.1 million children in the United States are sensitized to nickel.
