To study the distribution of Ni emission to air from the myriad of point and diffuse sources within a plant site is a complex sampling and analysis problem. However, it provides important underlying information for source abatement. At a Ni refinery

Battery production for electric vehicles has increased rapidly in the last decade, and the projections show an ever-increasing demand for the next years. This leads to a need for recycling of valuable metals used in batteries, such as nickel, for a s

Iron removal in the nickel industry is achieved by precipitation and filtration, and for enhanced process efficiency, the filtration step must be improved. A mixed-suspension-mixed-product-removal (MSMPR) reactor set-up operating at steady-state was

Ferric iron removal from the nickel electrolyte at Glencore Nikkelverk AS in Kristiansand, Norway, is achieved by precipitation of iron hydroxide followed by filtration, and it is desirable to improve filtration properties of the precipitated iron hy

Basic cobalt salts redissolve more easily than Co alloys; this is the major reason for cobalt redissolution during the technical purification of the zinc sulphate electrolyte before zinc electrolysis. The electrolysis is performed using a very pure z

Micro-Raman spectroscopy is used to characterize the cemented product formed during cobalt cementation with zinc dust in zinc sulfate electrolytes. The effect of copper and antimony on the cementation process is also examined. A Raman spectrum charac

The observed removal of Co 2+ during cementation on zinc is due to two reactions. One reaction is formation of a Co alloy or Co in solid solutions. The second reaction is formation of basic cobalt salts, and is a function of local high pH at the zinc
