0.2-2% nickel, to an acceptable concentrate grade of 10 to 20% nickel.[2,11] Concentrate smelting produces a high grade nickel matte which is then refined hydrometallurgically. [2,12] With the majority of the world's nickel supply coming via pyrometallurgical processes, the technology has proven to be quite robust over the years.

This leads for a need to close the process water circulation. To see the effect of closed water circulation on metallurgical performance, flotation tests were carried out with nickel concentrate thickener overflow water before and after the process of water purification by dissolved air flotation (DAF).

Nickel sulfide concentrates are critical materials for the production of metallic nickel. The disadvantages associated with the conventional nickel extraction process are the considerable amounts of sulfur dioxide emissions in the smelting process and the complex Ni refining steps to produce a marketable product. The authors proposed a …

Vale's hydromet technology to process the Voisey's Bay nickel concentrate at Long Harbour was the end-product of a 10-year, $200-million R&D program that began with laboratory work and the operation of a 1-10,000 scale mini-pilot plant at the company's Mississauga, Ont. research centre and the operation of 1-100 scale demonstration plant ...
