Converters must be co-ordinated with ash furnaces which melt and temporarily store solid ore. E cient co-ordination of planning, scheduling, and resource allocation is crucial toward optimizing the process economics. The converter aisle of a nickel smelting plant is comprised of both discrete
This article presents data on nickel sulfide smelting, gathered from a survey of the 19 world nickel sulfide smelters. The feed to these smelters normally consists of a nickel-copper concentrate, also containing minor amounts of cobalt and platinum group metals (PGMs). In most African smelters, South Africa in particular, nickel is in fact a ...

and volatiles. Older nickel-smelting processes, such as blast or reverberatory furnaces, are no longer acceptable because of low energy efficien-cies and environmental concerns. In flash smelting, dry sulfide ore containing less than 1% moisture is fed to the furnace along with preheated air, oxygen-enriched air (30–40% oxygen), or pure oxygen.
· INTRODUCTION 1.1 Process Description The Nickel smelting process uses mineral rich ore that is smelted in flash furnaces to produce flash furnace matte (FFM) with 45-47% CuNiCo. The FFM is tapped and then transported by means of cranes and ladles to the Converter Aisle where enriched air is blown through tuyeres in PeirceSmith converters to ...

· Seventy-five percent sulfur dioxide is regularly produced by flash smelting copper concentrate, using pure oxygen, at the Sudbury, Ontario, smelter of the International Nickel Company. In this plant (the only flash smelting process in the Western Hemisphere) copper concentrate is smelted to about 45-percent matte.
· The average chemical composition of the ore processed in the smelter plant is presented in Table 1 (Boev and Bermanec 2005). The smelter plant produces about 16,000 t of nickel in the form of ferronickel with a Ni content of 25 to 40 %.

Copper and/or nickel sulphide ore concentrate of high intrinsic energy is smelted by exothermically reacting the ore concentrate with oxygen in an oxidation station (29) to produce the metal, or a low-iron matte, and sulphur dioxide. The metal or low-iron matte is recovered via line (34). Sulphur dioxide removed from the oxidation station (29) is passed via a fluidised bed (38) to a sulphation ...
plant or unit is operating, to be calculated as a proportion of annual operating hours.

Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...
In Nickel Flash Smelting technology, sulfide nickel concentrate is processed in the Outotec ® Flash Smelting Furnace to produce nickel matte and slag. The matte is transported to the Peirce-Smith converters where it is blown to high-grade matte. The metal values in the smelting and converting slags are recovered in the electric furnace as ...
