AN INTRODUCTION TO OUTOTEC FLASH SMELTING With flexibility, low energy consumption, high sulfur capture, and excellent economy of scale, Outotec Flash Smelting technology is the world''s leading method for copper and nickel smelting. More than half of the world''s primary copper and nickel is produced using Outotec''s proprietary process.
A nickel flash smelting furnace is initially used to obtain the valuable metal but the loss of nickel in the slag amounts to about 4 % and thus an electric slagcleaning furnace has to be subsequently used to reduce the loss of the valuable metal to less than % nickel oxide in the slag.
Producing bulk concentrates and treating them by Outotec Direct Nickel Flash Smelting (DON) to matte and then hydrometallurgical refining, offers a reliable route from concentrate to product. In the DON process high grade matte with low Fecontent is produced in the Flash smelting furnace (FSF) and metal values in slag are recovered in an ...
Outokumpu Harjavalta Metals Oy has been producing nickel since 1962, based on conventional flash smelting technology followed by electrowinning of nickel. In the 1980s, a research project was initiated to develop a converterless direct smelting process to produce matte for further refining in the then existing refinery. The process was tested on a pilot plant...
An innovative process Koniambo Nickel. Smelting occurs in an electric furnace heated to 1600 degrees, and ferronickel is periodically tapped into ladles. As for the slag, it is tapped continually at 1600°C into 30 m 3 slag pots and hauled to the slag disposal area. Fresh water in a closedcircuit system cools some parts of the furnace.
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 PeirceSmith converters where it is blown to highgrade matte. The metal values in the smelting and converting slags are recovered in the electric furnace as ...
Flash smelting (Finnish: Liekkisulatus, literally "flamesmelting") is a smelting process for sulfurcontaining ores including process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production.. A second flash smelting system was developed by the International Nickel ...

Outotec Flash Smelting Process The Outotec Direct Nickel Flash Smelting Process was first implemented at Harjavalta Smelter in Finland. Simultaneously with the adoption of the new process, the nickel production was doubled. The entire target of the project was to improve the profitability, cut sulphur dioxide emissions, improve the
smelting of coppernickel concentrates in a MVA furnace with six inline electrodes. The matte and slagtapping temperatures, slag temperatures, slag analyses, electrical data, and electrode position were measured. Radioactive tracers were introduced into the slag, and quantitative results relating to the flow pattern within the furnace ...
The goal of this study was to investigate the distribution of trace elements (Ge, Co, Se, Pb and Sn) between nickel matte and fayalite slag in the Direct Outotec Nickel Flash Smelting – process. The experiments were conducted with a method that includes equilibration and quenching of the sample, followed by an EPMAanalysis.
A thermodynamic model has been developed to predict the distribution behavior of Ni, Cu, Co, Fe, S, As, Sb, and Bi in the Outokumpu flashsmelting process, the Outokumpu direct highgrade matte smelting process, and the INCO flashsmelting process. In this model, as many as 16 elements (Ni, Cu, Co, Fe, As, Sb, Bi, S, O, Al, Ca, Mg, Si, N, C, and H) are considered, and two nickel sulfide ...

Most of South Africa''s nickel is produced as a byproduct of platinum mining activities on the Bushveld Igneous Complex. South Africa is about the tenth largest producer of nickel in the world with a production of about 42,000 metric tonnes in 2011 [1]. Slag generated in the direct nickel flash smelting .
Industrial nickel slag from the direct Outotec nickel flash smelting (DON) process was mixed with both synthetic and industrial battery scrap. The end products of the slagscrap mixtures after ...
flash smelting. Flash smelting is the most common process but electric smelting is used for more complex raw materials when increased flexibility is needed. Both processes use dried concentrates. Electric smelting requires a roasting step ahead of the smelter to reduce sulfur content and volatiles. Older nickel smelting processes, such as blast or
Nickel, a naturally occurring element, is ubiquitous in the environment, especially in the divalent state. It was identified in the middle of the 18th century and its extraction process developed in the middle of the 19th century. In Finland, primary nickel production takes place by the direct highgrade nickel matte flash smelting process.

In the DON process, high grade nickel matte of low iron content is produced in the flash smelting furnace directly without subsequent converting. The metal values in the smelting slag are recovered in an electric furnace as an iron containing Ni matte.

Realizing that the concentrate contains ahigh percentage ofmagnesium, they immediately focused their attention onelectric smelting, where high operating temperatures could be tolerated. A further attraction wasthat power costs inthe Republic ofSouth Africa are fairly Iowatabout RO,OSper kW hand
