equipment development was needed in the completely new smelting concept, and specifically the novel smelting furnace (FSF) and its key equipment. Already from beginning, the very low use of external fuel and a superb sulphur fixation were evident. The need for a continuous development in ... thereafter for nickel, iron and lead sulphide ...
Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the …
In the current consumption of nickel, the iron and steel and non-ferrous metal smelting industries account for about 65% to 70% of the total nickel consumption. In light industry, bicycles, medical equipment, and daily necessities account for about 12% to 15% of the total consumption.
The two main pyrometallurgical methods used for nickel extraction are: 1) Nickel Smelting: Nickel smelting involves the heating and melting of nickel concentrates or nickel-containing ores along with fluxes and reducing agents in a furnace. The aim is to separate the nickel from the other components, such as iron, sulfur, and other impurities.

Smelting Equipment Heath & Sherwood designs and manufactures equipment used on the tuyère line of copper and nickel smelting furnaces such as Noranda Reactor, Pierce-Smith, Teniente and Hoboken type converters. Our tuyère line products have emerged from close working relationships with mining companies such as Noranda and Kennecott.
The main methods have been extensively reviewed for nickel extraction from nickel sulfide ores which maybe are potentially applicable to provide new ideas for smelting technology innovation of ...
The photos Minggu Bulu, the nickel worker I met last year, showed me still linger in my mind. They were of human ashes and bones. Broken legs. They belong to the former workers of GNI who were caught in accidents – whether in fire, in blasts, or in collisions – when they were working the nickel smelting equipment.
Experience of the direct Outokumpu nickel (DON) smelting process gained over the first ten years of operation is reviewed, including the significant environmental impacts. In 1995, production capacity at Harjavalta was increased from 17 000 to 52 000 t/year, by introducing DON technology, additional refinery capacity being based on …
Older nickel-smelting processes, such as blast or reverberatory furnaces, are no longer acceptable because of low energy efficiencies 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.
