the effect of sulfur in rotary kiln fuels on nickel

1 day ago According to an October 2019 Araguaia feasibility study, the projects initial production phase would produce 900,000 tonnes per annum of ore for treatment in a rotary kiln electric furnace to produce about 14,500 tonnes per year of nickel contained in 52,000 tonnes per year of ferronickel. Araguaia will also produce substantial volumes of cobalt. Unishine Machinery has rich experience in the production of large-scale kiln and powder grinding equipment, we can provide 300-1500 tons of rotary kiln equipment. At present, the company has installed more than 100 sets of rotary kilns of various specifications, which are sold well in China and exported to Vietnam, uzbekistan, Pakistan and ...

production of ferronickel from nickel laterites in a dc

SNNC, Socit du Nickel de Nouvelle Caldonie et Core, started up its new ferronickel smelter in the third quarter of 2008, and in early 2009 completed ramp-up of the furnace to its full design production level. The plant is based on the rotary kiln electric furnace (RKEF) process, with two rotary kilns and a single a large furnace to achieve economies of scale in capital and ... introduced to the diesel-fired rotary kiln, producing excellent quality calcine with very little dust generation. Hot calcine at about 800. 0. C was transferred to the electric furnace for smelting to ferronickel of pre-determined nickel grade and a low nickel slag. The ferronickel was periodically tapped and either cast as ingots or granulated.

Araguaia will also produce substantial volumes of ...

sulfur deportment in ferronickel production via rotary

The rotary kiln-electric furnace (RKEF) process is a pyrometallurgical route that has long been used for the production of ferronickel. Since the presence of impurities would have negative effects on the properties of ferronickel, it is necessary to control the form and concentration of impurities. Ferronickel. The rotary kiln and electric furnace process has long been the most commonly employed method of recovering nickel from saprolitic laterite ores. Production improvements have been achieved over the years by the adoption of shielded arc smelting and the installation of water-cooled copper cooling elements in the furnace sidewalls.

Dehydration as a minimum, and some pre-reduction of the ore in a rotary kiln is used to optimize the utilization of electric energy for smelting operations in the conventional submerged-arc furnace process. During the dehydration of the ... ferronickel originates from the coal added as the fuel and the reductant during calcination in the rotary kiln. This study investigates the role of sulfur content of rotary kiln fuels on the composition of the calcine. The calcination-partial reduction experiments were conducted in a

different application of rotary kiln

In the conventional production of ferronickel from these ores, ... ( 100 m) from an industrial rotary kiln calciner (for two tests), and laterite ore fines ( 6 mm) dried at 250C (also for two tests). Charcoal ( 4 mm) was used as the reductant in all these tests.
