Ferronickel Production From Oxide Nickel Ore

Nov 01, 2002 Mintek has been working on the production of unrefined ferronickel from nickel-containing lateritic ores and dust in DC-arc furnaces since 1993. The development and various advantages of the DC-arc furnace technology developed at Mintek has previously been described in detail (Jones et al., 1993 Lagendijk et al., 1994). In essence, nickel-containing lateritic material, together with a.

Smelting Of Nickel Oxide Ores To Produce Ferronickel

Ferronickel is produced from nickel oxide ores, such as those of the laterite or serpentine types, in a cyclic smelting process using a carbon reductant. In the first stage of the cycle, carbon reductant is added to the furnace charge in sufficient amount to form a nickel-depleted slag and a.

Production Of Ferronickel From Nickel Laterites In A Dc

Mintek has been working on the production of unrefined ferronickel from nickel-containing laterite in DC-arc furnaces since 1993. In this process, lateritic material is fed, together with a carbonaceous reducing agent, to the central region of the molten bath of a cylindrical DC-arc furnace. This feed material is preferably pre-treated, i.e. hot (calcined), and optionally pre-reduced.
