direct reduction plant ferronickel

direct reduction plant ferronickel Home direct reduction plant ferronickel The invention relates to the field of non-ferrous metallurgy and specifically to a method for processing laterite (oxidized nickel) ores with the direct production of ferronickel in the form of metal granules

Ferronickel an overview ScienceDirect Topics

The product is refined ferronickel, which contains 20%–40% Ni and 80%–60% Fe. The ferronickel is suitable for making stainless steel and other ferrous alloys. The feed is predominantly saprolite, rather than limonite. This is because the iron content of the saprolite ore, about 15% Fe,

Direct Reduction Plant Products || KOBE STEEL, LTD.

Recently, while the production of steel via the Blast Furnace route are increasing only slightly, production via the Direct Reduction Plant route have dramatically increased. (From around 800,000 tons per year in 1970 to around 55,000,000 tons per year in 2005.)

Pilot plant production of ferronickel from nickel oxide

In the conventional production of ferronickel from these ores, much fine material is produced which cannot readily be accommodated directly in existing three-electrode or six-in-line AC furnaces. DC-arc furnace technology allows ore particles less than 1 mm in size to be treated directly thereby improving the overall recovery of nickel without the need for expensive agglomeration techniques.

Ferronickel Production From Oxide Nickel Ore

Ferronickel Production From Oxide Nickel Ore. ore briquette the main reactions of nickel oxide to metallic nickel are as follows 14 1 2 3 The initial temperature of NiO reduction by xed carbon is about 440176C at the atmospheric pressure and the standard Gibbs free energy of reaction 3 is negative at the standard atmospheric pressure Therefore NiO is easily reduced by CO

Two-stage reduction for the preparation of ferronickel

The preparation of ferronickel alloy from the nickel laterite ore with low Co and high MgO contents was studied by using a pre-reduction–smelting method. The effects of reduction time, calcination temperature, quantity of reductant and calcium oxide (CaO), and pellet diameter on the reduction ratio of Fe and on the pellet strength were investigated. The results show that, for a roasting

[PDF] Pilot plant production of ferronickel from nickel

Abstract Laterites and other oxidized nickel ores constitute a very important part of world-wide nickel reserves. The development of nickel oxide ore smelting has drawn heavily on iron and steel metallurgy. In ferronickel production, the nickel oxide and part of the iron oxide are reduced to metal in an electric furnace to form immiscible layers of slag and metal.
