Home nickel and ferronickel milling and processing

The object of the invention is to provide a process for the recovery of iron and nickel from low iron content laterite ores. Said process comprises subjecting the ore to a carburizing step in the presence of a reducing agent and carbon supplying agent to convert the iron to iron carbide, followed by smelting the residue or product of the carburizing step to produce a ferronickel product.Industrially, the process is done either during dephosphorization or after dephosphorization and desulfurization. 7.4.3 Chromium. Chromium is present in ferronickel arising from smelting furnaces that operate with high contents of carbon in the feed. The chromium content in this type of ferronickel can be up to 1.7% (Bergman, 2003).It is removed during carbon oxidation with little loss of nickel.


Based on the process of coal-based self-reduction and melting separation at high temperature, it was investigated that the effect of process factors on the reduction of iron and nickel oxide, the metal yield and the nickel content in ferronickel about the laterite nickel ore, was from Philippines and contented low nickel, high iron and aluminum.What is claimed is 1. A process for producing crude ferronickel from lateritic ore comprising: 2. forming moist pellets 3/8 inch to 3/4 inch in diameter and consisting of uniformly blended finely divided lateritic ore and finely divided solid carbonaceous fuel, the amount of said fuel being only slightly more than stoichiometrically required to reduce the nickeliferous moiety of the ore;


Ferronickel is usually cast on conveyor machines in ingots of 25 to 35 kg weight. The specific energy consumption for processing 1 ton of dry lean nickel ore (1% Ni) is 810 kWh or 78 200 kWh per 1 ton of nickel. The use of richer ores (2.5% to 3.0% Ni) allows the decrease of specific energy consumption at least twofold ( Novikov et al., 2005 ).This web page summarizes information in PubChem about patent AU-2008237569-A8. This includes chemicals mentioned, as reported by PubChem contributors, as well as other content, such as title, abstract, and International Patent Classification (IPC) codes.
