Method of producing ferro-nickel or metallic nickel |
| abstract |
A method of refining nickel from iron-rich nickel ore by adding silica therein, so that the silica may form fayalite with iron in the ore for suppressing the reduction of iron by taking advantage of the very low reducibility of fayalite. Silica to be added to the iron-rich nickel ore can be prepared by separating magnesia from nickel magnesium silicate ore, while using the exhaust gas from the nickel refining process as the source of carbon dioxide gas required for the magnesia separation. In this case, magnesia becomes a by-product of the nickel refining process. |
