Treatment of non-sulfidic nickeliferous resources and recovery of metal values therefrom |
| abstract |
A process for nickel concentration and extraction from non-sulfidic iron-bearing nickeliferous resources is disclosed. The process includes an atmospheric acid-based leaching treatment of the non-sulfidic iron-bearing nickeliferous resources by oxalic acid to produce a nickel concentrate comprising distinct nickel oxalate particles. The nickel concentrate is technically amenable to further chemical and physical processing to obtain various high-grade nickel products. |
