US3661564A - Extraction of cobalt and nickel from laterite A method for the recovery of nickel and cobalt from laterite with the elimination of iron wherein the laterite is divided into a major and a minor portion and the minor portion is treated with hydrochloric acid to form a suspension.
Extraction of nickel and cobalt from nickeliferous limonitic Inspired by the matte production process this study aims at extracting nickel and cobalt from laterite ores through a direct smelting process. More specifically the possibility of achieving high extraction recoveries of nickel and cobalt and producing a high grade nickel matte at low smelting temperature was investigated.
Cobalt extraction - Wikipedia The hydrometallurgical process for laterite ore can use sulfuric acid or ammonia leach solutions. Similar processes for the extraction of cobalt have been proposed using manganese nodules as a feedstock.
Extraction of cobalt from laterite ores by citric acid in Citric acid was used to selectively extract cobalt from limonite-type laterite ores in the presence of ammonium bifluoride. The results show that ammonium bifluoride enhances the leaching of cobalt by citric acid and 84.5% cobalt is extracted from a laterite ore containing 0.13% Co when leached at ambient temperature for 2 h with 30 g/L citric acid and 10 g/L ammonium bifluoride.
