Extraction of cobalt from laterite ores by citric acid in ...

Aug 01, 2010  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.

History. Ores containing cobalt have been used since antiquity as pigments to impart a blue colour to porcelain and glass. It was not until 1742, however, that a Swedish chemist, Georg Brandt, showed that the blue colour was due to a previously unidentified metal, cobalt. In 1874 the output of cobalt from European deposits was surpassed by production in New Caledonia, and Canadian ores assumed ...

Sep 06, 2019  The ore is mixed with calcium oxide and silica, producing a slag. This makes it possible to separate silver, a mixture of materials rich in copper, nickel and cobalt and a scorifiable residue. This mixture rich in copper, nickel and cobalt is what is technically called “speiss”. Getting from this mixture to the pure metal is a complex process.
