THE APPLICATION OF THE CESL NICKEL PROCESS TO LATERITES

Manganese, another impurity of considerable importance in laterite ores, is precipitated as a hydroxide along with nickel and cobalt. Magnesium is partially precipitated along with the nickel and cobalt; typically only 5% of the magnesium in solution precipitates. The amount of magnesium precipitated is controlled by using a two-stage countercurrent

The Electrolysis of Magnesium: Magnesium

Due to its unstable and highly reactive nature, magnesium is refined through the process of electrolysis, whereby it is separated and extracted from its ore or solute form. A metallic object which violently reacts in contact with water and acids, magnesium's physical and chemical composition enforce the need for magnesium ores (or seawater solution) to be extracted through electrolysis.
