Nickel production through the Caron process

The Caron process is one of the processes used to extract nickel from nickel laterite ores. The Caron process combines both hydro- and pyrometallurgy processes which include: reduction roasting of laterite ore, leaching of roaster product, precipitation of basic nickel carbonate (BNC), and decomposition of BNC followed by reduction of nickel oxide. The current presentation will discuss the research carried out by the authors at the final stages of Caron process, i.e. BNC decomposition and NiO reduction, in support of improvements in nickel production process through this process.
