The Caron Process
A steadily increasing demand for nickel has without doubt raised the importance of the worlds nickel reserves and applied more focus on the techniques used for extraction of nickel from its ores. The Caron Process is one such technique which is effective by reduction of the ore by roasting followed by ammonia leaching of the reduced ores.
