Real-time quality control for the nickel ore mining industry

When integrated into the pyrometallurgical extraction process, the Sodern CNA-Nickel is an essential tool to control the nickel grade (the Fe/Ni ratio) and the basicity index (MgO/ SiO 2) of the material entering the kiln. As such, extraction process requires removal of all free moisture and combined water.
