Calcination of Nickel Mud

Different characterizations were carried out on uncalcinated nickel mud and samples calcined in the temperature range of 200–600 °C. In the present paper, the phase composition and structure transition of the nickel mud heated from room temperature are indicated by SEM, EDX analysis and Fourier transform infrared spectroscopy. Samples of nickel mud were collected in Sereď, where nickel was produced from Albanian iron-nickel ore. It was found that calcination has effect on the structure and composition of nickel mud. The obtained results provide an important base for the further studies of comprehensive utilization of nickel mud.
