Nickel and cobalt losses from laterite ore after the sulfation-roasting-leaching processing. 1 decade ago. This temperature can be lowered in the presence of a reducing agent, which reduces the energy requirement. Enthalpy of fusion: 8.7 kJ mol-1; Enthalpy of vaporisation: 128 kJ mol-1; Enthalpy of atomisation: 146 kJ mol-1; Thermodynamic data. An enthalpy of formation for MgSO 4 of −1284.9 kJ/mol was used in the calculations. The calculations resulted in a decomposition temperature of 625 °C, 600 and 610 °C in the presence of sulfur, carbon monoxide and hydrogen gas as a reducing agent, respectively.
