Calcination Wikipedia
In limestone calcination, a decomposition process, the chemical reaction is CaCO 3 → CaO + CO 2 (g) The standard Gibbs free energy of reaction is approximated as ΔG° r ≈ 177,100 − 158 T (J/mol) The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K, or 848 °C Oxidation In some cases, calcination of a metal results in oxidation of the metalThe nickel and cobalt are separately reduced to metal products The flowsheet below shows the unit operations used in the process Source: Acid Leach ProcessMETMOC; NickelProcess; The main source of the world's nickel is from coppernickel sulphide ores with those mined at Sudbury, Ontario being by far the most extensiveNickel: smelting, producingMetalpediaFrom its varying composition, to its abrasive nature, limestone requires an engineered process solution, combined with heavyduty equipment That’s why we not only offer limestone processing equipment, but can also help develop a limestone process that works around your unique source of limestoneLimestone Processing
