In both calcination and roasting an ore is converted into its oxide albeit through different chemical pathway Calcination is the process in which the ore is heated below its melting point Calcination The IUPAC defines calcination as heating to high temperatures in air or oxygen However calcination is also used to mean a thermal treatment process in the for example gold was calcined in a reverberatory furnace with mercury and sal assay of gold ore
اتصل بناCalcination Roasting Calcination is a process in which an ore is heated in the absence of air or air might be supplied in limited quantity Roasting involves heating of ore higher than its melting point in the presence of air or oxygenRoasting the presence of air This method is employed Calcination Ore is heated stongly Ore is heated strongly in in the absence or lirnited supply of air This method is employed for carbonate for sulphide or ores CO2 gas is produced
