  • Effect of calcination condition on the performance of iron ore in ...

    2020年6月15日  In this study, a natural iron ore was treated under the combined effect of three key calcination parameters (heating rate, temperature, and duration time). The reactivity performance of calcined iron ores was evaluated with CO as fuel, and the iron 2016年5月10日  This work presents the results of bench calcination and sintering studies conducted on an iron ore sample from Iron Quadrangle, Brazil with high goethite Bench-scale calcination and sintering of a goethite iron ore sample ...Calcination is thermal treatment of a solid chemical compound (e.g. mixed carbonate ores) whereby the compound is raised to high temperature without melting under restricted supply of ambient oxygen (i.e. gaseous O2 fraction of air), generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition. The root of the word calcination refers to its most prominent use, which is to remove carbon from Calcination - Wikipedia
