英文摘要: Abstract(#br)The authors have developed a process for the direct production of the rare earth elements oxides (REO) through the calcination of a raw ore that contains carbonate minerals, such as bastnaesite (a known REE bearing carbonatite) and gangues (e.g., calcite, dolomite, siderite, and ankerite). Due to the complexity of the ore, an elaborated kinetic study was required to gain an insightful understanding of the contribution of each mineral to the overall reaction kinetics. Thus, calcination kinetics of individual carbonates was investigated by thermogravimetric analysis, and subsequently new as well as modified kinetic models were developed.(#br)The comparison of kinetic parameters and decomposition conditions of bastnaesite and gangue minerals revealed that the calcination of...
