Abstract:
Effect on the content of fluorine in gas of decomposition course of mixed rare earth preparation concentrate on CaO is studied. The content of fluorine is measured by the gas chromatographic analysis method,the results show CaO can absorb the fluorine in the decomposition course of mixed rare earth perparation concentrate,and the 60% content of fluorine in the gas of is absorbed.The result of XRD experiment of roasting production of bastnaesite added 15% CaO shows there is a great deal of CaF2 in the roasting production. This shows the absorbing fluorine mechanism of CaO in the decomposition course of mixed rare earth preparation concentrate is that CaF2 is generated by the chemical reaction of CaO and REOF. |
