with carbon as reductant, chlorine gas as chlorination agent, and SiCl4 as de-fluorination agent. The XRD analysis result shows that the residues obtained at 750 ℃ are SiO2 and monazite. Key words...,即反应(4)和(5)在热力学上比反应(2)和(3)更有利.稀土氟化物不溶于水或 图1 尾矿氯化反应与温度的关系 Fig.1 Evolution of standard free energy changes as function of temperature for chlorination and metathesis of some compounds......
for fluidizing chlorination process with respect to impurity contents. After a pre-oxidation at around 1 042 °C and a heat-treatment above 1 510 °C, the Ti components in high titania slag can be enriched... as a raw material for a pigment production by the chlorination process because of the large amount of impurity, such as SiO2, Al2O3, CaO, MnO, V2O5 and MgO, especially, the high CaO and MgO contents......
, impacts of MIEX prior to coagulation on coagulant demands and the effectiveness of combination of MIEX, pre-chlorination and coagulation were investigated. Kinetic experimental results show that more... organics removal as a target. MIEX can remove organics to a greater extend than coagulation and lower the coagulant demand when combining with coagulation. Chlorination experimental results show that MIEX......
Received 15 January 2020; accepted 16 June 2020 Abstract: A novel molten salt extraction process consisting of chlorination roasting and molten salt electrolysis was proposed to develop a more efficient... health risks and equipment corrosion. Consequently, developing a more efficient and environmentally-friendly technology for spent LABs recycling appears to be particularly important. Chlorination......
