, and the vanadium desorption rate can reach 99.6%. The max concentration of vanadium in desorbed solution can reach 20 g/L, while the concentration of molybdenum is less than 0.8 g/L. Key words: ammonium...(Ⅵ) and V(Ⅴ) completely, which results in a vanadium content in the range of 0.05%-0.20% in ammonium molybdate products. Traditional method of removing vanadium from molybdenum solution is precipitation......
Thermodynamic analysis on sodium carbonate decomposition of calcium molybdenum XIA Wen-tang(夏文堂), ZHAO Zhong-wei(赵中伟), LI Hong-gui(李洪桂) School of Metallurgical Science and Engineering, Central... of CaMoO4 reduces significantly in the presence of sodium carbonate. In order to achieve effective leaching of molybdenum from CaMoO4, a certain concentration of sodium carbonate is necessary. High total......

of 10 min, and organic-toaqueous phase(O/A) ratio of 1:1 with 10 vol% P204(D2EHPA). Molybdenum in the loaded organic phase can be effectively stripped with ammonium acid carbonate solution, and the stripping of molybdenum with 60 g L-1 ammonium acid carbonate solution is 94.67 % at O/A ratio of 2:1 and contact time of 10 min.关键词:......
