| 摘 要： | 采用45%H2SO4溶液作为浸出剂浸出含钒云母,研究了其溶解行为。结果表明:在浸出过程中,含钒云母矿物晶格原子键能、键长、电荷平衡以及分子构型发生变化;矿物中V、Al元素在H2SO4中浸出过程中表现出溶出行为一致,以等速率从固相中溶蚀释放出来;V、Al元素溶出率与矿物晶面间距密切相关。

| Abstract: | The 45% sulfuric acid solution was used as a leaching agent to leach vanadium-bearing mica in an experiment for investigating its dissolution behavior. The results showed that the lattice atomic bond energy, bond length, charge balance and molecular configuration of vanadium-bearing mica minerals changed during the leaching. The elements of V and Al in the minerals, presenting the same dissolution behavior during the leaching with sulfuric acid, were leached from the solid phase at the same dissolution rate, which was found to be closely related to the interplanar spacing in the mineral lattice structure. |
