摘要: 用直接酸浸法从湖南湘西某石煤钒矿的底层石煤中提取了钒,研究了加入3种氟化物助浸剂对浸出的影响。采用XRD、SEM考察了浸出渣的晶型与颗粒形貌,用ICP-AES法测量了浸出液中18种元素的含量。对助浸剂为氟化钠、氟化钙的2种浸出液分别进行了进一步的提钒研究,对提钒各步溶液做了ICP-AES测试,以检测每一步提钒步骤对钒的提取以及对各种杂质元素的去除情况。

关键词: 钒, 石煤, 酸法直接浸出, 氟化物助浸

Abstract: Vanadium was extracted from stone coal which was got from the bottom layer of a stone coal vanadium ore in the West of Hunan Province by direct acid leaching technology with three kinds of fluoride aid-leaching reagents.Structures and morpho- logies of leaching residue were studied by XRD and SEM,and contents of 18 kinds of elements were measured by ICP-AES experiments.Further vanadium extracted study was carried out with NaF and CaF2 as aid-leaching reagents,respectively.Ex- tracting of vanadium and removal of impurities in each step were studied by ICP-AES experiments of solutions in every step.

Key words: vanadium, stone coal, direct acid leaching, fluoride aid-leaching
