我国南方下寒武统含钒石煤是一种新型钒矿资源,本文对浙江鸬鸟石煤及其风化样,采用化学物相分离及电化学分析法测定了钒的赋存价态,研究了石煤氧化焙烧过程中钒的价态变化及其分布规律。实验表明,NaCl对鸬鸟石煤中钒的氧化和转化作用不甚明显,不适宜采用钠盐氧化焙烧提钒工艺。根据鸬鸟石煤的特点,提出了先酸浸后氧化的提钒工艺。
The Lower Cambrian vanadium-containing stone coal in southern China is a new type of vanadium ore resources. In this paper, the petriferous coal and its weathering samples of Zhejiang Province were determined by chemical phase separation and electrochemical analysis. Valence Variations and Distribution of Vanadium in the Process of Oxidative Roasting of Stone Coal. Experiments show that NaCl on cormorant stone anthracite vanadium oxidation and transformation is not obvious, not suitable for sodium oxidation roasting vanadium extraction process. According to the characteristics of cormorant stone coal, proposed acid leaching and oxidation of the vanadium extraction process.
