摘要
研究了助浸剂对某矿山钒矿直接酸浸的影响。试验结果表明,添加5%HJZ-1#、5%HJZ-2#混合添加剂,钒的浸出率可从47.58%提高到85.31%。钒矿浸出渣工艺矿物学研究表明,助浸剂的加入有利于难溶硅酸盐包裹中钒的浸出,从而提高钒的浸出率。
The effect of leaching agent on sulphuric acid leaching of a vanadium ore was investigated.The result showed that the leaching rate of vanadium by sulphuric acid leaching can be increased from 47.58％ to 85.31％ by the addition of 5％ HJZ-1# and 5％ HJZ-2# as combined leaching agent.The study of process mineralogy of the leaching residue showed that vanadium wrapped in the indissolvable silicate was leached by the addition of leaching agent,so the leaching rate of vanadium was effectively improved.
