摘要:
锌焙砂一般采用中性-低酸-高酸三段浸出工序,该工艺在酸浸出中浸渣的过程中,铁也大量浸出进入到溶液中,加重了净化电积前除铁的负担。通过将传统锌湿法冶金工艺与氧压酸浸新工艺相结合,研究了氧压酸浸处理中浸渣的氧气压力、硫酸浓度、温度、浸出时间、粒度、液固比和分散剂等相关因素的影响。实验结果表明该工艺不仅提高了锌的浸出率(>98%),降低了铁的浸出率(<50%),缩短了生产周期,降低了生产成本,具有良好的经济效益;而且还具有环境友好和资源利用率高等优点,实现了简化工艺和节能减排的目的,为工业化生产提供了参考。
Abstract:
Zinc calcine leaching process by three stage,there are neutral leachinglow acid leachinghigh acid leaching.Iron would be leaching into the solution in the process of acid leaching which would increase the difficulty of remo ving iron before electro deposition.In this paper,the traditional zinc hydrometallurgical〖JP+1〗 and oxygen pressure leaching were combined.the effect of oxygen pressure、concentration of sulfuric acid、temperature、leaching time、m ineral particles size、liquor/solid ratio and amount dispersing agentwere found out from the research on oxidizing pressure leaching the residues from the neutral leaching process.The results showed thatoxidizing pressure leaching have good economic benefit and social effect.It is not only improve Zn leaching rate(over 98%),reduce Fe leaching rate(low 50%),shorten production cycle and reduction in production costs,but also environment friendly and raising resource utilization.So as to simplify process and save energymeanwhile it can offered reference for industrial study in future.
