熟化银精矿氧压强化酸浸行为研究OA北大核心CSTPCD
Enhanced acid leaching behavior of curing silver concentrate by oxygen pressure
考虑到浮选银精矿极具回收价值及现有处理工艺存在不足,本文提出了浓硫酸熟化-氧压酸浸的工艺路线.首先,以湿法炼锌过程产出的浮选银精矿为对象,利用浓硫酸的强氧化性破坏浮选残留有机药剂矿物包裹体;其次,利用加压湿法冶金独特的技术优势,氧化溶解低价金属硫化物;最后,重点研究了工艺过程原理及氧压酸浸过程中Zn、Cu、In的浸出行为及浸出渣中物相演变规律.研究结果表明:银精矿颗粒表面残留浮选药剂的P—O、—OH极性基团被浓硫酸氧化破坏,避免产生水化膜及矿物包…查看全部>>
In view of the high recovery value of flotation silver concentrate and the shortcomings of existing treatment technology,the technological route of sulfuric acid curing oxygen pressure acid leaching was put forward.Firstly,the flotation silver concentrate produced in zinc hydrometallurgy process was taken as the research object,and the strong oxidation of concentrated sulfuric acid was used to destroy the flotation residual organic reagent mineral inclusions…查看全部>>
