摘要
采用高压酸浸法从Ramu镍红土矿中回收镍钴。详细介绍了矿浆处理、高压酸浸、循环浸出及矿浆中和、CCD逆流洗涤、中和除铁铝、氢氧化镍钴沉淀、深海填埋工艺(DSTP)等流程,并分析了工艺出现的问题及改进措施。全流程镍回收率～96%,钴回收率～94%。
Nickel and cobalt were recovered hing technology. （HPAL）, cycling moval with neutra ment （DSTP）. T The process introduced from Ramu laterite type in detail includes slurry leaching and slurry neutrali lization, precipitation of nic he problem were put forward. The recove zation, CCD c kel hydroxide nickel treatm ountercurrent ore with high press ent, high pressure washing, iron and ure acid leac- acid alumi leaching hum re- and cobalt hydroxide, deep sea railings place presented in the process was investigated and improvement measurements ry rate of nickel and cobalt are -96% and -94% respectively.
