中文摘要: 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%。
Abstract:Nickel and cobalt were recovered from Ramu laterite type nickel ore with high pressure acid leaching technology. The process introduced in detail includes slurry treatment, high pressure acid leaching (HPAL), cycling leaching and slurry neutralization, CCD countercurrent washing, iron and aluminum removal with neutralization, precipitation of nickel hydroxide and cobalt hydroxide, deep sea tailings placement (DSTP). The problem presented in the process was investigated and improvement measurements were put forward. The recovery rate of nickel and cobalt are ~96% and ~94% respectively.
