    印度尼西亚某红土镍矿中铬的分离回收试验研究

    Experimental study on the separation and recovery of chromium from a laterite nickel mine in Indonesia

    • 摘要: 某红土镍矿位于印尼北部地区,原矿含铬2.18%、钴0.11%、镍1.04%。为提高矿山的经济效益,并降低含铬矿物对后续钴、镍冶金过程的干扰,采用重-磁联合工艺对该红土镍矿中的含铬矿物进行分离回收试验,经“洗矿-旋流器-螺旋溜槽-二级摇床-弱磁-强磁”流程,最终获得含铬33.45%、铬回收率为40.23%的合格铬精矿,矿石中的钴、镍在该铬精矿中的损失率分别为1.74%和0.33%,有效实现了对该红土镍矿中铬的分离回收。

       

      Abstract: A laterite nickel mine is located in the northern region of Indonesia. The raw ore contains 2.18% chromium, 0.11% cobalt, and 1.04% nickel. In order to improve the economic benefits of the mine and reduce the interference of chromium containing minerals on subsequent cobalt and nickel metallurgical processes, a gravity-magnetic combined process is used to separate and recover the chromium containing minerals in the laterite nickel mine. Through the process of “ore washing-cyclone-spiral-secondary shaking table-weak magnetic separation-strong magnetic separation”, a qualified chromium concentrate with a chromium content of 33.45% and a chromium recovery rate of 40.23% is obtained. The loss rates of nickel in the chromium concentrate are 1.74% and 0.33%, respectively, effectively achieving the separation and recovery of chromium in the laterite nickel ore.
