镍钼矿选矿工艺分析

Analysis of nickel molybdenum ore beneficiation process

镍钼矿选矿是有价元素提取的关键过程,会为后续矿产资源开发奠定基础。本案例中的镍钼矿中镍含量为0.52%、钼含量0.74%,呈现出集合产出形态。为实现对矿产资源的良好开发,按照工艺流程脱质后,将CMC作为抑制剂,使用浮选工艺处理,选矿实验得到的镍、钼回收率,分别为81.22%、72.55%,有利于降低后续矿产焙烧投入的成本,提高镍钼矿冶炼效率。

Nickel molybdenum ore beneficiation is a key process for extracting valuable elements,which will lay the foundation for subsequent mineral resource development.In this case,the nickel molybdenum ore has a nickel content of 0.52%and a molybdenum content of 0.74%,showing a collective production pattern.In order to achieve good development of mineral resources,CMC was used as a depressant after the process flow was carried out,and flotation technology was used for treatment.The recovery rates of nickel and molybdenum obtained from beneficiation experiments were 81.22%and 72.55%,respectively.This is beneficial for reducing the cost of subsequent mineral roasting investment and improving the smelting efficiency of nickel molybdenum ore.
