| 中文摘要: |
| 基于矿物自动分析(MLA)技术，结合多种手段，对某硫化镍铜矿磨矿沉砂的进行了工艺矿物学研究。结果表明，沉砂主要由30%金属矿物和70%硅酸盐脉石矿物组成，其中目的元素镍、铜、钴、金、银、铂、钯含量分别为0.82%、1.10%、0.04%、0.75 g/t、10.50 g/t、0.23 g/t、0.13 g/t。独立的金矿物主要为合金相，独立的铂钯矿物包括合金相、砷化物和铋碲化物。金及铂钯矿物虽粒度细小，但部分已单体解离，且载体矿物大多为金属硫化物；银多以碲银矿形式赋存，碲银矿粒度细小，且银矿物大多呈包裹体分布于金属硫化物中。 |

| Based on mineral liberation analyzer (MLA) along with multiple other methods，the process mineralogical study of the grinding grit of a nickel-copper sulfide mine was carried out. The results show that the sand is mainly composed of 30% metal minerals and 70% silicate gangue minerals, in which the contents of target elements，nickel, copper, cobalt, gold, silver, platinum and palladium， are 0.82%, 1.10%, 0.04%, 0.75 g/t, 10.50 g/t, 0.23 g/t and 0.13 g/t，respectively. The independent gold minerals are mainly alloy phases while independent platinum-palladium minerals include alloy phases，arsenide and bismuth telluride minerals. Although the particle size of gold and platinum palladium minerals is small, some have been liberated and most of the carrier minerals are metal sulfides. Silver occurs in the form of hessite mineral and is capsuled in metal sulfides. The grain size of the hessite mineral is small. |
