Nickel　is　widely　used　in　stainless　steel　and　other　industries,　while　there　are　a　lot　of　energy　consumption　and　environmental　pollution　in　the　process　of　nickel　production.　Based　on　the　technical　framework　of　life　cycle　assessment　and　evaluation　model　of　ReCiPe,　the　aim　of　this　paper　is　to　find　out　the　environmental　hotspot　and　make　suggestions　for　improvement　by　researching　the　environment　inpact　of　nickel　production　from　the　process　of　mining,　beneficiation,　smelting　and　transportation.　The　result　shows　that:　Smelting　is　the　most　important　environmental　effect　stage　in　which　the　environmental　impact　load　accounts　for　52.18%　of　total　environmental　impact,　because　a　lot　of　electricity　is　consumed　in　electrolysis　process,　while　the　Fossil　Depletion　Potential　(FDP)　is　the　largest　environmental　impact　type,　accounting　for　42.32%　of　total　environmental　impact,　which　is　due　to　the　consumption　of　a　number　of　fossil　energy　in　the　mining　and　smelting　process　of　nickel　ore.　It　is　necessary　to　use　advanced　mining　technology　and　mine　backfill　technology　to　reduce　the　consumption　of　auxiliary　materials,　which　is　of　great　significance　for　reducing　energy　consumption　and　emission.　©　2018　Trans　Tech　Publications,　Switzerland.
