数据集使用建议 在将此数据集整合到生命周期评估中时,应特别注意源自新疆省的镍铜钴矿的地理特异性,因为其环境影响可能与其他地区有显著差异。用户还应考虑采矿和浓缩的上游影响,以及与该生产过程相关的回收和废物处理的下游效应。必须明确定义排除标准,以避免重复计算,尤其是在考虑镍行业可能存在的闭环回收时。
产品或过程的技术目的 这种高冰镍生产过程涉及使用镍铜混合精矿通过火法冶金方法。这种高纯度的镍产品主要用于不锈钢、可充电电池和特种合金的制造。它在要求耐腐蚀和高温性能的材料生产中起着至关重要的作用。

技术代表性
技术说明,包括后台系统 鉴于地质和资源特征的复杂性,在采矿过程中采用了胶结回填法提取镍原矿,所选充填材料和粘合剂分别为尾矿和水泥。采矿过程中使用了地下施工机械(如凿岩机、扒渣机、电力机车和收割机)和地面施工机械(如塔式起重机、电焊机和卡车)。在选矿过程中,镍矿石由颚式破碎机、圆振动筛、球磨机、浮选机和浓缩机处理,以获得镍含量约为 8.6% 的镍铜混合精矿。随后,在火法冶金阶段对精矿进行处理,然后利用闪速熔炼技术将镍富集成高镍锍。在这一阶段,混合精矿首先在闪速炉中熔炼,以产生低镍锍,然后转炉将低镍锍吹成高镍锍和炉渣。炉渣被放入电清洗炉中生成低镍锍,然后将生成的材料再次放入转炉中。
