摘　　要：依据GB/T 2007.3-1987标准要求对10交货批散装红土镍矿进行了品质波动试验,得出特性值镍的标准偏差估计值σW在0.10-0.23之间,据此将品质波动划分为"大"、"中"和"小"三种类型,σW≥0.20%为"大"、0.20>σW>0.15为"中"、σW≤0.15为"小"。According to GB/T 2007.3-1987 standard requirements, the quality variation test of ten lots of laterite nickel ore in bulk were carried out. The results of characteristic value, nickel standard deviation estimator were between 0.10 and 0.23. It was divided into “large”, “moderate” and “mild”. Those were ≥0.20% for the “large”, 0.20〉 and 〉0.15 for “moderate”, ≤0.15 for“ mild”.
