基于选冶固废的新型充填材料开发及应用

(Summary description)针对金属矿山充填成本高、选冶固废堆存存在潜在环境风险等问题,开展基于选冶固废的新型胶凝材料研发,现已成功开发一系列基于不同选冶固废的新型胶凝材料,可根据矿山实际情况定制开发适用,部分技术或产品现已经在权属矿山得到应用。针对紫金山金铜矿,开发了一种替代水泥的新型胶凝材料,具有早期抗压强度大、沉缩率小的特点,远优于同等条件下水泥的性能。针对贵州紫金,在满足充填抗压强度的要求下,充填浓度可提高110%,

  针对金属矿山充填成本高、选冶固废堆存存在潜在环境风险等问题,开展基于选冶固废的新型胶凝材料研发,现已成功开发一系列基于不同选冶固废的新型胶凝材料,可根据矿山实际情况定制开发适用,部分技术或产品现已经在权属矿山得到应用。针对紫金山金铜矿,开发了一种替代水泥的新型胶凝材料,具有早期抗压强度大、沉缩率小的特点,远优于同等条件下水泥的性能。针对贵州紫金,在满足充填抗压强度的要求下,充填浓度可提高110%,水泥用量可减少40%。利用选矿尾矿开发研制了一种具有早强型高胶凝性水泥材料技术,与相同条件下的水泥充填强度相比,充填试块7d抗压强度提高123%~183%,28d抗压强度提高131%~243%。针对乌拉特后旗紫金矿业有限公司,开发了水泥替代材料,可使吨矿充填成本大幅降低,实现矿山选冶协同发展效应。
