摘要
采集某砂岩型铀矿床卷头和翼部矿体矿石样品,进行粒度分布、物理性能参数及浸出性能对比试验。结果表明:翼部样品-0.08mm粒级碎屑质量分数比卷头样品高;翼部矿样较卷头矿样更致密,孔隙率更小,矿石含水更少;卷头矿心的渗透性较翼部矿心的好;2种样品化学组成相似,卷头样品氧化程度高,六价铀质量分数达62.1%,较翼部样品更容易浸出。
Ore samples were taken from the roll-type and wing ore bodies in a sandstone-type uranium deposit.And the contrastive experiments,for example,the size distribution experiments,physical parameters and leaching experiments between them were carried out.The results show that the mass fraction of-0.08mm ores of the wing sample is higher than that of roll-type sample.The wing sample is more compact,less poriferous and watery than the roll-type sample.The permeability of the roll-type sample is better than that of the wing sample.Two samples'chemical composition is similar except the roll-type sample has a high degree of oxidation and its U6+content is 62.1%.So the rolltype sample is easier to leach.
