赤泥中的三稀矿产资源综合评价--以桂西地区为例

Mineral resource synthesis evaluation of rare earth,rare metal and rare-scattered elememts from red mud——A case study from western Guangxi

对桂西不同铝业公司赤泥中三稀元素含量的分布特征及三稀资源状况的调查表明,赤泥中Ga、Sc、Zr、Hf、Nb、Ta和轻、重稀土元素的含量,与原矿相比均有不同程度的富集,与风化壳型矿床的相关工业指标相比,均达到了综合回收的要求。按照目前桂西各大铝业公司库存赤泥总量4 000万t计,可得轻稀土的资源量为3.21万t,重稀土资源量为1.49万t,镓资源量为2 494.8 t,钪也具有巨大的资源潜力。

According to the distribution and characteristics of the rare earth,rare metal and rare-scattered elements in red mud from different aluminum companies in western Guangxi,the content of Ga,Sc,Zr,Hf,Nb,Ta,and the light and heavy rare earth elements in red mud has different degrees of enrichment compared with the original ores. It reaches the requirement of comprehensive recovery according to the related industrial index of regolith type ore deposit. According to the amount of the current major aluminum companies＇ inventory,there are about 40 million tons red mud. It can get the light rare earth resources about 32 100 tons,heavy rare earth resources 14 900 tons and gallium 2 494. 8 tons from the red mud. The scandium in red mud also has a great resource potential.
