摘要:

镓(Ga)是一种稀散元素,在铝土矿中广泛富集;山西铝土矿储量丰富,分布广泛。选取了山西省沁源县上务头铝土矿区、原平市石墙铝土矿区、吕梁市回龙铝土矿区和庞家庄铝土矿区以及太原市阳曲铝土矿区中含铝岩系为研究对象,系统测试了含铝岩系内铝土矿与粘土岩中元素Ga的含量,并确定了其富集特征与规律。五大矿区中元素Ga在铝土矿中的含量不高,仅在石墙矿区达到工业回收利用指标,元素Ga的含量从晋南到晋北呈现逐渐增高的趋势。而五个矿区内粘土岩中Ga含量普遍较高,均达到了工业回收要求;粘土岩中元素Ga含量在空间上没有明显变化规律。

Abstract:

Gallium (Ga) as a dispersed element is widely distributed in bauxites. Shanxi province abounds in bauxite resources. This paper, based on Shangwutou bauxite in Qinyuan county, Shiqiang bauxite in Yuanping city, Huilong and Pangjiazhuang bauxites in Lüliang city and Yangqu bauxite in Taiyuan city, measures the Ga content in bauxites and in clay layers, and analyzes its enrichment features and rules. Ga is not high in bauxites, only can be recovered in Shiqiang bauxite, and shows a increasing trend northward. In clay layers, Ga is extensively high, all can be recovered, but no obvious spatial rules.

Key words: Shanxi, bauxite deposits, clay rock, Ga
