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。
Gallium (Ga) is a rare earth element that is widely enriched in bauxite. Shanxi bauxite is abundant and widely distributed. Selected Shangqiutou bauxite area of Qinyuan County of Shanxi Province, stone wall bauxite area of Yuanping City, Huilonglong bauxite mining area and Pangjiazhuang bauxite mining area of Luliang City, and aluminum The rock series as the research object, the content of elemental Ga in the bauxite and clay rock in the aluminiferous series has been systematically tested, and its enrichment characteristics and regularities have been determined. The content of elemental Ga in the five major mines is not high in the bauxite. Only in the stone wall mining area reaches the target of industrial recycling, the elemental Ga content gradually increases from Jinnan to northern Shanxi. However, the Ga content in the clay minerals in the five mines is generally high, both of which meet the industrial recovery requirements. The content of Ga in the clay rock has no obvious change in space.
