ENRICHMENT FEATURES OF GALLIUM IN SHANXI'S BAUXITE DEPOSITS

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 Luliang 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.
