Analysis on metallogenic environment of the Fuxing bauxite in Zunyi area, northern Guizhou, China

[摘要] The ore-forming environment of Fuxing bauxite in the Zunyi area of northern Guizhou Province was analyzed by field geological survey, hand specimen observation and geochemical analysis. The results show that the sedimentary environment of Fuxing bauxite is a continental lake or marsh environment, and the sedimentary environment is reduced Environment, but the leaching process is an acidic oxidizing environment; Al has a good positive correlation with Ti, and Al has a negative correlation with Si and Fe; ore-bearing rock is formed in a strong acidic environment. Fe rapidly migrates to the bottom, but leaching when it is insufficient, Si does not have time to migrate, so that the Fe content in the ore is low but the ore grade is still low.
