Abstract

Abstract: The chemical composition， mineral composition， dissemination characteristics and ooidal characterization of the oolitic hematite ore were detailedly investigated through optical microscope， electron probe， XRD， MLA automatic detection and chemical analysis. The results showed that iron mainly occurs in the form of hematite and limonite，and the primary gangue minerals are quartz， chamosite and collophanite. Mineral composition of the ore is complex， and hematite is usually wrapped with annular and layer upon layer by quartz， chamosite， collophanite and clay minerals to form ooids. Ooids in the ore can be divided into ironrich ooid and ironpoor ooid， which are mostly distributed in the size range of 01～05mm. The results may provide the basis for the rational exploitation for the iron ore resource.

Key words: oolitic hematite, mineralogy, mineral composition, dissemination characteristics, ooidal characterization
