Hematite Processing by Flotation
Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with “Sub-A” Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 and with a high recovery.

Hydrogen Reduction of Hematite Ore Fines to …
Surplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could simultaneously enrich CH 4 from COG and produce separated magnetite from low grade hematite. In this work, low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring apparatus, and a laboratory Davis magnetic …
EFFECTIVE PROCESSING OF LOW-GRADE IRON ORE THROUGH …
difficulty in processing and utilization of low-grade iron ores primarily stems from their mineralogical characteristics as well as the soft nature of some ores and their high silica content. Thus, beneficiating the low-grade iron ores to remove the gangue minerals and enhancing their grade is an attractive proposition today. Among the
