Processing of Banded Hematite Quartzite Ore for

This study investigates upgrading of low-grade banded hematite quartzite iron ore (Fe ~31%). Conventional beneficiation was found to be futile. The susceptibility of iron phases to microwave exposure and their selective absorption assists in the liberation of iron values. Microwave exposure of coarse particles at 540 W for 10 min yielded a concentrate with Fe 56.30% and recovery of 50.68%.

Hydrogen Reduction of Hematite Ore Fines to Magnetite

The conversion of Fe 2 O 3 in the hematite ore played an important role in the total iron recovery and grade of the concentrate. The grade of the concentrate decreased, whereas the total iron recovery increased with the increasing Fe 2 O 3 conversion. Surplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could ...

01/02/2021  The concentrate Fe recovery dropped sharply from 97.25% to 68.84% in the presence of nanobubbles and from 90.10% to 47.85% in the absence of nanobubbles with increasing the collector dosage from 0.10 to 1.0 kg/ton. The data indicates that both concentrate grade and recovery are strongly dependent on the dosage of anionic collector, which is consistent with known chemistry of hematite

Recovering fine gold from black sands is one of the most challenging aspects of gold mining. While we are all hoping to find that once-in-a-lifetime gold nugget, the vast majority of gold that we find as prospectors is very small in size, ranging from gold flakes down to dust so small that it is nearly invisible. Extremely fine particles of gold like this can be very difficult to separate from ...
