Sep 16, 2019· Abstract. This study investigates the microwave carbothermal reduction of lowgrade banded hematite jasper iron ore (Fe ~ 37%). The susceptibility of iron phases to microwave exposure and their selective absorptions help in the liberation of iron values from impurities.
The liberation of hematite particles can be enhanced to about 82% by reducing the particle size to below 63 μm. The rejection of silica particles can be obtained by magnetic and flotation separation techniques. Overall, the BHQ ore can be enriched to % Fe at % iron recovery.

A flotation process has been developed to treat one such ore, namely banded hematite quartzite (BHQ) containing % Fe and % SiO 2, by using oleic acid, methyl isobutyl carbinol (MIBC), and sodium silicate as the collector, frother, and dispersant, respectively. The relative effects of these variables have been evaluated in half ...
Abstract. A novel approach for the complete utilization of a lowgrade banded hematite jasper ore assaying ~ 47% Fe has been taken in order to address the issue of rapid consumption of highgrade iron ores and the rising concerns of waste disposal.
Hematite and quartz present in banded iron ore are intimately associated with one another and require fine grinding for the liberation of mineral particles. The influence of the thickness of bands on the liberation and flotation response of banded hematite quartzite (BHQ) ore is investigated.

Jan 04, 2007 · Hematite and magnetite are the most prominent iron ores. Most of the highgrade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.
