Upgrading Low-Grade Iron Ore through Gangue Removal by ...

It is therefore essential to develop a technology for an upgrading method for low-grade iron ore, which can be achieved by lowering the gangue content and raising the Fe content, for the sustainable development of the iron and steel industry, and the method has been sought after.

Upgrading of low-grade gold ore samples for improved particle ...

Upgrading is critical to increase the statistical significant number of Au particles found by SEM/EDX analysis. This is a challenge in Au mineralogical analysis since direct analysis of low grade Au samples using SEM/EDX could

Upgrading of Low-Grade Manganese Ore by Selective ...

The utilization of low-grade manganese ores has become necessary due to the intensive mining of high-grade ores for a long time. In this study, calcined ferruginous low-grade manganese ore was selectively reduced by CO, which converted hematite to magnetite, while manganese oxide was reduced to MnO. The iron-rich component was then separated by magnetic separation. The effects of the various ...

Beneficiation and upgrading of coarse sized low-grade bauxite ...

Beneficiation and upgrading of low-grade bauxite is important to the subsequent extraction of Aluminum metal using Bayer process. The mineralogical characterization of diaspore bauxite sample used in this work was performed using various analysis approaches. The results indi ed that the major components of sample were diaspore and kaolinite.

Low-Grade Coals: A Review of Some Prospective Upgrading ...

In general, the direct use of the low-grade coals results in higher costs of reducing emissions or in lower efficiency and, consequently, higher greenhouse gas emissions. In the present carbon-constrained environment, there is a need of upgrading these coals in terms of moisture, ash, and/or other trace elements.
