Physical Properties of Goethite Ore–Carbon Composite …
The rise in demand for iron- and steel-based products globally has resulted in the depletion of high-grade iron ores, high energy consumption, and CO2 emissions. The world is rich in low-grade ores that have not been exploited, and this study aims to develop a feed for cast iron production, goethite ore–carbon composite pellets. A pelletizing disc was used to make the …
