High Temperature Treatment of Selected Iron Rich Bauxite Ores to Produce Calcium Aluminate Slags

Materials Proceedings, 2021
The Pedersen process is a method to produce alumina from Al-containing sources, and it is a more material-efficient method than the current commercial Bayer process, since the formation of bauxite residue (red mud) is avoided, and the bauxite can be ...

Evolution of ecological indicators in the assessment of restoration of mining‐degraded riparian forests: a global bibliometric analysis (1990–2024)

Restoration Ecology, EarlyView.
Abstract Introduction The restoration of mining‐degraded riparian forests faces challenges due to structural, compositional, and functional impacts on these ecosystems. The demand for effective monitoring requires an understanding of how ecological indicators have been applied to assess post‐mining restoration success.
