Eroding Confidence in Gully Location Risk Prediction in Mine Pit Rehabilitation

Land Degradation &Development, EarlyView.
ABSTRACT Understanding how rehabilitation measures, such as landform shaping, and surface finishes impact gully erosion risk could assist in designing less erosive rehabilitation. In this study we use high resolution digital elevation models of rehabilitated mine pits to explore risk factors for gully formation.

MAKING A SYNTHETIC ZEOLITE FROM A RESIDUE OF BAUXITE WASHING [PDF]

, 2020
A zeolite synthetic of NaA type is generally prepared by mixing the alumina and silicate-containing materials (alkali alumino hydro-silicates). The used raw materials include the amorphous solids such as metakaolin, siliceous earth, coal ash, kimberlite ...

Amending bauxite residue sands with residue fines to enhance growth potential [PDF]

, 2007
Long term success of rehabilitation on bauxite-processed residue storage areas is dependant on establishing a capping stratum which will satisfy water use and nutrient cycling requirements of the intended plant community.

Toward a Politics of Planetary Care: The Limits of More‐Than‐Human Approaches, Silenced Notes From Indigenous Forest Worlds in India

American Anthropologist, EarlyView.
ABSTRACT In response to the planetary climate crisis, influential scholarship has directed us to decenter the human, recognize nonhuman agency, and imagine more‐than‐human futures. But what might this leave out? Drawing on Indigenous forest worlds in India and the incarcerated intellectual‐activists who struggled alongside them, this article develops a

Hydrogen in Treatment of Bauxite Residues

Metallurgical and Materials Data
This study explores pyrometallurgical and hydrometallurgical methods for decarbonizing and recovering valuable metals from bauxite residue, with direct hydrogen reduction in a rotary kiln without smelting and dissolution of solid residues under high pressure in an autoclave.

Sustainable Indian alumina refineries: beneficiation and reuse of bauxite residue

, 2015
Alumina is produced by refining bauxite, which is stripped from open cut mines; aluminium, one of the world’s most important lightweight metals used in packaging, transportation and construction, is in turn produced by smelting alumina. About 259 million

Bauxite Residue: A viable filler for asphalt mix

Građevinar, 2022
Bauxite residue or red mud is used as surrogate filler for stone dust in asphalt concrete mixes. Asphalt mixes with both fillers were designed and strength, volumetric properties, and performance against various distresses (rutting, cracking, long-term ...

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 ...
