Advances in Understanding Environmental Risks of Red Mud After the Ajka Spill, Hungary [PDF]

, 2016
In the 5 years since the 2010 Ajka red mud spill (Hungary), there have been 46 scientific studies assessing the key risks and impacts associated with the largest single release of bauxite-processing residue (red mud) to the environment.

Radiological assessment of the bauxite residue valorization chain [PDF]

Journal of Radioanalytical and Nuclear Chemistry, 2019
The behavior of radionuclides in the bauxite residue valorization chain has been analyzed, and accumulation ratios have been measured for secondary residues produced after recovery of valuable metals. Key analysis outcomes are valid specifically for the processes and raw materials in use at the Aluminium of Greece plant and are as follows: the ...

Microbially-driven strategies for bioremediation of bauxite residue [PDF]

Journal of Hazardous Materials, 2015
Globally, 3 Gt of bauxite residue is currently in storage, with an additional 120 Mt generated every year. Bauxite residue is an alkaline, saline, sodic, massive, and fine grained material with little organic carbon or plant nutrients. To date, remediation of bauxite residue has focused on the use of chemical and physical amendments to address high pH,
