The possibly slightly radioactive and highly corrosive material contains … The largest documented environmental release of this residue occurred in western Hungary in 2010 a er the failure of a retaining wall of a residue impoundment. There is growing interest in processing and utilizing the red mud by-product of the Bayer process for alumina extraction from bauxite. Many of the longer-term studies have aimed to model potential impacts on the soil–water environment, given that any longer-term impacts of the spill are most likely to affect these pathways, rather than the more short-lived air and water risks (Fig. 1). The dam failure and its impacts On October 4, 2010 at 12:30 p.m. the embankment of basin X of the red mud reservoir failed and released a mixture of 600-700 thousand cubic metres of red mud and water. There are still knowledge gaps regarding the effects of red mud on the soil microbial community. these focus on environmental impacts of the spill and cover the range of potential pathways and receptors for red mud (Fig. To prepare … Iron(III) oxide, the compound from which the red colour originates, … Environment Red Mud's Health Effects Toxic Spills: Hungarian accident may have fewer long-term health effects than initially feared by Sarah Everts February 3, 2011 ADVERTISEMENT. Red mud is composed of fair amounts of iron oxide, additional alumina, … Red mud is about one million times more alkaline than a neutral material. DOI: 10.1061/(ASCE)HZ.2153-5515.0000448. The red mud disaster of October 4, 2010, followed the collapse of the Chamber 10 dam in Ajka Alumina Refinery, Hungary.About 1.3 milliom m 3 sloppy slurry escaped and spread over a territory of some 10 km 2.. serious environmental impacts such as leeching into the water table. These studies have provided insight into the main environmental concerns, as well as the effectiveness of remedial efforts that can inform future … The unique project to produce ‘red mud powder’ has been commissioned in a fully mechanised and automated plant. The methodology of the assessment includes several techniques. A review on the potential uses of red mud as amendment for pollution control in environmental media. "WWF is fearful of the long term environmental impacts following the breach of the residue reservoir of the Ajkai Aluminia Refinery about 160 kilometres south west of Budapest. Journal of Hazardous, Toxic, and Radioactive Waste 2019, 23 (4) , 04019012. Red mud is a waste product from the Alumina industry and it creates a lot of health hazards to the ecology, if it is left disposed without necessary precautions, hence safe disposal practices and reuse of the product are one of the solutions. Light Metals (Warrendale, PA, United States) (1993), 41-4. Neutralization of red mud will help to reduce the environmental impact caused due to storage activities of the residue and will also open opportunities for the reuse of the residue which till now has been prevented because of the high pH. Performance of Lime Stabilization on Extremely Alkaline Red Mud Waste under Acidic Environment. Mining pits are often interspersed within small rural communities, therefore … Chin J Process Eng 9(1):459–464, in Chinese Google Scholar National Bureau of Statistics of the People’s Republic of China, 2014. Reports of the utilization of the red mud for the treatment of natural, industrial and domestic waste water are available in literature. Red mud is a by-product of mining bauxite, the raw material used for producing aluminium. During such activities one should be careful about the adverse environmental impacts. Mehwish Taneez, Charlotte Hurel. In India, major producer Vedanta Aluminium Ltd has commissioned a red mud powder processing unit at its Lanjigarh refinery in Odisha, probably the first of its kind in the alumina industry addressing major environmental hazards. The conventional method of disposal of red mud in ponds has often adverse environmental impacts as during monsoons, the waste may be carried by run-off to the surface water courses and as a result of leaching may cause contamination of ground water.
