15-04-2019· 1. Introduction. Bauxite manufacturing by the Bayer process in alumina production is associated with a by-product, bauxite residue (BR), traditionally termed “red mud” (Xue et al., 2016, Xu et al., 2018).In turn, BR has raised environmental concern in areas affected by plant effluents as related to its recognized toxicity since early studies (Trieff et al., 1995, His et al., 1996, Dauvin ...
The processes required to refine alumina from bauxite ore and to smelt aluminium from alumina require significant amounts of energy and depending on the energy source, significant emissions invariably result. Our focus and importantly, that of operating partner Alcoa, is on decreasing GHG intensity via:
According to Mr. Lyew-You, dust nuisance was the main complaint from persons living in bauxite communities, but through a Memorandum of Understanding (MOU) with the National Environment and Planning Agency (NEPA) in the late 1990s, in which the Institute agreed to monitor the bauxite companies on behalf of the environmental agency, emissions have been reduced by an average of …
Other air emissions could include NOx, SO2, and other products of combustion from the bauxite dryers. Ore washing and beneficiation may result in process waste waters containing suspended solids. Run-off from precipitation may also contain suspended solids. At the alumina plant, air emissions can include: bauxite dust from handling and

08-05-2014· The bauxite ore, Bayer process materials before precipitation, mud residue, and sand residue are therefore of radiological interest, whereas the alumina product is not.8 Positional and personal monitoring data from bauxite mines and alumina refineries in Western Australia have been used to assess the above-background annual doses for the workforce across a range of jobs.
that one steel plant such as the Usiminas plant, with an annual production of 4.5 million tons of steel (almost 20 per cent of Brazilian steel production), emits about 3,000 tons per year. In aluminium fabrication, finally, emissions of gases and particles from smelting and re-heating furnaces pose the largest problems.
Emissions from Aluminum Production Primary aluminum production involves refining alumina from bauxite ore, then smelting it to extract aluminum. Smelting is through the Hall-Héroult electrolysis process, which involves running large inputs of electricity through dissolved alumina via a carbon anode. Emissions result
Particulate emissions from reduction cells include alumina and carbon from anode dusting, and cryolite, aluminum fluoride, calcium fluoride, chiolite (Na 5Al 3F 14 ), and ferric oxide. Representative size distributions for fugitive emissions from PB and HSS plants, and for particulate emissions from HSS cells, are presented in Table 12.1-2.
Emissions Reduction – A New Challenge for Aluminium Smelters Paykan Safe, Matt Russell, Conor Grass Air emissions generated from the bauxite operations consist primarily of dust emissions generated by the Control of emissions generated from the lime kilns and calciners at the alumina plant

Pilot plant experiments verified a reduction of around 13 to 8-9 pH when carbonating the bauxite with flue gases containing around 8% SO 2. However, the pH of the red mud was found to rebound to an average of 10.5 after 150 days and remained constant thereafter.
Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process – with less than 1.5 kilograms of fuel oil (mainly in the form of diesel for haul trucks) and less than 5 kWh of electricity consumed per tonne of bauxite extracted.
To estimate emissions at the source, we need both spatial resolution that’s high enough to see plant operations and frequent observations to see how those measurements change over time.
