rd around driving value from red mud increases

Red mud is a byproduct of aluminum production, in which alumina is extracted from bauxite ore via the Bayer process. Unfortunately, for each ton of aluminum produced, around 1-2 tons of red mud are also produced, creating a massive amount of industrial waste to manage. This red mud, or bauxite residue, represents a significant challenge to the industry due to its highly caustic nature and the ... Jan 01, 2016 The micro-sized redmud particles have been modified to nano structured red mud using high energy ball milling. Composites were fabricated by stir casting and experiments were conducted under laboratory condition to assess the wear characteristics of Al-5 wt% red mud (micro-sized) and Al-5 wt% red mud (nano-structured) composites on pin-on-disc wear testing machine. The hardness of the ...

bottles. A mass of 2.0 g of red mud was added into bottles to construct the red mud supplemented reactors with 10 mL of sludge inoculums and 90 mL of substrate. The bottle without the addition of red mud was designated the control reactor. After bubbling the medium and headspace with N 2 gas for 15 min at a rate of 5 mL/min, Teon-coated red mud has been investigated for the removal of nutrients. According to Liu, et al. 12 and Huang, et al. 20, red mud has potential for phosphorus removal. However, there is no study on removal of nitrogen by using red mud. Thus the aim of this work was to use red mud as an absorbent to remove nitrogen and phosphorous from wastewater of
