Bauxite residue is an important by-product of the alumina industry, and current management practices do not allow their full valorisation, especially with regard to the recovery of critical metals....
Bauxite is ground to less than 1.5 mm particle size at the refinery, using semi-autogenous grinding mills (SAG and/or Ball mills) to ensure sufficient solid-liquid contact during the digestion phase, which improves alumina extraction efficiency. A solution of hot
The spent Bauxite, commonly known as red mud, has been disclosed as having utility in the removal of phosphates from waste water. The red mud interacts with the phosphates and produces precipates which form a sludge which requires disposal. Thus, the aluminum from the Bauxite is removed for use in producing aluminum and the waste …

Foundry Sand - Material Description origin Foundry sand is a high-quality silica sand that is used to form molds for ferrous (iron and steel) and nonferrous (copper, aluminum, brass, etc.) metal castings. The raw sand is normally of higher quality than typical bank run or natural sands used in construction.
v The DrainPac ® filter removed total suspended solids with efficiencies ranging from 83% to 91% at flow rates of 20 to 200 gpm, with higher removal efficiencies at lower flow rates. The oil and grease removal efficiency of the DrainPac ® filter ranged from 40% to 82%.
bauxite processing residues are produced and these are deposited in residue disposal areas surrounding the refinery. At many refineries, the residues are separated into residue
• leachate collection, storage, treatment and disposal facilities • special waste management areas (e.g., tires, bulky wastes, asbestos) • planned total landfill footprint including buffer zones, landscaping, and site
insulation and spent bauxite, and other caustic materials. In the early 1980s, In the early 1980s, Kaiser submitted a Hazardous Waste Permit Application to the State of Louisiana
Effectiveness of a constructed wetland for treating alkaline bauxite residue leachate: a 1-year field study
In this work, we developed a simple, effective, low-cost and more environmentally friendly process (with low energy requirements and minimized effluent emissions) to recover molybdenum from an alkaline leaching solution of a spent hydrodesulphurisation catalyst, as a final product with high purity and in high yield.
Condensed light ends, spent filters and filter aids, and spent desiccant wastes from the production of chlorinated aliphatic hydrocarbons with carbon chain lengths from one through five by free radical catalyzed processes, with
