Bauxite residue (red mud) increases phosphorus retention ...

The Peel-Harvey estuary on the Swan Coastal Plain, Western Australia has become eutrophic partly because of the leaching of fertiliser phosphorus from sandy soils. The acid, coarse textured sandy soils are predominantly quartz, have a low iron and aluminium content and do not retain phosphorus. Red mud, derived from bauxite, is a by-product of the alumina industry and has the ability to retain ...

Low P hematite-rich Jamaican bauxite supplies are limited and high P goethite-rich ores will eventually replace them. • Goethite-rich bauxites may have 10–100 times higher P concentrations than hematite-rich ores. • Soluble PO 4 3− from goethitic bauxites was 5–21,000 mg/L and hematite-rich ores 52–319 mg/L. •
