A settling basin, settling pond or decant pond is an earthen or concrete structure using sedimentation to remove settleable matter and turbidity from wastewater.The basins are used to control water pollution in diverse industries such as agriculture, aquaculture, and mining. Turbidity is an optical property of water caused by scattering of light by material suspended in that water.

Much of the bauxite residue goes to landfill, or left in vast settling ponds. Some success in recovering ferrous materials from residues has been achieved in China, particularly at plants in Southern China where the wastes can have an iron content of up to 42% that makes the recovery economically feasible.

Jamaican bauxite was not used during the war, but these three North American companies (Alcan, Kaiser and Reynolds) came to the island to survey, acquire reserve lands and set up operations. Reynolds began exporting bauxite from Ocho Rios in June 1952, and Kaiser followed a year later from Port Kaiser on the south coast.

The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.

Bauxite residue is a by-product of the Bayer Process. It is primarily composed of the insoluble fraction of the bauxite ore that remains after extraction of the aluminium-containing components. Iron oxides (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%) and undissolved alumina (0 – 20%) make up the residue, together with ...

It should be noted that the measuring point of the water turbidity is downstream of a settling pond where coagulation agents were added which caused the bulk solids to settle. Independent of the huge variability of the feed turbidity, the Pall hollow-fibre system showed a stable and reliable operation.

Resourcing of research and development projects. Bauxite mining consumes a relatively small amount of energy (and consequently has low greenhouse gas emissions) compared to alumina refining and aluminium smelting processes. Diesel fuel and fuel oil combustion provides the bulk (95%) of the energy required to extract and haul the mined ore.

Bauxite, the raw material of aluminum, has been one of the economically vital natural resources for Suriname. Mining operations started about a century ago, and subsequent development of a refinery industry and hydro-electric power made Suriname one of the foremost bauxite and alumina producers worldwide for a long period of time.
