Bauxite mineral is used directly, to remove phosphates from water, in a high efficiency, highly economical system. The process of the invention involves the step of contacting the waste water stream with Bauxite for a time sufficient to lower the phosphate concentration to a predetermined lower level.
Wastewater treatment demands as much attention, and the need for integrated solutions, as other processes within your operation. If you think about it, there are not many other processes that have so much variability in the input, yet a consistent, high quality output is required.
Wastewater from Mining. The only ore beneficiation operations performed at bauxite mines are crushing and grinding. Water used for dust suppression, water drained from the mine, and surface runoff generate a small volume of wastewater. This water is neutralized by lime and then discharged into nearby streams. Refinery "Muds" from Processing
The Bayer Process. The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste (red muds or sands) from the alumina.
Process Wastewater Distillation / Stripping. Many industrial and pharmaceutical processes generate wastewater with volatile contaminants that increase the chemical and biochemical oxygen demand (COD and BOD) to a point where discharging to municipal wastewater is very costly or not an option.
Mining Industry Wastewater Treatment Systems. Wastewater from extractive operations ( bauxite, coal, copper, gold, silver, diamonds, ... and metals from groundwater, and is upstream of a deionization process.
The waste water in the phosphate industry mainly comes from external drainage of mine and outdoor quarry, mineral processing wastewater, machine repair and auto repair water, life water, etc. Our company may take different measures according to the water …

OPTION E Option E for the bauxite refining subcategory consists of all control requirements of the existing BPT (no discharge of process wastewater pollutants, and discharge of net precipitation from process wastewater impoundments) plus pH adjustment and activated carbon adsorption treatment of the mud impoundment effluent.
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.
Through processing, bauxite residue has been shown to remove phosphorus compounds from waste water. Here, bauxite residue is modified and processed, and the structure-properties relationships are ...

According to the results above, it can be inferred that the oxidation process from Sâˆ' of solid phase in bauxite to ï€2 4SO of liquid phase is a chain reaction process [24,25]. There were some S-containing ions from Sâˆ' oxidation, such as S0, ï€23SO and ï€2 32OS [26].
The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production.

Red mud is a side-product of the Bayer process, the principal means of refining bauxite en route to alumina. The resulting alumina is the raw material for producing aluminium by the Hall–Héroult process. A typical bauxite plant produces one to two times as much red mud as alumina.

Phosphogypsum from phosphoric acid production. Slag from elemental phosphorous production. Gasifier ash from coal gasification. Process wastewater from coal gasification
On the basis of the evidence reviewed there are hazardous or potentially toxic substances in the wastes discharged from bauxite refineries. The use of waste water recycle systems, along with complete waste retention, permits the elimination of the discharge of all process waste water pollutants to receiving waters.
