The two filled tubes with the ponded mud are shown in Photos 5.

Other than a small leak at the contact between the two geotubes, the ponding of the muds was successful. The third tube was positioned on level ground. It was filled with medium runny but consistent thickness muds and was filled until the tube was taut. In all three cases, there was very little mud loss or seepage from the tubes. When stood on, some red water would squeeze out around the pressure area. Once filled taut, the entire bag would have small red water droplets form on the outside visible in Photo 5.

After 6 weeks the mud has not only firmed-up but had dried out significantly with wide and deep surface cracks as are evident in Photo 5.

Therefore, if pumping is to be used as the main method of moving the muds to regrade the pond, then the pump setup needs as a minimum the following:. It was also evident from the trials that the muds do not slump and flow readily. It will therefore be necessary to have an amphibious excavator to loosen up the muds in the area around the pump head.

This weakened and more liquid mud would also aid the movement of the pump pontoon. To also limit the amount of movement the pontoon will need to do, the amphibious excavator could also move muds towards the pump location.

A target period of 1 year however seems reasonable. However, prior to this, equipment will need to be procured and imported into Jamaica. The 6 and 10 inch Excavator Dredge Pump Attachments are also being considered as an option for higher GMP and a more aggressive completion timeline.

A preliminary programme is as follows:. Dec — March : Procure Pump and Amphibious excavator. Get pontoon fabricated in Jamaica April — May : Import plant and establish on-site June — June : Mud pumping and bulk earthworks July — July : surface stabilisation and start vegetation. It was also common for companies to dump the tailings into rivers and seas through pipelines. Several governments around the world made it illegal for the companies to dump the red mud in the seas which stopped the practice.

Companies were forced to adopt other methods of storage such as dry stacking. The red mud is then deposited in a way that it can dry. Red mud has a wide range of uses such as the production of cement and road construction. In the case of mud, it's best to let it dry out completely before attempting to clean it. The standard procedure for removing mud stains applies to washable fabrics only. If you have mud on dry-clean-only clothes, take them to a dry cleaner , or use a home dry cleaning kit , following the manufacturer's directions.

If the mud stain is on a leather garment , washing isn't an option. Instead, gently wipe off as much of the mud as possible with a damp towel, if the mud is still wet. Then, buff the leather with a dry cloth. If the mud has dried on the leather, use a soft-bristled toothbrush to rub off as much of the soil as you can, then rub the leather with a damp towel. Aluminum mining leaves behind a staggering million metric tons per year of the salty, highly alkaline, heavy-metal-laden material, according to the International Aluminium Institute , a London-based trade organization.

The aluminum industry has long tried to find ways to recycle the environmentally problematic red mud. But so far there have been few safe and economical large-scale applications. The deciding factors on implementation are cost and safety.

He calls the sulfidized red mud Azorb. In the Bayer process, strip-mined bauxite is treated with hot caustic soda sodium hydroxide , which selectively dissolves aluminum from an array of other mineralized metals. The end product is alumina, Al 2 O 3 , which is the feedstock for producing aluminum metal. But for every ton of alumina extracted, more than a ton of red mud is produced. Bauxite processors recycle the caustic soda and pump the residual red sludge into huge settling ponds.

When as much water is removed as possible, the material can be chemically treated to lower the pH and planted over with vegetation.

A flash flood of red sludge gushed through several small towns, killing 10 people by drowning and injuring more than others by burning their skin and irritating their eyes and lungs. Australia-based industrial waste management firm Virotec has developed a process to neutralize red mud with copious amounts of seawater or brine.

The resulting material is generally used to remediate mining sites, but it is also used as filler to make bricks and as a sorbent to trap metals and phosphorus in wastewater. Aluminum producer Alcoa has a process to carbonate red mud using CO 2 from industrial gas streams. Others have developed processes to recover iron and rare-earth metals from red mud.

Once aluminum is extracted from bauxite, the remains are a porous matrix of metals—a mineral skeleton, Iannicelli explains. As much as half of red mud is iron oxide, from which it gets its rusty color. Other major components include aluminum, silicon, titanium, calcium, and sodium oxides.

The material includes trace amounts of other metals, including radioactive uranium. With a high surface area, red mud is a natural sorbent capable of grabbing heavy metals and organic contaminants and sequestering them.

But red mud can also leach toxic heavy metals, which is an environmental concern. In the sulfidation reaction, sulfur atoms bind to vacant spots on metals throughout the skeletal network, locking the metals into place and preventing them from leaching. Sulfidation also tunes the red mud so that it has significantly higher sorbent capacity than untreated red mud, Iannicelli says.

The sulfidized red mud is not as efficient at removing arsenic, manganese, and strontium as red mud itself, Iannicelli says. But he suggests mixtures of red mud and sulfidized red mud might be an option for some applications. Once used, the material would be placed in a landfill. Hargreaves and his colleagues have been treating red mud with methane , a readily available by-product of oil refining and landfills.

Red mud catalytically decomposes methane to form hydrogen and an iron-carbon composite. The Glasgow researchers think the inexpensive magnetic composite material could be used to remove impurities such as arsenic and chromate from drinking water in developing countries. Iannicelli has also tested Azorb to clean up water discolored with natural dissolved organic compounds, such as tannins and lignin.

This is a problem encountered when the effluent of pulp and paper mills is discharged into rivers. With that in mind, Iannicelli has shown that Azorb readily traps and removes discolored compounds from Okefenokee Swamp water. Iannicelli also has been working with Altamaha Riverkeeper , a nonprofit environmental stewardship organization that is concerned with discolored water in the Altamaha River, which drains central Georgia.

9 thoughts on “Red Mud

  1. Red mud is a product of the Bayer process during the production of alumina (Hairi et al., ). As the temperature and pressure increases, the solubility of red mud decreases with sodium hydroxide (Nie et al., ). Its composition depends upon its parent material from which it is produced (Liu and Wu, ).
  2. Aug 20,  · One idea is to harness red mud, which is typically 40% to 70% iron oxide, to make iron-rich cements. The world uses more than 4 billion tons of .
  3. Red mud, also commonly called bauxite residue, is a waste product left over from the Bayer process, in which alumina is extracted from bauxite ore. Produced in mass quantities (estimates hover around tons of red mud per ton of alumina produced), red mud has become an increasingly debated topic as of late, both for the problems it presents and for the problems it could potentially solve; concern over the .
  4. With a high surface area, red mud is a natural sorbent capable of grabbing heavy metals and organic contaminants and sequestering them. But red mud can also leach toxic heavy metals, which is an environmental concern. Iannicelli’s sulfidation process involves treating red mud with sulfur compounds under ambient conditions or with mild heating.
  5. Nov 15,  · A waste by product of the Bayer process for producing al oxide from the bauxite ore, red mud contains toxic heavy metals and its high alkalinity makes it extremely corrosive and damaging to soil and life forms, presenting a massive problem for disposal.
  6. May 02,  · Red Mud is produced during the Bayer process for alumina production. It is the insoluble product after bauxite digestion with sodium hydroxide at elevated temperature and pressure. It is a mixture of compounds originally present in the parent mineral, bauxite, and of compounds formed or introduced during the Bayer cycle.
