Red Mud

The primary source of alumina, and, after further processing, aluminum, is the ore bauxite*. The main technique used to refine bauxite into alumina is known as the Bayer process, developed by Carl Josef Bayer, from Austria-Hungary, in 1888.

While the Bayer process is crucial in the aluminum supply chain today, it also generates what is known as red mud, or bauxite reside, a substance with a high pH, toxic heavy metals, and, often, radioactive elements or compounds. The disposal of this industrial waste product is therefore of high environmental concern. Many safety incidents have been documented regarding the storage and disposal of red mud, the worst of which is often cited as the Ajka alumina plant accident in western Hungary in 2010. The red mud in this incident was stored as liquid waste in reservoirs; when a dam collapsed in one of the reservoirs, the waste flooded nearby areas, including towns, killing several and injuring scores more.

Attempts have been made over the decades to safely dispose of or use the red mud, the former including various neutralization methods and the latter including raw materials recovery (primarily iron, but also titanium and rare earth elements), but large scale processing has yet to be proven economically viable. Several million tons are estimated to be used annually, but this number must be contrasted with the fact that the global stock of red mud, as of 2020, was known to be greater than 5 billion tons.

This is horrifying but not at all shocking. Another reminder that electric vehicles are not all that eco-friendly and that their production depends on environmental racism.

"CANADIANS BEAT JUNGLE, SNAKES, TO BUILD WAR-VITAL RAILROAD," Porcupine Advance (Timmins). August 26, 1943. Section 1, page 2. --- Canada's Plane Programme force opening of new Bauxite Mines in British Guiana - Roadbed Kept Disappearing into Swamp, Manager says - 40-mile Road took Year to Complete ---- Montreal, Aug. 24. - Canadian-born engineers have just completed constructing a railroad through forty miles of steaming Jungle in British Guiann, and "they had first to kick the snakes out of the way and then lay the roadbed over and over again he cause the gravel kept disappearing into the swamp," says F. L. Parsons, general manager of the Demarara Bauxite Company, Ltd., who oversaw the job.

Aluminum plants in Canada, turning out the metal which keeps the United Nations flying, forced construction of the new railroad, says Mr. Parsons, now visiting this city. "It taken four tons of bauxite to make one ton of aluminum and your Canadian plants have been eating up the mineral at such a pace that down in South America we have had to open new bauxite mines. We now have to strip from the mine site an overburden of earth up to 100 feet thick.

"It took a year to build those forty miles of road. It runs from Mackenzie, where we crush, wash and dry the bauxite, to a spot in the jungle called Ituni. We had unskilled labor. And we had to deal with the mud, the snakes, and sometimes an ocelot, which is a South American tiger.

"This job has added to the reputation of Canadians, which is already high in South America. They like us down there because we treat the people well. For instance, our colored boys like to travel by train so we give them free rides on the railroad in our Pullmans - old freight cars with the sides out and benches in. And we take good care of our white people, of course. Recently we found it necessary to build a swimming pool for them as they cannot bathe in the river with safety because of a freshwater shark called the piranha, a vicious little brute about eighteen inches long, nearly all mouth and three rows of teeth. It bites off fingers and toes. In gangs this fish even brings down cows drinking in the river. It's a curse.

"Now we're ready to operate our new road, which the people of British Guiana foresee will ultimately lead to opening up back country full of riches. I hope Canada will follow up the good impression her engineers and other technicians have been making down there. Recently, the Daily Chronicle of Georgetown, said: "Taking a retrospective glance, one is bound to say that the history of industrial, economic and social development in this country in the past decade cannot the written without allotting priority of place to the Canadians, our greatest Empire cousins in the Western Hemisphere.

"The job Canadians are doing to the south can, I believe, be built into a lot of good post-war business."

A black marble composition book….reminds me of Watooka Day School. Students at Watooka Day used these books instead of the standard Guyanese exercise book. There were other special things.

Watooka Day was created by the bauxite company (called Guymine when I was there; called Demba originally, which was owned by Alcan Aluminum). The Chinese took over bauxite mining operations in Linden. The company is called Bonsai Minerals Group Guyana Inc.

Refractory and Aluminium Usage Likely to Fuel Growth in Bauxite Market

Refractory, a material used inside a furnace for providing protection from high temperature and corrosion, is among the market’s most important application segments. Refractories are used in various industries including petrochemicals, cement, glass, steel, and cement. Bauxite due to its high melting point is always in great demand as the raw material for the manufacture of refractory products. The roofs of electric arc steel marking furnaces and blast furnaces are lined using bricks made of refractory grade bauxite. This has surged the demand for refractory and aluminium, which in a way, created notable demand for bauxite at global level. In coming years, rapidly increasing industrialization and demand for aluminium is anticipated to propel growth across the global bauxite market. 

Extensive Application in Cement to Aid Global Market Bauxite Growth

Another application segment predicted to experience growth in the forecasted period is Cement. The bauxite residue is used as an additive in the manufacturing of Poland cement clinkers. Russia, India, China, Moldova, Ukraine, India, Georgia, and Greece are the countries who currently use bauxite residue in their cement sectors. The manufacturers are collaborating with the cement industry to produce cement using bauxite residues and limestone. The cement thus made is rich in alumina content, possesses great strength and settles down quickly. Such an extensive application of bauxite in producing cement is projected to put forth a substantial business opportunity. In coming years, the key players are likely to roll out new products and form strategic alliances to sustain competitive advantage. 

Bauxite Market in North America to Experience Fastest Growth in Forecast Period

Metallurgist explains the surprising properties of aluminum

Despite being the most abundant metal on Earth, constituting over 8% of the Earth's core mass, aluminum was only discovered in the 1820s, by Danish physicist Hans Christian Ørsted. This is partly explained because pure aluminum doesn't exist in nature as it binds easily with other elements like oxygen.

Our main source of aluminum is the sedimentary rock, bauxite. As Van der Eijk explains, "It takes about four kilos of bauxite to produce one kilo of aluminum metal. After mining the bauxite ore, aluminum oxide is extracted. Then, the aluminum and oxygen are separated by an electric current passed through a molten solution of alumina and the mineral cryolite, which dissolves the oxide minerals."

It wasn't until towards the end of the 19th century that aluminum was produced at an industrial scale, and its properties proved invaluable. It is lightweight—about a third the weight of steel. "It is also soft and malleable, so can easily be cast or formed into many different products," adds Van der Eijk.
