The English voice makes it easier to concentrate on the chemistry being discussed, but the soundtrack needs to be more carefully edited. At 4:00, a crucial phrase is omitted: "Afterwards, it can be calcine to obtain alumina."

Could not the red mud be processed in a blast furnace like regular iron ore to produce the steel? This is already using carbothermic reduction of the iron. Perhaps the other contaminants prevent it from being useful raw material?

It's interesting to learn how so many useful elements and materials (i.e. iron oxide, TiO2, SiO2 and especially Sc2O3) can be extracted from Alumina processing waste which was once discarded as useless (and toxic) red sludge. I'm just amazed no one else in that industry ever tried that before! And, I also agree with other comments about Thoisoi using his original Estonian-accernrted English voice again here as well!

The experiment is fine, but one major thing what you also highlighted regarding the disaster... The red mud should be dry. This is main challenge in industrial size, this is partly the reason why the store it... To make it dry.

The voice being used to narrate isn't bad, and does a good job, but definitely love hearing YOUR voice.

[@Dingomush]

I don’t see a good way of scaling up the process for the recovery of iron that would leave it cheap enough to compete against the influx of cheap metal in the market, or against the cost of mining raw material. Now, if you treated it like sulphur in the refining industry, where they incur the cost of extra steps just so someone else can carry away their waste product at a reduced price so they don’t have to deal with it, then it might work. It just lowers your profit on the expensive products that you extract downstream….

[@limbicsys7]

[@chrismpbuchholz]

I LOVE YOUR REAL VOICE AND ACCENT!! PLEASE BRING BACK THE ORIGINAL!! 🙂

[@agranero6]

I thought the Hall-Héroult process used bauxite directly mixed with criolite (to lower fusion point). But it seem it requires alumina. The first part of the process you describe is the preprocessing with NaO2. Extracting aluminium from Al204 (alumina ) is an electrolytic process and very energy intensive. The way you describe makes it seem that is just to use high temperature (calcine). It is not: the electrolytic method produces high purity aluminium directly. Trying to use heat directly would require far higher temperatures and contaminate the aluminum. A similar accident happened in Brazil but it was the red mud from iron production that is toxic but not corrosive. It destroyed an entire city and killed lots of people, not because of the toxicity that is lower, but because the huge size of the lake when the dam broke. The dams with red mud from alumina remain here waiting.

Electrowinning is often used on the molten aluminium salt. I wonder if reduction of the other metals can be achieved similarly.

This is a very interesting video. But I missed the part where it explains how you get Iron, Titanium and Scandium from this red sludge in a practicaal, efficient and enviornmentally friendly way. Because the heat processes and chemicals it has to go through to get there seem like it costs about 1000 as much to extract these elements as what they are actually worth.

[@Drachenfang]

I'm wondering if, rather than immersion in liquid nitrogen for the initial tablet treatment, you could just allow it to air cool in an argon atmosphere. I also wonder if rather than a carbon mix with the red sludge tablets you could use silicon which I imagine might precipitate out more easily as silicon dioxide later. Perhaps computer chip makers could be partnered with to utilize cast off silicon from their manufacturing process? Just speculative thinking. I am hardly a materials scientist or chemical engineer.

Similar environmental disasters happened in two cities in Brazil, in 2015 and again in 2018 (Mariana and Brumadinho, respectively), due to iron ore mining. Researching, I found out that something like that happened in Italy, in 1972! It's bound to happen again and again, because by-product production is expensive and the miners just don't care. It's much cheaper to bribe politicians than employ better methods (I know that, because I work at an environmental agency and decisions are made in "upper instances", against all our technical reports...)
