[Edited my original comment to include processing plants].
There is a secondary stage of processing after extraction which is highly toxic, that is the polluting part. Have a look at the huge tailings dams they set up to hold the toxic waste. These things just kick the can down the road for future generations. They also probably leak into groundwater. Lucky you don't have to drink that water.
Non of the processing plants are in Africa. So I have no idea what you are talking about. There is like 1 lithium mine in Africa and I'm not even sure it produces lithium for batteries. As far as I now not a single lithium refinement facility is in Africa.
The waste majority of lithium comes from Australia, China or South America. If you look at industry statistics, 90% of lithium refinement is done in China.
Lithium refinement isn't actually that dirty or polluting. Please provide with evidence of what is so bad about it if you want to make that claim. Where in China can people not drink the water because of these plants?
I am seriously questioning where you get the data for any of the claims you make.
If you want to talk about Africa, the real issue is not lithium but rather cobalt from the Congo. And the issue there is not refining as this is done in China. The issue there is artisanal mines employing children.
For some sound figures, see the 25 years of lithium production graphic here [1] Australia is responsible for twice the seperated end product as Chile which itself produces twice that of China (2021).
Half of Australias 55.4 ktonnes of production (REO) comes from Mt Weld ( 240,000 tonnes per annum of ore to produce up to 66,000 tonnes per annum of concentrate containing 26,500 tonnes of REO ) [2].
Mt Weld Australia ships its concentrate to the world’s largest single rare earths processing plant in Malaysia[3].
These figures rather undercut the assertion that:
> If you look at industry statistics, 90% of lithium refinement is done in China.
Can you link to the "industry statistics" that you are quoting? Thankyou.
Its really hard to find stats for refinement. I thought I had seen 90%, but I do not remember where. Your [1] seems to suggest its only 60%. So I might have been wrong on that.
[ China ] also hosts 60% of the world’s lithium refining capacity for batteries.
AND states that :
Batteries == 74% of total lithium usage
So that's 60 % of 74 % of global refining capacity (I'll leave the math for you)
That's also a tad out of date as it fails to account for post 2020 refining plants and the coming changes as proposed plants (eg: Musk's super Texas plant) lay ground and get built to start production in (?) near future.
You need lithium refinement not just for batteries. You don't need lithium as poor for other applications, but its still has to be refined. So its more like 60% of all global lithium refinement.
China has less % of that in terms of battery materials production, as that is also very common in South Korea and Japan.
> and the coming changes as proposed plants
Yeah but its not only the rest of the world that has plans. Lithium refinement capacity in China is also growing.
Partly why Tesla is building the refinement plant is because of Chinas dominance.
