With the deposits in Chile its doubtful that deep mining can make money digging out Lithium

Well, with £1.7M raised by crowdfunding (according to the Daily Fail), if you're right there's going to be a lot of disappointment.

Crowdfunding is the 21st century's speculation.

Of purely historical interest, I have just uploaded John Arthur Phillips paper in the Philosophical Magazine 1873:

On The Composition and Origin of the Waters of a Salt Spring in Huel Seton Mine.

There is a later paper on other deep mine springs in Cornwall but I haven't managed to locate it yet.

I recall reading something about Lithium being present in minewater at South Crofty. Is the water treatment plant and dewatering going ahead? Last time I went past there was the steels of a new building going up. Would this treatment extract usable minerals? I would love a viable metal extraction industry to re-establish itself here.

as i understand this process? it seems that it would be used in conjunction with a geothermal heating project?
Fundamentally the operators pump down water, which heats up underground, then cones to the surface and the ionic solids are removed before it is passed into heat exchangers,
if I am correct in this then the Lithium amounts would be small but not insignificant!
they would have to chemically process it in order to produce an end product!
whether it is a financial goer i simply could not be sure!
the hot granite it has been suggested for years could be a reasonable call i would have thought, but why isn,t it an actual goer now?

Hi,
I see there was a reference to Huel Seton mine.
From my experience, in Cornwall a 'mine' is a 'wheal'.
What is the spelling of 'mine' in the Cornish language?

I am interested in Normandy iron mines, one of which is found at Breteuil sur Iton, formerly 'Bert Hoel'...
Could the latter be a celtic name ?

Any Welsh or Gaelic speakers out there ?

D.Send.

The word Wheal or sometimes spelled Huel means work or a place where work is carried out.
The Cornish name for a mine is a Bal hence Bal Maidens, the women that worked dressing ore at the Bal.
hope this helps.

You are confusing various unrelated issues.

The geothermal energy project, aka “hot rocks” dates from the 1970s and 1980s when exploratory drilling was carried out, principally at Rosemanowse quarry, to no ultimate outcome AFAIK. It has nothing to do with lithium.

There is nothing new about lithium salts being present in run-of-Mine water from deep Cornish mines. The problem is that the concentrations were never commercially viable, even as a secondary treatment to water which had been pumped as a cost of deep mining.

Various individuals close to the subject than myself have expressed their views of the current situation, I tend to the view that if it were worth doing, it would have been known and pursued long ago.

It’s a matter of historic fact that Cornish mining has a long, mostly peripheral tradition of dubious financial puffery, Mark Twain’s aphorism that “a western Mine, is a hole in the ground, owned by a liar” often held true West of the Tamar.

Lithium is a bit of a funding vehicle in the this country at the moment, whether it could ever be economical to extract here vs. the low cost producers in South America and elsewhere is another matter

My 2 pence...

My father has been involved in Lithium industry for over 30 years in senior roles with one of the lithium major company Lithco/FMC/now Livent and owns the largest proven lithium resource (joke!) in the UK - a lump of spodumene outside his caravan in N.Wales originally from Lithco’s ( now closed) Cherryville mine in North Carolina.
Lithium demand is generally measured in LCE’s (lithium carbonate equivalents) and in 2020 is expected to be around 300k mt/yr increasing to 1000k mt by 2025 based on electric vehicle sales. This growth and further growth past 2025 will make previously uneconomic resources viable, but not necessarily all of them. Cornish Lithium, despite press reports, has low quality resources from a global view and no proven technology to economically extract Lithium and then convert to a ‘battery quality’ lithium carbonate or hydroxide ( nice graphics do not prove anything). Invest in them with caution.
Most lithium today and in the future will come from brines in S.America and open cast spodumene mines in Australia, with others elsewhere under development. The only potential deep mine is in Zadar, Serbia where Rio Tinto have found new mineral zadarite which they hope will allow them to extract both borax and lithium but this is years (and multi million $ ) away.
Despite the almost daily announcements of new EV launches there is very little investment in developing new Lithium resources and as every EV needs lithium in it’s battery, then very soon battery demand will exceed lithium supply.

I have just uploaded a petrological study of lithium micas in South West England (mainly St Austell) written by my good friend Mike Henderson.

At great risk of nit-picking

the mineral is jadarite and the area is the Jadar valley, south west of the Cer Mountain in Serbia. They hope to extract lithium and boron, not borax (or even Borat)

Nit picking is fine buddy, I try to be as correct as I can. Thank you for the info/correction.
