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?
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.
