LITHIUM , assez de ressources pour tous les véhicules électriques ?

On n'est pas prêt de manquer de Lithium! C'est juste un problème technique de membrane pour filtrer l'eau de mer.



Il y a 16 000 fois plus de lithium dans les océans que dans les réserves terrestres connues. (bien noter billion vs million tons)

Il faut juste mettre au point une membrane efficace qui ne consomme pas trop d'énergie.



On trouvera un jour cette fameuse membrane qui ne laisse passer que les ions Lithium (on sait le faire pour d'autres éléments chimiques).

L'électronique au SiC, ça existe pour l’électronique de puissance. Par exemple chez Tesla, les convertisseurs DC-DC sont en SiC. Le rendement est meilleur.
Sinon, la technique actuelle majoritaire c'est du Silicium, et ça on n'est pas prêt d'en manquer (à condition de payer plus cher pour exploiter les sables des déserts).
Il y a aussi de l'électronique sur diamant synthétique, mais ça reste assez confidentiel.

Il y a un projet de mine de Lithium en Allemagne. A 35 km de Dresde.

Zinnwald

Bacanora plans to sell 50% stake in German lithium project to Erris

1 October 2020

Lithium development and exploration company Bacanora Lithium has announced its plans to divest its 50% stake in Germany’s Zinnwald lithium project in exchange for a majority stake in Erris Resources.

.......
The Zinnwald project is Deutsche Lithium’s main asset. It is located in southeast Germany, about 35km from Dresden.

J'avais jamais entendu parler de ça, il y a des ressources en Lithium de spodumene en Caroline du Nord.
Piedmont Lithium signe un accord commercial de 5 ans avec Tesla pour leur fournir du concentré de Lithium de spodumene.

Piedmont Lithium strikes sales deal with Tesla

Sept 28, 2020

Piedmont Lithium Limited has struck a sales agreement with Tesla to supply spodumene concentrate (SC6) from Piedmont’s North Carolina deposit.

The Agreement is for an initial five-year term on a fixed-price binding purchase commitment from the delivery of first product, and may be extended by mutual agreement for a second five-year term, and follows the electric vehicle maker's announcement last week that it plans to mine its own lithium for EV batteries as it seeks to ramp up production at its Nevada Gigafactory.

The deal covers a fixed commitment for approximately one-third of Piedmont’s planned SC6 production of 160,000 tonnes per annum for the initial term as well as an additional quantity to be delivered at Tesla’s option. SC6 sales are expected to generate between 10-20 percent of Piedmont’s total revenues from its proposed integrated mine-to-hydroxide project for the term. The Agreement is conditional upon Tesla and Piedmont agreeing to a start date for spodumene concentrate deliveries between July 2022 and July 2023 based on the development schedules of both parties.

Keith D. Phillips, President and Chief Executive Officer, commented: “We are excited to be working with Tesla, which represents the start of the first US domestic lithium supply chain and a disruption to the current value chain. The Agreement highlights the strategic importance of Piedmont’s unique American spodumene deposit and confirms the trend toward spodumene as the preferred feedstock for the lithium hydroxide required in high-nickel batteries.

Piedmont plans to extract lithium from mineral deposits in Gaston County, 25 miles west of Charlotte, in what geologists call the 'Carolina Tin-Spodumene Belt'.

“We will now accelerate our mine/concentrator development to support Tesla’s plans, work to further expand our mineral resources, and potentially increase our planned annual spodumene concentrate production capacity. We will simultaneously be advancing our plans to produce lithium hydroxide in North Carolina, using a combination of internally produced spodumene concentrate as well as material sourced from other producers around the world.”

Piedmont confirms that all material assumptions underpinning the results of its previously announced integrated scoping study continue to apply and have not materially changed, including Benchmark Mineral Intelligence pricing and tonnes per annum assumptions.

Savannah’s Portugal lithium project moves to next permitting phase

Cecilia Jamasmie | November 26, 2020

Savannah Resources said on Thursday that, as part of the next stage in the environmental impact assessment (EIA) process for its Mina do Barroso lithium project in Portugal, it had submitted further and revised information to the country’s regulatory authority.

The additional submission comes in response to a request received from the Portuguese environmental watchdog, Agência Portuguesa do Ambiente (APA), the company said.

Savannah said the move underlined its commitment to developing and operating Mina do Barroso in a “low impact, responsible and sustainable” manner.

The multi-commodity developer, which is listed on AIM, the London Stock Exchange’s international market for smaller firms, said it expected to receive a “declaration of the conformity” from APA for Mina do Barroso’s EIA in the next 20 working days.

That declaration would be followed by a period of public consultation, during which the assessment would also be reviewed by APA’s evaluation committee.

Taking into account the Christmas holiday period, Savannah said that phase was expected to begin in early 2021.

Results from the public consultation and the evaluation committee’s review would then form the basis for the committee’s “final technical statement.”

Such document would allow APA to prepare the contents of the environmental impact declaration, and award such a declaration to the project.

That would complete the pre-phase stage of the application process, which would then move to the second stage, expected to take 60 working days, and subject to receipt of approval from the APA, would result in the project receiving its environmental title.

Europe’s first

Savannah acquired a 75% interest in Mina do Barroso in May 2017 and it has maintained a fast paced development approach since.

The project holds a resource estimate of 20 million tonnes of lithium with over 200,000 tonnes contained Li20. Additionally, metallurgical test-work results have produced a 6% Li20 low impurity concentrate, which according to Archer is “ideal” for the EV battery industry.

The company believes that Mina do Barroso will become Europe’s first significant producer of spodumene, a hard-rock form of lithium.

One hiccup is that based on experts’ estimations, it is 2.5 times more expensive to produce lithium extracted from Portugal’s granite rocks than from the brine fields of Chile, which hosts some of the planet’s largest known reserves of the white metal.

“Mina do Barroso is in the lower quartile of spodumene lithium costs internationally and is the best European analogue of the successful Australian producers,” chief executive David Archer told MINING.COM last year.

“Australia is now the dominant producer of lithium illustrating the superior competitive position of hard rock producers of lithium, which is preferred for producing lithium hydroxide and has cost advantages over brines,” he noted.

Mina do Barroso is set to initially produce 6% Li2O spodumene concentrates destined for China. The open-pit mine will also yield a feldspar and quartz co-product to be sold to ceramics industry customers locally and in neighboring Spain.

Portugal, already Europe’s top lithium producer, accounts for about 11% of the global market, but its output is entirely used to make ceramics and glassware. That’s why Europe relies on lithium imports from Latin America’s “Lithium Triangle,” as well from Australia and China.

Encore un nouveau projet de Lithium de Salar en Argentine, le Sal de Vida.

Galaxy Resources to raise $118m for Argentina lithium project

Cecilia Jamasmie | November 25, 2020

Australian lithium miner Galaxy Resources (ASX:GXY) said on Wednesday it planned to raise A$161 million (about $118m) to fund development of its projects in Argentina and Canada.

Most of the capital raised will be used to advance the first stage of development of the company’s Sal de Vida lithium brine project, in Argentina.

Front-end engineering and design for stage 1 of that project is slated for completion by first quarter next year, with first production expected in late 2022.

The funds will also be used to get the James Bay lithium pegmatite project in Canada construction-ready, Galaxy said.

The company is allowing shareholders to purchase one new share for every 14 existing shares held for A$1.70 each. The figure represents a 15% discount to Galaxy’s last trading price.
