RE: REPLACEABLE BATTERY CONTAINERS SAVE RECHARGING TIME17 Sep 2021 07:45
the ZESpacks approach has always to try and ride all the horses in the energy storage race by never tying their colours to the mast of a specific technology. This is, in my view, fence-sitting, and is not the way to really understand the devices that you are proposing to put onboard other peoples ships. It is also not the best way to produce a strong relationship with any suppliers you may have.
RE: Chinese import duty on Vanadium15 Sep 2021 17:58
Pdub - note even Delivery Duty Paid the buyer is likely to have paid or end up paying the import duties. As an exporter myself I am not going to cut my prices to a customer in La La land just because their government decides they don't like the stuff I make - instead the customer has to cover the charges. If they cannot be bothered to deal with their own customs authority and want me to do it then bill them later I am likely to not only add their import duties on top but also a processing and import handling fee just to teach them a lesson.
" Both lithium and tantalum already mined with globally significant resources within the same ore body (zero additional mining costs)
Lithium 450 kt of Li20 @ 0.63% grade Lithium market continues to be buoyed by the Li-battery market
Tantalum 6,091t of tantalum Every 20 tonnes of tin concentrate = one tonne of tantalum concentrate Used in capacitors, tantalum chemicals, alloy additives,sputtering targets, mill products and cemented carbides
Plant design targets: Sn recoveries >60% at concentrate grades of 60% Sn Ta recoveries >15% at a concentrate grade of 22% Ta Li recoveries >28% at a concentrate grade of 4% Li2O "
To understand these concentrate grades you have to appreciate the following
100% pure cassiterite (Sn2O5) is only 78.7% Sn by weight hence 60% Sn is >75% pure cassiterite
meanreverter - as everyone already here knows the Lithium (and the Tantalum) ARE going to be produced as a low cost by-product of the normal Tin production process, which by the way is already making profit. Hence the production costs of the lithium and the Tantalum are essentially zero.
