curious_joy, the "worry" is...separating the nano tubes may not be that simple and they may never find a cost-effective way to do it. In the meantime, no sales to nano customers until they can determine the quality, cost, etc. of the separation process. To date, they have not indicated any progress in the separation studies.
Curious_joy, "a small percentage of the clay... after Natural Nano's separation process, are nanotubes, but the byproduct/rest can still be used in the ceramics industry".
I missed that good news ... would you please post a source confirming that? TIA.
