Filquip has done a number of Dense Phase Conveying Trials for Spodumene Ore (An ore of lithium).
When the product was first received it was quite wet in the sample bucket and this did not load or convey well, getting stuck. Once laid out in drying pans and dried out in the sun for 4 hours (5.3% loss of product weight or 5.3% of the original product weight was moisture driven off) then it conveyed very well through the dense phase conveyor.
The video shows how much the wet Spodumene binds to itself in the video of loading and conveying and then how easily it flows once dried out (but more dusty to handle once dried).
