Most materials in Dune: Awakening are easy enough to find and harvest, not least because they respawn so frequently. However, spice sand is much more complicated as it requires a specific tool to harvest and is easy to miss if you don't know what you're looking for.
Sending you out into the worm-infested dunes, spice sand, and its less psychedelic counterpart, flour sand, can be dangerous to collect. I recommend you have a vehicle at the ready, like a sandbike, so you can grab what you need before zooming away.
