What is this in my alcohol extract?

[abekl]

When I make RSO, I do so using 99% Iso alcohol.

When I do th4e first rough filtering of the oil/alcohol mixture, I'm left with a sandy appearing stuff at the bottom of the unfiltered alcohol.

What is this sandlike substance? and should I be doing something with it?

Thanks
