That is an interesting product.
Yeah, HF preferentially removes the areas of the sand grains with the most impurities.
It also increases the surface area and 'activates' the silica to some extent.
It is used as a pretreatment in making catalysts

Awesome. Well that rust stain remover hopefully would suffice, if not, I'm not going to risk dealing with any other higher concentration of HF (I am still a chemical newbie, after all, and this is just sand, lol).

Will update you after I do the HNO3[:HCl] leaches. Thanks for the replies everybody! These forums are awesome :-)
