It probably depends on whether they are 2 dimensional disks or 3 dimensional cylindrical structures. I'd guess they have some 3 dimensional depth and will not go away unless you remove a lot of surface material. One way to check would be to quickly buff them on a diamond wheel, or even a piece of wet sandpaper. Once you remove a little of the surface you will know something about their depth and hardness.

We collect a lot of plant fossil material, and a couple little fish, in a soft stone [compressed volcanic ash] that looks a lot like yours. Most of our matrix rock is soft enough to cut with a carbide grit saw blade and some light enough to float. If you start grinding on it or throw it in a tumbler you will most likely ruin it really fast. That's a nice piece, my opinion, keep it as it is.

It looks pretty soft. Can you scratch it with a nail?
