Slates can be so different.
That looks like a flat slate that may contain some calcites.
I would check the porosity and see if a sealer is on the surface. If it is sealer residue polishing compound will remove it as Fred suggested.
You can refinish these using diamond impregnated pads as well as honing powder, resin pads.
Once you know the character of the stone you can treat it more effectively.

Here is a link to it on Amazon. I buy it at a local place. I think they also sell it at home depot. I have only used it in slate. I don't like it on marble and granite, but it color enhances slate without leaving an oily film. I have a way used the cream version. Not sure if the aerosol version is the same.

I would suggest honing with medium (400-800 grit) honing powder, but you may have to go up or down to get the best results. Also finish with SCI countertop polish which has some acrylic content, dries quickly and has a decent odor.
