To re-finish a slate blackboard that has been gouged and scratched you will need to balance your expectations with the amount of work you will need to do to get a good flat, smooth surface on the slate.
If it were I, presented with a really carved-up face, I would turn the bad side to the back and make the back side the new face by progressively finer sanding with a wide sanding block, broad strokes and lots of elbow grease. The reverse side is probably nearly smooth, already, but you will want to take it down, ultimately, with a very fine grit sandpaper in the over-1000 grit range and finish it by washing it with water, allowing it to dry then chalking it. To chalk it, use a piece of chalk on its side to completely cover the board and erase the board with a felt eraser. This 'primes' the surface.
