The thin copper wash blows off from the heat and pressure of the explosion in the chamber. The cases are just cheap steel, which makes picking them up afterwards super easy at least.

I've never seen an SKS shooter pick up after themselves. Seriously, those steel cases are like gravel on the ground at the range

Which is silly because it is so easy.

Our range has a wheeled magnet that you just run over the ground and grab all your steel cases. Everyone is pretty good about picking them up.
