Make a solution out of it, pour in saturated sodium bicarb solution until no more carbon dioxide releases. Filterate the formed carbonate and
calcinate it by heating it in crucible. Scaling this up might be not a very good idea but in small scale it works fine.
Or the other (easier) way round 2SnCl2+O2+2H2O --> 4HCl+2SnO2
