Abstract
A metal melt is filtered by causing the melt to flow successively into a filter chamber, downwards through the filter chamber, into a riser chamber, upwards through the riser chamber, and out of the riser chamber, and simultaneously introducing a counter-current flow of gas into the filter chamber, while the filter chamber contains a loose bed of granulate, whereas in the riser chamber there is no granulate nor is gas introduced therein.
