A process for the recovery in a usable condition of one or more components of grinding swarf comprises grinding and screening the swarf where necessary mixing and washing it first with a hydrocarbon or chlorinated hydrocarbon combined with a surfactant and the removal of the bulk of the resulting solution is effected following which the resulting swarf is then washed one or more times with a
