The invention concerns a method for control of the properties of the remaining oil layer on magnesium or magnesium alloy particles and/or other reactive metal particles produced from molten metal. The particles are cooled in a cooling oil with subsequent centrifuging and heating to remove remaining oil. A part of the oil layer on the particles is replaced with a lighter oil, preferably during centrifuging. The oil can be supplied as a spray. The light oil is supplied in an amount of 0.5-10 weight %. The light oil used should have a viscosity <5 cP at 25 DEG C. and a flashpoint <100 DEG C. Preferably it is used oils having a viscosity <2.5 cP and a flash point between 30 DEG and 75 DEG C. It is preferred to use dearomatized oil.
