Method for refining and homogeneously distributing alloying partners and for removing undesired reaction products such as oxides and/or slag in or from soft solder during the production of fine solder powder, in which the solder alloy is melted in a high temperature-resistant plant and/or animal oil, the melt is moved to another container of oil with a temperature of at least 20.degree. C. greater than the liquidus temperature, stirred there, and subjected to multiple shear treatments using rotors and stators for forming a dispersion comprising solder balls and oil, from which dispersion the solder balls are separated by means of subsequent sedimentation.
