N2 - Two methods of industrial recycling of magnesium scrap using flux and without flux are described. Refining fluxes work by picking up oxides from the melt in the recycling process. The quantity of salt is determined by the content of oxides in the material because MgO has a thickening effect on the flux. Recycling of class 1 scrap requires little to no salt, whereas material with a higher oxide content needs more salt. Molten refining fluxes adhere to oxide layers but not to the magnesium melt. Flux-free recycling process is used for scrap with low contents of oxides, like class 1 scrap. It will never replace the flux-based process. Fluxless recycling of magnesium and magnesium alloys is widely applied as an in-house process by many die casters. The formation of dross takes place mainly in the melting furnace. Oxides and intermetallic particles are removed periodically from the melt surface and from the bottom of the melting crucible.
