The copper droplets contained in the post-processing liquid slag are subjected to the treatment by the complex reagent. The complex
reagent has been recently elaborated and patented in frame of the Grant No. PBS3/A5/45/2015. In particular, the complex reagent is
dedicated to the post-processing slags coming from the Smelter and Refinery Plant, Głogów, as a product of the direct-to-blister
technology performed in the flash furnace. The recently patented complex reagent effectively assists not only in agglomeration, and
coagulation but also in the deposition of the copper droplets at the bottom of crucible / furnace as well. The treatment of the postprocessing
slags by the complex reagent was performed in the BOLMET S.A. Company as in the industrial conditions which were similar
to those usually applied in the KGHM – Polish Copper (Smelter and Refinery Plant, Głogów). The competition between buoyancy force
and gravity is studied from the viewpoint of the required deposition of coagulated copper droplets. The applied complex reagent improves
sufficiently the surface free energy of the copper droplets. In the result, the mechanical equilibrium between coagulated copper droplets
and surrounding liquid slag is properly modified. Finally, sufficiently large copper droplets are subjected to a settlement on the crucible /
furnace bottom according to the requirements.
