STUDY OF PERSPECTIVE COMPOSITIONS FOR CASTING COPPER ANODES
Casting of copper into anodes is final stage of copper pyrorefining. Currently at Copper plant of Norilsk Nickel MMC PJSC in order to protect casting form from rapid wear and prevent welding of anodes to it during casting, the casting forms are filled with a solution of heat-resistant coating based...
