• Description:
  The Bureau of Mines has studied a number of processes to remove cu from molten steel scrap with the objective of determining if any of the laboratory methods studied warranted in-depth research investigations. Experimental approaches included oxidizing cu from steel containing other metals that form stable mixed oxides with cu (al, cr, fe, mn, mo, and v), injecting the same metals as oxides to simplify the mechanism of complex oxide formation, partitioning cu into alkali or alkaline earth silicate slags or oxide-moderated sulfides, and co-removing cu and s by injecting active compounds of ca and mg. The most promising tests, producing nearly 0.3 pct cu in the slag, used ar injection of k2o-moderated na2s-fes below the surface of molten steel containing about 0.6 pct cu and protected by a cao-sio2 slag; however, in-depth research investigations currently are not felt to be warranted.
