Abstract
Provided is a method for transporting reductant such as coke into a metallurgical furnace containing a bottom layer containing molten metal and a top layer on top of the bottom layer containing molten metal. The method comprises a first providing step for providing reductant, a second providing step for providing metal, a forming step for forming carriers containing reductant and metal of reductant provided in the first providing step and metal provided in the second providing step, and a feeding step for feeding carriers formed in the forming step into the metallurgical furnace. Also provided is a carrier and a production method for producing carriers.

A method for transporting a reductant into a metallurgical furnace containing a bottom layer containing molten metal and a top layer on top of the bottom layer,
- wherein the method comprises:
- providing a reductant,
- providing a metal,
- forming carriers containing the reductant and the metal, and
- feeding the carriers containing the reductant and the metal into the metallurgical furnace,
- wherein the carriers have a density of 110 to 190% of the density of the top layer in the metallurgical furnace and a density that is lower than the density of the bottom layer containing molten metal in the metallurgical furnace, and wherein the carriers contain in mass percentage between 10 and 70% copper, the rest being reductant and optionally binder and impurities originating from the reductant and/or originating from the copper.
