Abstract

The invention provides carbon carriers of improved reactivity suitable for use in slag-forming electrothermal reduction processes. The improved carbon carriers contain 5 to 80 weight % of the particular slag formed in the reduction process. The invention also provides a process for making the carbon carriers.
