Abstract

Claims (17)

1 . A process for producing a metal from its ore comprising:

smelting; wherein the smelting comprises reducing, using a reducing agent, the ore, thereby decomposing the ore; wherein the reducing is achieved using a biogenic blast furnace addition composition; and wherein the biogenic blast furnace addition composition comprises:

at least about 85 wt % total carbon;

at most about 5 wt % hydrogen;

at most about 1 wt % nitrogen;

at most about 0.035 wt % phosphorus;

at most about 0.6 wt % sulfur;

at most about 1.5 wt % volatile matter;

at most about 13 wt % ash;

at most about 8 wt % moisture;

a CRI value of about 30 or less;

dimensions from about 5 cm to about 25 cm; and

an additive selected from a metal, a metal oxide, a metal hydroxide, a metal halide, an acid or a salt thereof, a base or a salt thereof, or a combination thereof.

2 . The process of claim 1 , wherein the additive comprises an alkaline earth metal, an oxide of the alkaline earth metal, a carbonate of the alkaline earth metal, a derivative of the alkaline earth metal, a derivative of the oxide of the alkaline earth metal, or a derivative of the carbonate of the alkaline earth metal.

3 . The process of claim 1 , wherein the additive comprises calcium, calcium oxide, calcium carbonate, magnesium oxide, or magnesium carbonate, or a derivative thereof.

4 . The process of claim 1 , wherein the biogenic blast furnace addition composition further comprises at least about 0.5 wt % to at most about 1.5 wt % volatile matter.

5 . The process of claim 1 , wherein the biogenic blast furnace addition composition further comprises at least about 2 wt % to at most about 15 wt % dolomite, at least about 2 wt % to at most about 15 wt % dolomitic lime, at least about 2 wt % to at most about 15 wt % bentonite, or at least about 2 wt % to at most about 15 wt % calcium oxide.
