Abstract
A metallurgical process involves providing an ingredient enclosure and placing a plurality of granules of a first material in the ingredient enclosure. The first material contains a first ingredient in a metallurgical process. A metallurgical process furnace having a chamber in which ingredients for the metallurgical process are added is provided and the ingredient enclosure and the first material are added to the chamber. The chamber is heated after the addition of the ingredient enclosure and the first material to the chamber, although it may also be heated prior to such addition. In one form, the granules comprise mill scale and the metallurgical process furnace is a blast furnace.

A metallurgical process carried out in a furnace, the process comprising:
- providing a burden above the liquid iron in a furnace, the burden comprising sources iron, and flux;
- providing a plurality of ingredient enclosures that contain at least one ingredient for carrying out a metallurgical process in the furnace;
- pre-determining a desired lateral distribution of a first set of ingredient enclosures;
- distributing the first set of ingredient enclosures to desired locations on top of the burden while taking into account the pre-determined desired distribution;
- applying heat to the burden;
- opening at least one ingredient enclosure by the application of heat for a period of time;
- and
- exposing the contents of the enclosure to the liquid iron.
A metallurgical process comprising:
- providing a first ingredient enclosure having a vent;
- placing a first layer comprising a first contaminated material covered by a second layer comprising second less contaminated material in the first ingredient enclosure;
- providing a metallurgical process chamber in which ingredients for the metallurgical process are added;
- adding the first ingredient enclosure and the first and second materials to the chamber;
- applying heat to the enclosure;
- opening the first enclosure by the application of heat for a period of time to expose the first material to the chamber.
