Abstract:
The invention relates to a pelletizing feed containing chromite ore, at least one nickel salt, and silicon carbide as the only carbonaceous material and the only reducing agent. The invention also relates to process for manufacturing the pelletizing feed comprising the steps providing chromite, at least one nickel salt and silicon carbide, and mixing chromite, at least one nickel salt and silicon carbide. The invention also relates to use of the pelletizing feed as a starting material for the manufacture of sintering feed. The invention also relates to a sintering feed in the form of pellets containing the pelletizing feed. The invention also relates to sintered pellets containing the sintering feed. The invention also relates to process for manufacturing the sintered pellets. The invention also relates to use of the sintered pellets as a component of smelting feed. The invention also relates to smelting feed comprising sintered pellets. The invention also relates to process for manufacturing ferrochrome alloy. The invention also relates to ferrochrome alloy obtainable by the method.
