DEFINITION

Classification: 75/313

Composition for or from consolidating by agglomerating, calcinating, compacting, indurating, roasting, sintering, or solidifying from molten mass:

(under subclass 303) Composition which is: (1) intended for consolidation by agglomerating, calcinating, indurating, sintering, or solidifying from molten mass; (2) consolidated composition produced by agglomerating, calcinating, compacting, indurating, sintering, or solidifying from a molten mass, or (3) composition derived from materials which

were consolidated by agglomerating, calcinating, compacting, indurating, sintering, or solidifying from a molten mass.

(1) Note. This subclass takes as original consolidated metalliferous compositions amenable to Class 75 or Class 420 refining or alloying operation unless an intended use divergent from a Class 75 or Class 420 refining or alloying operation is the expressed use.

(2) Note. The consolidated composition may be a coated composition or may contain more than one layer. However, coated compositions produced by processes not involving agglomerating, calcinating, compacting, indurating, sintering or solidifying from molten mass go elsewhere under subclass 303 if they are coated charges, or coated solid treating compositions for molten metal.
