DEFINITION

Classification: 75/722

Involving organic compound containing metal or organic agent for agglomerating metal:

(under subclass 711) Process wherein an organic compound containing a metal (e.g., complex, solvent, resin, etc.) is involved at any stage in the process or process wherein an organic agent for agglomerating free metal (e.g., collecting agent, flocculation agent, flotation agent, etc.) is

involved.

(1) Note. Processes treating metalliferous materials and producing or recovering organo-metallic complexes without free metal production should be placed in the appropriate Organic Chemistry Class. However, if a free metal is produced, proper classification is in Class 75.
