Cement copper, a proper bulk cargo shipping name ( BCSN), is listed under the generic entry of "Mineral Concentrates" in the IMSBC Code. It is a refined ore. That is, valuable components are enriched by eliminating the bulk of waste materials. This cargo is also known as precipitated copper, a product obtained by precipitation (cementation), i.e., by adding iron to the aqueous solution resulting from the leaching of certain ores or waste. It is a finely devised black powder containing oxides and insoluble impurities. Cement copper is often added to the charge which goes to a converting furnace to produce copper matte. This cargo should not be confused with copper powder, which does not contain impurities.
