5.4.2 Copper, copper oxide. When a ship or another solid body (seashore building, landing stage, pier, etc.) immerses into (sea)water, antifouling paints with pure copper powder or cuprous oxide content are exposed to water. Copper is a highly effective antifouling agent that deters growth of marine organisms.

Extraction of copper from cuprous oxide. The majority of the ores are sulphide, with some containing iron. Sulfide ores are roasted/melted to produce oxides: 2Cu 2 S + 3O2 → 2Cu 2 O + 2SO 2. Using coke, the oxide can then be easily reduced to metallic copper: Cu 2 O + C → 2 Cu + CO.
