Metals from Ores: An Introduction
characteristic crystalline form. Ores are a mixture of minerals: they are processed to yield an industrial mineral or treated chemically to yield a single or several metals. Ores that are generally processed for only a single metal are those of iron, aluminium, chromium, tin, mercury, manganese, tungsten, and some ores of copper. Gold ores

Evidence for Surface Precipitation of Phosphate on Goethite
Recent studies have suggested that the interaction between phosphate and goethite includes ternary adsorption/surface precipitation as well as surface complex formation. The ternary adsorption/surface precipitation process envisioned involves the dissolution of the goethite crystal and subsequent adsorption of iron on the surfacebound phosphate.
