Goethite

Goethite (CAS 1310-14-1), the naturally occurring iron oxyhydroxide mineral alpha-FeOOH, is a primary source material for iron-based pigments and a key reference compound in metallurgical and mineralogical analysis.

Its stable yellow-brown coloration and iron content make it commercially relevant across pigment production and mineral processing sectors. In pigment manufacturing, goethite serves as the base material for synthetic yellow iron oxide pigments.

These pigments are used in paints, coatings, concrete colorants, and construction materials. Cement and concrete producers use iron oxide derived from goethite to achieve consistent, lightfast coloration in architectural and infrastructure applications.

In mining and hydrometallurgy, goethite precipitation is a controlled process step for removing iron from leach solutions during zinc, copper, and nickel refining. This ensures high purity in the final metal extraction process.

Research and quality laboratories also use reference-grade goethite as a calibration standard for XRD analysis and iron speciation studies. It is essential for accurate mineralogical characterization in industrial labs.

Goethite is available as a fine powder in both natural mineral and synthetically produced forms. Synthetic grades offer tighter particle size distribution and higher purity, suited to pigment and analytical applications.

Supply specifications vary by iron content and particle morphology, with technical and reference-grade material available depending on end-use requirements. This versatility supports a wide range of industrial chemical processes.
