Red ferrous oxide benification

The present invention relates to a process for producing red iron oxide with only marginal goethite content, wherein a ferrous chloride feedstock is employed as starting material. The process comprises precipitating lepidocrocite seeds having a high BET surface area by mixing the ferrous chloride feedstock with an alkali and oxidizing the obtained mixture, and growing the lepidocrocite seeds
