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, whereby the lepidocrocite converts into red iron oxide. |
