AbstractRed iron oxide which is produced by regeneration of waste hydrochloric acid from steel pickling line contains chloride. Chloride has negative effects on industrial productions which use red iron oxide as a raw material. This paper asserts red iron oxide particles have different chloride content according to their particle size. Regenerated red iron oxide was sampled from different production batches and these samples were grouped according to their particle size with sieving them from 1 mm to 75 µm. Sieved red iron oxide samples were analysed with spectrophotometer to determine chloride content. The study found out that chloride content slightly increased by increasing particle size up to 710 µm, after that size chloride content was drastically increased, such that, removing particles bigger than 1 mm from the iron oxide provides a 11,97 % reduction of the total chloride content and causes only 0,27 % loss from the total material.
