Iron Oxide Scale (Mill Scale) – High Fe, Low Moisture, Graded Quality for Metallurgical Use

We export iron oxide scale, also known internationally as mill scale iron oxide or ferrous mill scale, to industrial buyers requiring a reliable iron oxide feedstock for metallurgical and thermal processes. The material is commonly supplied in iron oxide flakes, iron scale lumps, or iron oxide fines, depending on application and handling requirements. Shipments are prepared for buyers who require bulk iron oxide scale with predictable chemistry, controlled moisture, consistent chemical composition, and graded particle size, ensuring stable handling characteristics and suitability for heavy industrial operations such as sintering, pelletizing, blast furnace use, furnace charging, and other high-temperature reduction processes where predictable Fe recovery and uniform performance are important. Material is sourced, screened, and prepared to meet the operational needs of plants using steel mill scale as a secondary iron-bearing input. Shipments can be arranged in bulk or containerized form, with attention to lot-to-lot consistency, impurity control, and documentation required for cross-border trade, supporting global buyers who require defined specifications and dependable execution for metallurgical applications.
