    Iron ore. ArcelorMittal Liberia’s iron ore is a direct shipped iron ore (DSO) product. DSO means that apart from some primary crushing, screening and blending at the mine, the iron ore is mined, shipped and consumed in about the same form as it is extracted from the ground. DSO is a sintering fines material. It is sold to steel mills and used ...What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.
