A number of compressive tests were conducted on iron ore pellets obtained from the Samarco pelletiing plant located at Ponta Ubu Brail. These pellets are formed by disk pelletiing of a mixture consisting of hematite iron ore particle sie less than 50 181m water and lime they are hardened in a traveling

Slow compression tests are routinely used both in quality control of fired iron ore pellets during production and in negotiating commercial contracts. In spite of their widespread use such tests represent stressing conditions consistent with those experienced by pellets during transportation in ships wagons and conveyor belts as well as when they are stored in silos and hoppers

Composite briquettes or pellets consisting of iron ore carbon and a binder are a source of direct reduced iron DRI. In the handling of green and reduced briquettes high strength is important to minimie briquette breakdown. The use of charcoal as a source of carbon rather than coal provides a way of introducing renewable carbon into the ironmaking process
