    This step involves breaking up the iron ore to obtain an F 80 grind size before it can be ground. Once the ore has been crushed, it is diverted to a stockpile. The aim of this step is to ensure a smooth crushing process and minimize downtime in the event of a breakdown or to allow planned maintenance in the crushing system, without stopping the grinding and other further steps. If the crusher

    Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO
