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, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite (FeCO 3).Ores carrying very high
The equipment consists of a rotating drum into which dry ore samples are placed, with an impact paddle mounted on a centre shaft rotating at a higher speed than the drum. The paddle is made from standard alloy steel hardened to 500 Brinell. The Abrasion Index is determined from the weight loss of the paddle under standard operating conditions
