What is iron ore Iron ores are rocks and minerals rich in iron oxide that can produce metallic iron when smelted Due to the nature of the iron oxide present in iron ore they can range in color from dark grey to a deep red The iron in such ores is commonly found in the form of magnetite hematite goethite limonite and siderite
MINING AND BLASTING The underground mine is accessed via a spiral decline from surface to the 680m level and a 9m diameter 763m deep shaft equipped with three automatic Koepe hoists and capable of handling 5Mt/y of ore Underground development began in 1978 and the shaft was commissioned in 1982
