Introduction Iron ore is one of the most important natural raw materials that is widely used for manufacturing iron and steel. This type of ore contains various amounts of radionuclides; thus, exposing workers handling their extraction, transportation, and processing to radiation. Materials and Methods In this study, 12 ore samples (each mass weighing about 2 kg) were collected from the iron or...

KiG No. 26, Vol. 1 5, 201 6 88 melted in Rude, in a blast furnace with an annual capacity of 25,000 cents, one part ofwhich was transported to Slovenia. Annual production of iron ore was between 20,000 and 130,000 cents, while annual production ofiron was between 5,000 and 16,000 cents. The mine was closed in 1859 due to unprofitability. Twenty-six thousand tons ofore were extracted during the ...

In this paper, iron ore sample from the Chadormalu was investigated to determine some comminution properties. Chadormalu deposit is one of the largest iron ore mine in Iran, which is located in Yazd province. The representative ore sample contained 57%Fe, 0.9%P and 0.17%S. The sample was crushed; afterward, it was ground in various grinding times according to the Bond Ball mill approach to spec...

The extraction of ore and minerals by underground mining may induce ground subsidence phenomena. These phenomena produce several types of ground movement like horizontal and vertical displacements, ground curvature and horizontal ground strain at the surface, and associated building damage in urban regions. The influence function is a well-known and efficient method for the prediction of these ...

LKAB’s Kiruna Mine is located above the Arctic Circle in northern Sweden, and produces about 24 million tons of iron ore per year, making it is the second largest underground mine in the world today. The orebody, a world-class high-grade magnetite deposit, is approximately 4 km long and 80 m wide on average, and lies roughly in the north-south direction, with a dip of some 60 degrees. Surface m...
