This paper gives a critical review of all relevant, published works on the stratigraphy, tectonics, magmatism, metamorphism and metallogeny of the metamorphic complex of the Drina-Ivanjica Formation in eastern Bosnia-western Serbia. Special attention was paid to all unresolved or controversial issues in geology and metallogeny of this area. The basic controversial geological problem is the ques...

the present study relies on determination of diet by adapting analysis on carbon and nitrogen stable isotopes extracted from dental collagen of twelve human skeletons buried in iron age grave situated in gohar tapeh archaic settlement at eastern region of mazandaran province, locating on southern coast of caspian sea. the geographical and geometric evidences indicate that gohar tapeh zone is si...

Nigeria is blessed with abundant iron ore deposits of nearly 3 billion tonnes and other basic minerals for steel production including coal and limestone. Yet the Nigerian steel sector has collapsed principally due to shortage of raw materials particularly iron ore for the integrated steel plants and billets for the rolling mills. The privatization of the steel sector that was done in 2004-2005 ...

The process of developing an iron ore mine from exploration data through to informed mining decisions provides an example of a Complex Adaptive System. The detailed composition of an ore body (expressed as a “block model” of regularly spaced rectangular blocks) has to be estimated from initially sparse exploration data, based upon a limited number of drill holes. As planning proceeds, the data ...

The processes responsible for the transformation of banded iron formations to hard high-grade hematite ore, and their timing, remain poorly understood despite many recent advances. The paleomagnetic method allows for the estimation of ore genesis timing as a complement to other techniques. The effectiveness of the paleomagnetic method at dating, and testing proposed models for, the genesis of h...

Introduction: Demand for Australian mined iron ore has increased employment within this sector thus exposing increased numbers of workers to the harsh Australian climate. This study examined the influence of hot (>30C WBGT) environmental temperatures, consistent with working in North Western Australia, on iron ore mining staff. Methods: Core temperature, hydration status, perceived exertion, mo...

due to the abundance of the non-coking coal and limitations as well as the high costs of the natural gas, the presentstudy examined the direct reduction of hematite (iron oxide) ore in the temperature range of 800-1000 °c by thenon-coking coal volatiles. approximately, 74.9% of the total amounts of volatiles and gases exit the coal up to800°c. the onset temperature to exit volatiles from the no...
