cost reduction is one of the methods applied for improving the productivity of organizations. in productivity literature, particularly in nonparametric methods, cost reduction related methods are regarded as input oriented models. this paper presents a supply chain management (scm) model in which purchasing iron ore and coke from different resources, along with production and distribution of st...

Please cite this article in press as: Bergquist, B. The ability to track and trace products in a production process and in the transportation chain from supplier to customers is important for quality control and process improvements. However, good traceability is often difficult achieve for continuous process products as well as for batch produced products where batches intermix. In this paper,...

Abstract— Based on Sm–Nd data, a crustal source of iron-ore fluid was substantiated and the probability age estimation for hydrothermal–metasomatic siderite Bakal Group, Southern Urals, shown first time. The εNd (Т) values (from –13.4 to –17.6) plot in field Riphean shale not Precambrian rift gabbro granite this region. obtained is 970 ± 40 Ma, which consistent with Pb–Pb from major ore phase (...

OBJECTIVES An excess of mesothelioma has been observed in iron ore miners in Northeastern Minnesota. Mining and processing of taconite iron ore generate exposures that include elongate mineral particles (EMPs) of amphibole and non-amphibole origin. We conducted a nested case-control study of mesothelioma in a cohort of 68,737 iron ore miners (haematite and taconite ore miners) to evaluate the a...
