introduction the lulak abad iron occurrence is located in the northwestern part of the central iran, 55 km west of zanjan. mineralization at the lulak abad area was originally identified by zamin gostar company (2007), during a geophysical exploration. the present paper provides an overview of the geological framework, the mineralization characteristics, and the results of a geochemical study o...

Iron ore and coal together account for about 72% of cost of input materials in Indian steel plants. Moreover, sourcing iron ore and coal for steel plants is posing multitude of challenges including availability, quality and logistics. At present it is found that high quality input materials are hard to reach and easy to reach ones are of lower quality. Hence efficient utilisation of lower quali...

Iron ore occurrences are situated on the south-eastern slopes of the Medvednica Mountain. They occur as discontinous, decameters long and 2-3.5 m thick bedded, poorly mineralized (15-35 % Fe) lenses. A narrow, 6 km long, ore zone strikes NE-SW from Tisova Peć to Pustodol-Adolfovac. It is spatially and genetically bounded to the basic volcanogenic-sedimentary series (SEDEX-type), metamorphosed i...

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...

Concentrations of As and selected metals were determined in surface soils of the Miyun Reservoir watershed of Beijing, China. The degree to which concentrations of As and metals exceeded the corresponding background concentration of soils was: Cr>Cu>Zn>As>Ni with no apparent anthropogenic contamination with Cd and Pb. Based on the results of a combination of multivariate statistics and geostati...
