Epidemiological studies have shown an excessive incidence of lung cancer in miners with exposure to radon daughters. The various risk estimates have ranged from six to 47 excess cases per 10(6) person years and working level month, but the effect of smoking has not been fully evaluated. The present study, among a group of iron ore miners, is an attempt to obtain quantitative information about t...

   The Asinawa iron ore is located about 3km to the southeast of Penjween town, Sulaimaniya Governorate, Kurdistan Region, Northeastern Iraq near the Iraq-Iran border. The exposed iron ore deposit is about 60 and 400m wide and long respectively. The present study is the re-study of the geology and geochemistry of the Asnawan Iron ore deposit  and concluded that the country rocks are consist of ...

Introduction The history of haematite iron ore mining in the Cumberland and Furness districts has been excellently described by Kendall (1893), and from a summary of this and works by Smith (1924), the following brief facts have been taken. The date of the first working of haematite in Cumberland and Furness is uncertain, but the exposed veins in the Lake District must have been known long befo...

The present work evaluated two high-density polyethylene (HDPE) geomembranes exhumed from mining facility constructions in Brazil. MIN sample was a pond for water use the iron ore process after 7.92 years of exposure. MIN2 spillway channel ferronickel tailing dam 10.08 service. physical evaluations showed high depletion antioxidants that temperature range 200 °C. samples presented brittle tensi...

Rock-filled concrete (RFC) has good performance in terms of energy savings, cost reduction, and CO2 emissions as a novel massive construction technology. There have been studies into replacing natural rocks RFC with large blocks solid waste, this method used on several sites. However, the granular powdery waste utilized is limited, consequence special requirement self-compacting (SCC) RFC. The ...

Dilution can best be defined as the proportion of waste tonnage to the total weight of ore and waste in each block. Predicting the internal dilution based on geological boundaries of waste and ore in each block can help engineers to develop more reliable long-term planning designs in mining activities. This paper presents a method to calculate the geological internal dilution in each block and ...

Isobaric and cooling zone of iron ore reactor have been simulated. In this paper, heat and mass transfer equation are formulated to perform the temperature and concentration of gas and solid phase respectively. Temperature profile for isobaric zone is simulated on the range temperature of 873-1163K while cooling zone is simulated on the range temperature of 733-1139K. The simulation results hav...

Currently, approximately 1.4 billion tons per year of iron ore tailing wastes (IOT) are generated, mainly in Australia, Brazil, and China. This work describes the characterization application two typical IOT, i.e., fine coarse wastes. The physicochemical these IOT by different techniques such as XRF (X-ray fluorescence), XRD diffraction), Mössbauer spectroscopy, granulometry, indicates for a co...

The present research paper deals with the oxidation process of molybdenum ore. The main target of the present study is the up-gradation of MoO3 from roasted molybdenum ore by a leaching process without waste generation. The most important application of hydrometallurgical processing is the leaching process of the ore and it is the primary process to make pure metal from ore. The present investi...
