iron chelation therapy is used to reduce iron overload development due to its deposition in various organs such as liver and heart after regular transfusion. in this review, different iron chelators implicated in treatment of iron overload in various clinical conditions have been evaluated using more up-to-date studies focusing on these therapeutic agents. deferoxamine, deferiprone and deferasi...

The demands for increasing the efficiency and lowering the environmental effects in iron and steelmaking industries have given rise to interests in application of direct reduction (DR) processes for production of iron by different gases. These advancements require comprehensive models for better control of the process conditions and the product properties. In the present thesis fundamental aspe...

The mortality of 1947 Cumbrian iron ore miners has been studied over the period 1939-82 in relation to that among other groups of men in England and Wales: (a) all men, (b) men of similar social class, and (c) men living in similar types of (mainly rural) area. Significant excesses were found for deaths from tuberculosis and respiratory diseases compared with each of the reference populations. ...

This work presents the mathematic models of the basic processes from an iron ore processing plant. Based on the mathematic models, using the Matlab/Simulink platform, it was achieved the simulation of the dosing process and simulation of the sintering process. The achieved mathematic model allows the determination of the material flows in the charge at their chemical composition variation, or a...

This paper describes a 3D stockpile modelling algorithm to improve quality control and increase operational efficiency in iron ore handling. The 3D model, generated from real measuring data, approximates a stockpile using a group of 3D volumetric element, which able to store information inside it, such as quality compositions of the ore. By associating this model with the cutting geometry of a ...

Feasibility study of the mining operation is one of the most important parts of the total mineral exploitation process. The economic importance of this, increases with the size of the mineral reserves. Gol-Gohar is one of the largest iron ore mines in Iran with an annual output of some 11 million tons. In this paper, the total costs associated with Gol-Gohar open cast mine have been calculated....

During the past two years an extensive and a very interesting program of malaria control has been in progress in the town of Chimbote, Peru. Chimbote lies on the cost of Perú about 250 miles north of Lima, and is, at the present time, a small fishing village of about 4,000 persons. Plans have been made to develop the Chimbote area into a large industrial center, and it is in connection with thi...

The processing mineralogy characteristics of an oxidized lead-zinc ore from Sichuan were studied systematically using numerous modern instruments. Results showed that lead and zinc oxide content in the ore exceeded the minimum industrial grade, and also included a relatively high concentration of silver and iron. This ore is composed of many different minerals. Major zinc-containing minerals in...

A new species of Archaea grows at pH approximately 0.5 and approximately 40 degrees C in slime streamers and attached to pyrite surfaces at a sulfide ore body, Iron Mountain, California. This iron-oxidizing Archaeon is capable of growth at pH 0. This species represents a dominant prokaryote in the environment studied (slimes and sediments) and constituted up to 85% of the microbial community wh...

Ballast water treatment consists of the elimination of exotic species. Currently, the development of alternative methods for this process is directed toward treatment onboard ships. However, we present onshore treatment as a viable alternative for ballast water treatment. We investigated onshore treatment in two iron ore ports with movement capacities of 25 and 90 million tons annually (Mta) th...
