Suppression of airborne particulates in iron ore

Dec 08, 2009· 1. Introduction. The inadvertent generation of airborne particulate matter (PM) at iron ore processing plants can be a significant problem. During handling and transportation, the taconite pellets produced at the plants are subjected to abrasion which results in the generation of large quantities of fine material (Petavratzi et al., 2005).These fine particles can easily become airborne

Environmental impact of iron ore mining Wikipedia

Introduction Iron ore. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)·n(H 2 O)) or siderite (FeCO 3).Roughly 98% of iron ore on the global market is

A Look at the Process of Pelletizing Iron Ore for Steel

This processing works to transform raw, mined iron ore into a concentrated powder suitable for pelletizing. In addition to mined iron ore, other sources of iron, such as flue dust collected from blast furnaces, or the dust produced at mine sites, is also frequently pelletized so it can be utilized, as opposed to disposed of. The Pelletizing Process

Airway inflammation in iron ore miners exposed to dust and

The aim of the present study was to investigate if underground miners exposed to dust and diesel exhaust in an iron ore mine would show signs of airway inflammation as reflected in induced sputum. In total, 22 miners were studied, once after a holiday of at least 2 weeks and the second time after 3 months of regular work. Control subjects were 21 “white-collar” workers.

Nov 01, 2005· Handling taconite pellets produces dust. As the pellets are transported, they abrade and produce a fine material that represents a concern for airborne dust. Pellet-breakdown studies revealed that as much as 43% (by weight) of the fine particles were 10 μm in diameter and smaller (material regulated by the U.S. Environmental Protection Agency). This is a significant amount of material that

Iron processing Iron making | Britannica

Iron processing Iron processing Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

Direct reduced iron Wikipedia

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
