Turner examined the impact of dust generated by iron ore mining in Australia and concluded that dust reduced plant physiological performance by over 50% and reported a radius of dust transfer up to 2000 m. He reported the maximum dust was produced at less than 600 m from the mine with a significant change in plant physiological parameters ...

OSHA, (May 31, 2011). Any combustible material can burn rapidly when in a finely divided form. If such a dust is suspended in air in the right concentration, under certain conditions, it can become explosible. Even materials that do not burn in larger pieces (such as aluminum or iron), given the proper conditions, can be explosible in dust form.
12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the

Assessments of the likelihood of explosions can therefore be made on the basis of ore composition and tendency to fragment into the dangerous size range. Monitoring of atmospheric dust content is vital in controlling the hazard. Such monitoring yields not only the dust composition, concentration and size distribution but also points to the
Dust explosions in metalliferous mines have generally been associated with mining operations in massive pyritic or pyrrhotitic ore bodies. Other minerals with an appreciable sulphur content may form an explosive dust cloud; laboratory tests have shown that sphalerite dust can sustain an explosion. Sulphur Content of Common Sulphide Minerals
Basic rules to observe for dust to be capable of causing a dust explosion: The dust must be combustible; The dust must be airborne; The dust must have a size distribution capable of flame propagation; The dust concentration must be within the explosive concentration range; An ignition source with high enough temperature must be present
Dust is irritating to the respiratory tract. Inhalation of fumes may cause metal fume fever, which is characterized by flu-like symptoms with metallic taste, fever, chills, cough, weakness, chest pain, muscle pain and increased white blood cell count. Ingestion may cause severe and permanent damage to the digestive tract. May cause liver damage.
A common explosive used for blasting operations is ammonium nitrate/fuel oil (ANFO) mixture. The powder factor is the amount of explosives used per unit of rock blasted and varies depending on the rock type and strength. Data were collected on the powder factor for various mine blasting operations.
The environment is extremely dirty, with large amounts of highly explosive iron ore dust in the air. Ongoing lubrication is required for the loading mechanisms, railcar, and conveyor systems to keep iron ore …

Deposited mine dust is the fallen mine dust, referred to as fallout. According to the types and properties of the mineral and rock, mine dust can be divided into silicon dust, iron ore dust, coal dust, asbestos dust, radioactive mine dust, explosive mine dust, and toxic mine dust. According to particle size, mine dust can be divided into coarse ...
The combustible dust involved was a phenolic resin binder used in producing fiberglass mats. On the evening of Oct. 29, 2003, a series of explosions severely burned three employees, one fatally, and caused prop- erty damage to the Hayes Lemmerz manufacturing plant in Huntington, Ind.

Metal Dust Fire and Explosion: Indiana (1 killed, 1 injured) Finely dispersed airborne metallic dust can also be explosive when confined in a vessel or building. In October 2003, an Indiana plant where auto wheels were machined experienced an incident which was also investigated by the CSB. A report has not yet
Dust emission is one of the critical problems of the mining industry. Dust emission can cause respiratory diseases among workers and adjacent residents of the factory and environmental pollution in the region. This study aims to reduce dust emissions of an iron ore concentrate plant in Iran.
If such a dust is suspended in air in the right concentration, under certain conditions, it can become explosible. Even materials that do not burn in larger pieces (such as aluminum …
