    2.1. Dust Control Strategy The key method of dust management is ensuring sufficient moisture (water) is added to the ore, at the mine site, so that dust emissions are kept to a minimum during ore handling Metal Detection in Iron Ore Handling bulk-online,Nov 12, 2005· >>The second problem is that the host rock is magnetic in nature. The higher grade of ore, the more strongly it will be attracted to the magnet causing a loss of material. The magnetic susceptibility of the host rock will be dependent on the iron ore type. If there is magnetite or maghemite present then there may be a problem.

  • Storage of Metals Canadian Conservation Institute (CCI

    Because actively corroding pieces create dust, chloride, or staining problems by scattering corrosion products, they should be removed from the main collection and stored in a separate area with an RH below 35%. The drier conditions will reduce the corrosion rate, but the source of the corrosion will still need to be addressed.Environmental Risks of Mining,When companies break up materials during mining, the dust can release a variety of heavy metals commonly associated with health problems. As dust, these minerals (such as the asbestos-like mineral riebeckite) can be absorbed into lung tissue, causing problems like pneumoconiosis and silicosis, commonly known as "Black Lung" (Paul & Campbell, 2011).
