A dust survey was carried out in a group of eight haematite mines, prior to the use of water for dust control, and was repeated later, when practically all dustproducing sites were subjected to wet treatment. No changes in ventilation or other procedure were made in the intervening period. Settled dust samples had been shown to contain from 9 per cent. to 16 per cent. of free silica, and the ...

Pyrite and Coal Mining. Sulfur occurs in coal in three different forms: 1) organic sulfur, 2) sulfate minerals, and 3) sulfide minerals (mostly pyrite with minor amounts of marcasite). When the coal is burned, these forms of sulfur are converted into sulfur dioxide gas and contribute to air pollution and acid rain unless they are removed from the emissions.
