Adding Steam to Control Dust in Mineral Processing.

The Bureau of Mines performed tests to compare the effectiveness of steam and of water sprays to reduce respirable dust levels at mineral processing plants. By applying 0.22 Wt pct water vapor as steam to product material, a 64-pct respirable dust reduction was recorded. By applying the same amount of moisture with water sprays, only a 25-pct dust reduction was recorded. By increasing the moisture content up to 0.5 pct using water sprays, the dust reduction was increased to 55 pct, which was still less than the dust reduction achieved by adding less than half that amount of water in the form of steam.
