Dust control in coal preparation and mineral processing plants. Information Circular/1990

Advantages and disadvantages of basic dust control techniques presently used by U.S. coal prep and mineral processing plants are briefly evaluated. These include ventilation, baghouse-type collectors, wet scrubbers, electrostatic precipitators, source control, sprays, personal protection devices, and good housekeeping. Two specific problems in these types of operations are also considered: dust collector system duct clogging, and control room dust control. Information provided in the report results from dust control research projects conducted by the Bureau at various coal prep and mineral processing plants over the past decade to reduce workers' dust exposure.
