ABSTRACT
This handbook consolidates information developed by industry and government laboratories on dust control engineering
techniques for metal and nonmetal mineral processing. The concepts of dust, its prevention, formation and control are
examined, including wet and dry control systems, personal protection, and testing methods. Costing methodologies are also
examined. Prospective users of this handbook include maintenance foremen, plant engineers, mill supervisors, and
safety directors or similar position. The information is described and illustrated in a manner to assist one skilled in mineral
processing but not necessarily skilled in dust control, to have enough information to implement a dust control technique without
need to refer to other sources.
