Smelting - an overview | ScienceDirect Topics

The U.S. Environmental Protection Agency now requires 95% or better of the sulfur in processed ores to be contained during smelting. Crushing and dry grinding stages as well as final rotary drying are likely to contribute the most to dust losses. Ore grinding wet avoids dust problems for this stage, and improves control of the final particle size.
