Quemetco operates various furnaces (rotary dryer, reverberatory, electric slag, and refining pot-type), and air pollution control equipment such as scrubbers, baghouses, a regenerative thermal oxidizer (RTO), and a wet electrostatic precipitator (WESP).  The furnaces are enclosed in a building which is vented to several room ventilation air pollution control dust collectors equipped with primary filter bags and secondary high efficiency particulate air (HEPA) filters.
