When dry grinding processes are used, PM emissions can be considerable. After final size reduction, the beneficiation of the ore increases the concentration of valuable minerals by separating them from the matrix rock. A variety of physical and chemical processes is

closer.) In four pairwise comparisons of emission factors/rates for the two size ranges, only the total particulate (TP) emission factors differ significantly between the present study and the 1993 program. Note that the TP results from the present study are expected to be somewhat greater because the earlier study employed a longer wind tunnel.

An emission factor relates the quantity (weight) of pollutants emitted to a unit of activity of the source. The uses for the emission factors reported in AP-42 include: 1. Estimates of areawide emissions; 2. Estimates of emissions for a specific facility; and 3. Evaluation of emissions relative to ambient air quality.
