Division BAT 140
United Kingdom
In order to reduce dust and metal emissions to air from all dusty operations, such as crushing, sieving, mixing, melting, smelting, incineration, calcining, drying and refining, BAT is to use one of the techniques given below.
| Descriptions of the techniques are given in Section 1.10. | ||
| Techniquef1 | Applicability | |
|---|---|---|
| a | Bag filter | May not be applicable for off-gases containing a high level of volatilised selenium |
| b | Wet scrubber in combination with an ESP, allowing the recovery of selenium | Only applicable to off-gases containing volatilised selenium (e.g. Doré metal production) |
BAT-associated emission levels: See Table 39.

BAT-associated emission levels for dust emissions to air from all dusty operations, such as crushing, sieving, mixing, melting, smelting, incineration, calcining, drying and refining
| As a daily average or as an average over the sampling period. | |
| Parameter | BAT-AEL (mg/Nm3)f2 |
|---|---|
| Dust | 2-5 |
