Mining and Mineral Processing Sites
Three kinds of attack
Dust. Crushing, hauling and wind raise fine mineral dust that clogs fins and erodes surfaces.
Acid gases. Smelting and roasting of sulphide ores release sulphur dioxide, which forms acid in the moisture film on coils.
Process chemicals. Leaching and processing use acids and other chemicals, and their mist reaches equipment nearby.
Remote sites
Mines are often far from service centres. A corroded coil or radiator can mean weeks without cooling or standby power, so it pays to protect equipment before it ships.
ISO 9223 corrosivity category
Typical category for this environment: C4–CX.
- C1Very low
- C2Low
- C3Medium
- C4High
- C5Very high
- CXExtreme
Recommended protection by area
| Condition | ISO 9223 | Recommended system | Note |
|---|---|---|---|
| Smelters, roasters, acid plants | CX | PG-C Air-dry 2K | Acid gases; review the site before specifying. |
| Processing plant and leaching areas | C5 | PG-C Air-dry 2K | Acid mist and splash near process equipment. |
| Mine offices, camps and control rooms | C4 | PG-S1 Polysiloxane sol-gel | Dust and distant emissions; filter the intake air. |

Does coating protect against abrasive dust?
Only partly. Dust erodes films and clogs fins; filtration and gentle cleaning matter as much as the coating. Coating protects against the chemical attack that follows.
Why coat before shipment for remote sites?
Field coating at a remote mine is slow and hard to control. Coating before shipment gives full coverage and a batch record, and the equipment arrives ready to install.
