Base metals smelters and refineries: code of practice overview
The code of practice for base metals smelters and refineries has been in effect since March 2006.
This code of practice aims to identify and promote recommended practices as requirements for new facilities and as goals for continual improvements for existing facilities.
The code of practice applies to base metals smelters and refineries including producers of:
- primary copper
- primary and secondary lead
- primary zinc
- primary nickel
- primary cobalt
Adopting the code of practice
If the code of practice applies to your facility, you are encouraged to implement applicable recommended practices.
