A furnace used in pyrometallurgical copper refining in which copper is cleaned in a combined rinsing and reduction process (known as poling) and anode copper produced by reducing the copper’s oxygen content.

A product of the copper tankhouse which settles on the bottom of an electrolytic cell as the copper anodes dissolve and which also adheres to the remains of the anodes. The precious and non-soluble components of the anode are enriched in the anode slimes (e.g. silver, gold, selenium, lead).
