Poling (metallurgy) Wikipedia

Poling (metallurgy) Wikipedia

Poling is a [metallurgical] method employed in the purification of copper which contains copper oxide as an impurity and also in the purification of tin ("Sn") which contains tin oxide (stannic oxide or "SnO 2") as an impurity. The impure metal, usually in the form of molten blister copper, is placed in an anode furnace for two stages of refining.

STEP 3 – Settling: Settling is achieved primarily by using gravity, although some chemicals are added to aid the process. Just as a glass of sugar water with fine sand suspended in it will separate out over time, the impurities in the slurry things like sand and iron and other trace elements that do not dissolve will eventually settle to the bottom.
