name the common element present in the anode mud in electrolytic refining of copper.why are they so present?
The elements that are present in anode mud are Tellurium, Selenium, Antimony, Gold, Silver and Platinum. Recovery of these elements may meet the cost of refining.
Copper, in its impure form is called blister copper. During refining, these impurities are removed which are known as anode mud.
In electrolytic refining of copper, the common elements present in anode mud are selenium, tellurium, silver, gold, platinum, and antimony.
These elements are very less reactive and are not affected during the purification process. Hence, they settle down below the anode as anode mud.
