name the common element present in the anode mud in electro refinig of copper.

ANTOMONY ,STRONSIUM,SELENIUM,TELLURIUM,SILVER,GOLD AND PLATINUM . THESE ELELMENTS ,BEING LESS REACTIVE ,ARE NOT AFFECTE BY CuSO₄+H2SO4 SOLUTION AND SETTLE DOWN ANOD AS MUD

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.

During electrolysis, pure copper is deposited on the cathode plates and impurities which are soluble and fall to the bottom of the cell as anode mud.
