Refining (metallurgy) Wikipedia,In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer. [clarification needed] The processes used are of many types, including

Copper Mined vs Copper Refined (by Country),Taking a closer look at worldwide copper production statistics we found that some of the biggest copper producing countries do not necessarily refine the copper at home. The reasons for this depend on various factors. We wanted to find out how much of copper is not actually refined in the same countries from which it was mined.
Refined Copper Industry February 2021 update,Refined copper production fell by a sharp 24.4% to 231.7 thousand tonnes during Apr-Dec FY21 compared with Apr-Dec FY20. Overall domestic refined copper production fell sharply by 39.5% y-o-y in Q1FY21 impacted by the lockdown which brought business activities to a sudden halt. However the de-growth was substantially lower at just 4.2% y-o-y in Q2FY21 as favourable monsoon helped lift rural
