Metals like potassium and sodium react vigorously with oxygen and catch fire if kept in open. Hence they are stored in kerosene to prevent burning. If magnesium is heated, it burns with a bright flame. If iron is heated it glows brightly. If copper is heated it does not burn but forms a black coating of copper oxide.

12.3 Primary Copper Smelting

The fire-refined copper is then cast into anodes for even further purification by electrolytic refining. Electrolytic refining separates copper from impurities by electrolysis in a solution containing copper sulfate (Cu2SO4) and sulfuric acid (H2SO4). The copper anode is dissolved and deposited at the cathode. As the copper anode dissolves ...

Copper - Essential Chemical Industry

The process is known as fire-refining. The still impure copper is then cast into anodes for electro-refining. (ii) The leaching process. Copper is obtained from its ore by treating the ore with a solution of copper(ll) chloride and iron(lll) chloride: Copper is recovered in the form of copper(l) chloride.

Copper Refining: Explained Step-by-Step

In refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than has copper.In these operations some of the copper is oxidized to cuprous oxide and dissolved by the metal bath.
