[Solved] Which chemical process is used in smelting

Smelting : The reduction of oxide ore with Carbon at high temperature is known as Smelting. Fe 2 O 3 + 3C → 2Fe + 3CO; PbO + C → Pb + CO; Explanation: In the example reaction, we can see that the reduction of metal ore is there. Fe 3+ is converted to Fe 0 while in other reaction Pb 2+ is changed to PB 0 i.e reduction of the metal. Notes

Silver processing Britannica

2020-8-14  The smelting and converting of copper sulfide concentrates result in a “blister” copper that contains 97 to 99 percent of the silver present in the original concentrate. Upon electrolytic refining of the copper, insoluble impurities, called slimes, gradually accumulate at the bottom of the refining tank.
