Mining Of Zinc - Zinc

Process Of Zinc Mining At first, the zinc ore is crushed in the zinc mining equipment and the zinc ore is miledl after it is moved to the crushing place. The raw material used for the production of zinc is zinc concentrate, which is the result of a flotation process after the ore has been mined and crushed.

Zinc: smelting, producing and classification-Metalpedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method. Secondary (recycled) zinc material, such as zinc oxide, is also processed with the zinc sulfide.
