extraction of zinc - introduction, mining, procedure, and faqs

Mar 11, 2021 The most commonly available ore in the extraction of Zinc is Zinc Blende also known as Zinc Sulphide (ZnS) and other ores include Calamine, Zincite, etc. Zinc Blende does not contain a very high percentage of zinc so it needs to be concentrated. The best concentration method for zinc ore is froth flotation. Procedure of Zinc Extraction

Zinc is extracted from either zinc blende/sphalerite ore (zinc sulphide) or sometimes calamine/Smithsonite ore (zinc carbonate). (1) The zinc sulphide ore is roasted in air to give impure zinc oxide and forming the nasty poisonous gas sulfur dioxide (sulphur dioxide). zinc sulfide + oxygen ==> zinc oxide + sulfur dioxide

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.There are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in
