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

Zinc smelting

Overview

Although some zinc artifacts appear to have been made during classical antiquity in Europe, the first production of zinc in quantity seems to have been in India starting from 12th century and later in China from 16th century. In India, zinc was produced at Zawar from the 12th to the 18th centuries. The sphalerite ore found here was presumably converted to zinc oxidevia roasting, although no archaeological evidence of this has been found. Smelting is thought to have been done in sealed cylindrical clay retorts which wer

Zinc ore and mines Minerals and mines Foundations of

Zinc ore occurs in two types of deposit as primary zinc ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary mineral veins. Zinc ore is most commonly found as zinc carbonate (ZnCO 3), known as calamine or smithsonite. It generally occurs as rounded, crystalline crusts or granular, honeycombed masses that

Zinc Essential Chemical Industry

However, any iron sulfide present in the ore will be converted to iron(III) oxide, which reacts with zinc oxide to form zinc ferrite In the simple leaching process, this zinc cannot be easily recovered and so ores with low iron content are preferable. The sulfur dioxide is often converted to sulfuric acid in a plant adjacent to the smelter.
