extraction of zinc from its ore containing galena

extraction of lead zinc from galena -

Empire City was annexed into Galena as its Fifth Ward in 1910. By that time, Galena boasted three banks, three newspapers, and an opera house. Though its primary lead and zinc mining and smelting remained its principal industries, there were also foundries, stamping works, grain elevators, a novelty works, and a broom factory.

Extraction of Zinc - Introduction, Mining, Procedure,

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
