Chemistry bloggg :D: Extraction of Zn from zincblende

Sep 01, 2021Zinc Blende, also known as Sphalerite (zinc sulfate), is a major ore of zinc, a mineral. It can be found in many locations worldwide. Zinc is often extracted from sphalerite as it contains 40-50% of zinc. Zinc metal is extracted from sphalerite using extractive metallurgy. Froth flotation is a process for separating minerals from gangue by

Zinc Chemical Element Properties

Dec 02, 2021The most common Zn ore is sphalerite (Zn blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. It is refined by froth flotation of the ore, roasting, and final extraction using electricity. The element was probably named by the alchemist Paracelsus after the German word Zinke (prong, tooth).

How zinc is made

2 Zinc can be produced by a process called froth flotation, which is also used for reduction of copper and lead ores. This process involves grinding the zinc ore to a fine powder, mixing it with water, pine oil, and flotation chemicals, and then agitating the mixture to float the zinc to the surface.

The sulfurisation-flotation process was unsuccessful when initially applied to the oxidised Pb-Zn ore in Lanping County of Yunnan Province China. A comprehensive mineralogical study indicates that the problem is caused by the soluble salt gypsum in the Lanping oxidised ore, which produces a large amount of Ca2+ cations. The Ca2+ cations react with S2- anions (from sodium sulfide) in preference
