zinc sulfide oxidizing:

22.3: Oxidizing and Reducing Agents - Chemistry LibreTexts

The zinc causes the sulfur to gain electrons and become reduced and so the zinc is called the reducing agent. The oxidizing agent is a substance that causes oxidation by accepting electrons. The reducing agent is a substance that causes reduction by losing electrons.

Zinc Sulfide - an overview ScienceDirect Topics

Lead concentrates are usually accompanied by zinc in the form of zinc sulfide. During roasting, the zinc sulfide turns into zinc oxide. During roasting, the zinc sulfide turns into zinc oxide. Especially in the shaft furnace process for lead production, the reduction rate is set in such a way that lead is reduced while zinc stays as oxide and mainly ends up in the slag.

Zinc Sulfides - an overview ScienceDirect Topics

Before smelting, zinc sulfide is usually concentrated by a float and sink method. The zinc sulfide is then roasted to form zinc oxide, followed by reduction with carbon and/or carbon monoxide. Zinc metal is distilled off. About half the zinc produced is used as a coating metal. The most common method of coating is hot-dip galvanizing.

Zinc Sulfide - espimetals

Unusual Fire Explosion Hazards: Zinc sulfide decomposes at temperatures greater than 400 o C in air and/or in oxidizing atmospheres. Zinc sulfide produces zinc and sulfur fumes at temperatures greater than 900 o C in inert atmospheres. Contact with strong acids may liberate hydrogen sulfide which may form explosive mixtures in air.

Compounds of zinc - Wikipedia

Zinc oxide, ZnO, is the most important manufactured compound of zinc, with a wide variety of uses. It crystallizes with the Wurtzite structure. It is amphoteric, dissolving in acids to give the aqueous Zn 2+ ion and in alkali to give the zincate (a.k.a. tetrahydroxozincate) ion, [Zn(OH) 4] 2−.Zinc hydroxide, Zn(OH) 2 is also amphoteric. Zinc sulfide, ZnS, crystallizes in two closely related ...
