Flotation of smithsonite from tailing coming from a cerussite flotation circuit was investigated using Armac C and Armac T as alkyl amine acetate collectors. The results showed that the dosage of Na 2 S, collector type and dosage, collector's mixture ratio, and desliming are the main affecting parameters on the Zn grade and recovery of smithsonite flotation concentrate.

Zinc is mostly extracted from oxidized zinc and zinc sulfide minerals, and this process involves flotation as a key step. While it is easier to float the sulfide mineral, its consumption and depletion has led to an increased reliance on oxidized zinc minerals, including smithsonite. Hence, the development of efficient ways of collecting smithsonite by flotation is an important objective ...

Zinc - Wikipedia

Other source minerals for zinc include smithsonite (zinc carbonate), hemimorphite (zinc silicate), wurtzite (another zinc sulfide), and sometimes hydrozincite (basic zinc carbonate). With the exception of wurtzite, all these other minerals were formed by weathering of the primordial zinc sulfides. Identified world zinc resources total about 1.9–2.8 billion tonnes. Large deposits are in ...

Zinc processing - Ores Britannica

The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine or smithsonite (ZnCO3). The geology of zinc deposits is complex. In most cases, hydrothermal mechanisms have occurred in which aqueous solutions were forced through porous strata at high ...

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 ; 2ZnS + 3O 2 ==> 2ZnO + 2SO 2. 2ZnS(s) + 3O 2 (g) ==> 2ZnO(s) +
