smelting process for zinc ore

Zinc: smelting, producing and classification-Metalpedia

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. Secondary (recycled) zinc material, such as zinc oxide, is also processed with the zinc sulfide.

Zinc Smelting Assignment Point

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron because, in contrast, zinc has a low boiling point.

Smelting Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Cadmium isotopic fractionation in lead-zinc smelting

During the smelting process, the ε 114/110 Cd of the accumulative vapor and slag can evolve toward routes A and B, respectively . When the evaporated Cd was increasingly recovered (i.e., route A), the ε 114/110 Cd value of vapor phase tended to be consistent with zinc ore concentrate. As the Cd volatilized from zinc ore concentrates increased

Base Metal Smelting What is Metal Smelting?

Metals such as zinc, lead copper and nickel all undergo this process ("Smelting..."). Smelting is the process where "heat is used to extract metals from their ores" ("Smelting..."). There are two types of processes involved in smelting. Primary smelting "processes mine ore and concentrates" and secondary smelting process removes scrap (Mayfair,1).

Jul 15, 2014 Historically metallic zinc was one of the later metals to have as a metal. The big issue was that the burning temperature of zinc was lower than it's smelting temp making the process pretty much a no go.
