Zinc Ore - an overview ScienceDirect Topics

Gold recovery from copper– zinc ores is usually higher than that obtained from either a lead–zinc or copper–lead–zinc ore. This is attributed to two main factors. When selecting a reagent scheme for treatment of copper–zinc ores, there are more choices than for the other ore types, which can lead to the selection of a reagent scheme which is more favourable for gold flotation.

Evaluation of processing options for the treatment of zinc ...

For sulphide ores, a concentrate containing zinc sulphide as sphalerite or marmatite is usually produced. The standard process for zinc sulphide concentrate treatment is the roast-leach-electrowinning (RLE) process. This process is highly efficient at converting the zinc in concentrate to SHG zinc metal by roasting to zinc oxide, acid leaching and

Zinc smelting - Wikipedia

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. At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific measures are taken to prevent it. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphale

Zinc - Simple English Wikipedia, the free encyclopedia

The zinc sulfide is concentrated by flotation. There is a detergent that collects the zinc sulfide. The impurities sink to the bottom and are removed. Then the zinc sulfide is heated in air to make zinc oxide and sulfur dioxide. 2 ZnS + 3 O 2 → 2 ZnO + 2 SO 2. The sulfur dioxide is oxidized to sulfur trioxide. 2 SO 2 + O 2 → 2 SO 3
