### Gravity Concentration - an overview ScienceDirect Topics

Gravity concentration, ... An example is the zinc–lead–silver deposit at McArthur River, in Australia. Discovered in 1955, it is one of the world’s largest zinc–lead deposits, but for 35 years it resisted attempts to find an economic processing route due to the very fine grained texture of the ore.

### 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 ...
