Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and le

Flotation - Mineral Processing Metallurgy

17/03/2017  The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical

bubbles in a froth created by foaming agents and air injected into the flotation cells. The copper-rich froth is skimmed off and dried to form a copper concentrate. The effective-ness of this concentrating step depends on maintaining a specific pH range so the bonding action can take place. With the recent drop in copper prices, a more effi-cient concentration process may be the key to ...

Low-Pressure Blowers and Mining: Froth Flotation and

06/07/2017  Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity (how much they are attracted to water) and is enhanced through the use of surfactants. Surfactants are chemicals that act as a wetting agent to attach to particles and increase their attractiveness to air bubbles. The first step in the flotation process involves crushing ...

"CAVITATION NANOBUBBLE ENHANCED FLOTATION

Froth flotation is a widely used, cost effective particle separation process. However, its high performance is limited to a narrow particle size range, e.g., between 50 µm and 600 µm for coal and between 10 µm and 100 µm for minerals. Outside this range, the efficiency of froth flotation decreases significantly, especially for difficult-to-float particles of weak hydrophobicity (e.g ...

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 ...
