Froth flotation - Wikipedia

Froth flotation is a process for selectively separating of 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.

Mineral Comminution and Separation Systems

To achieve the goal of recovering these concentr ates, the raw ore must be reduced to fine size prior to separation. This process is called 'comminution' or 'size reduction'. Generally there are two major objectives for comminution in mineral beneficiation: The first objective of comminution is 'liberation'.

Hematite (α-Fe 2 O 3) is widely distributed in various rocks and is one of the most common and abundant iron oxide minerals in soil (Zhang, 2007).However, it cannot be used in iron and steel industry without preliminary beneficiation due to its low grade. Many researchers have investigated the separation of iron minerals from gangue minerals by froth flotation process (Luo et ...

CHAPTER 1 MINERAL DRESSING - Webs

As there is a partial separation of gauge from the ore, lesser amount of upgraded ore is to be smelted for a particular output capacity. This reduces the fuel and energy consumption per ton of metal smelted. 6. Enhancing the efficiency of unit processes: Sometimes the ore is separated into one or more valuable products and a tailing.
