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.

To Float or Sink: A Brief History of Flotation Milling

flotation process began in the nineteenth century, but flotation is considered the most important devel­ opment of the twentieth-century mining and milling industry. Flotation Flotation is an innovative processing method for separating valuable minerals locked in waste rock. It abandons basic principles of ore treatment by gravity

Flotation Oils for Froth Flotation ArrMaz

Flotation oils act as co-collectors, extending the collector’s ability to float the desired mineral. They provide strength to the hydrophobic layer. The amount and type of flotation oil used can directly impact the nature of the froth, and thus can control the strength and selectivity of the froth zone.

Separating Minerals by Floatation

a series of floatation cells that separate the desired mineral from other materials. Air injected into the floatation cells, along with foaming agents, creates a bubbly froth. An added chemical called a collector acts on the lighter mineral, causing it to attach to bubbles and rise to or near the surface. The float

Flotation taking its coarse

Coarse flotation can also improve the recovery if suitable collectors are used. Henrik , mining R&D manager at Nouryon, says: "When applying coarse flotation, a smaller percentage of the ore will be finely ground and lost during flotation." Another significant benefit of coarse flotation

Mining Industry Copper Sulfide Ore and Flotation Process

1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

The foundation of good flotation Mining Magazine

Many of the high-quality deposits are already mined out. Flotation appears to be the most economic way to process lower quality minerals, and successful flotation is linked to being able to economically liberate the impurities from the mineral, then design a flow sheet and reagent system to float the impurities away.
