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.

The Future for Flotation | E & MJ
Flotation has been a mainstay of mineral processing for the best part of a century, and the technology continues to develop. E&MJ asked some of the world’s suppliers of equipment and reagents for their insights on current and future trends.. Flotation is one of the key technologies within the mineral processing catalogue.
Depressants and dispersants - huntsman.com
Dispersing reagents are surface charge modifiers. When processing complex ores their purpose is to prevent aggregation of fine and gangue particles. The dispersant controls the charge density at the solid-liquid interface or the electrical charges of fine and ultrafine particles so they remain as discrete, stabilized particles in solution.

COPPER Copper production - svn.eeni.tbm.tudelft.nl
Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated ...
Copper Sulfide Flotation - Mineral Processing & Metallurgy
Copper Ore Grinding. Porphyry copper ores usually are medium to medium hard and require grinding to about 65 mesh to economically liberate the copper minerals from the siliceous gangue. Sometimes a regrinding circuit is advantageous on the rougher concentrate and on the scavenger concentrate.
12.3 Primary Copper Smelting
12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg) (1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting ...

Copper Mining and Extraction: Oxide Ores
The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

In some cases for example, sulphides ores of copper, zinc and lead concentration is brought by this method.In this method advantage is taken of the referential wetting of the ore by an oil.The finely ground ore is taken in a tank containing water and 1% of pine oil or terpentine oil. A strong current of air is blown through the suspension, producing a heavy froth or foam on the surface.The ...
