how copper ore is concentrated by froth flotation process in korea

The copper minerals and waste rock are separated at the mill using froth flotation The copper ore slurry from the grinding mills is mixed with milk of lime simply water and groundup limestone to give a basic pH pine oil yes it comes from trees a byproduct of paper mills to make bubbles an alcohol to strengthen the bubbles and a collector chemical called potassium amyl xanthate or the potassium

The most effective method of isolating the Cu minerals is froth flotation This process causes the Cu minerals to become selectively attached to air bubbles rising through a slurry of finely ground ore in water Fig 14 Selectivity of flotation is created by using reagents which make Cu minerals water repellent while leaving waste minerals wetted

The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants Flotation has now become the most widely used process for extracting many minerals from their ores

Jul 04 2017 · Oxidic ore can be concentrated using flotation or if it has a low acid demand it may be economic to acid heap leach the stockpile The recovery of these copper minerals by flotation or

Frothing also known as froth flotation is the process of selectively separating hydrophobic valuable minerals from hydrophilic waste gangue In its simplest form froth flotation is a method whereby minerals can be “skimmed” from the surface of “slurry” that is “foamed” with the assistance of specific chemicals water and air bubbles

The crushed ore is grinded in ball mills to −74 μm size The ore is processed by froth flotation comprising rougher and scavenger cells The common reagents for copper ore flotation are xanthates as collector pine oil as frother sodium cyanide as depressant and lime to maintain slurry alkalinity

The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals The ore is then wet suspended in a slurry and mixed with xanthates or other reagents which render the

Sep 26 2019 · Sulfide Ores Virtually all sulfidetype copper ores including chalcocite Cu 2 S chalcopyrite CuFeS 2 and covellite CuS are treated by crushing the ore to a fine powder it is concentrated by froth flotation which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic
