  • 60 Centuries of Copper The Flotation Process

    This explains why in order to smelt 4 million tons of new copper in 1963 nearly 400 million tons of ore had to be handled and treated in various ways. Flotation depends on the fact that the grains of some minerals and especially of metals differ in the degree to which their surfaces can

  • Copper Mining and Processing Processing of Copper Ores

    After the copper ore is crushed liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and worthless rock called gangue (pronounced gang). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue. Chemical reagents called

  • Flotation Concentration Elmhurst College

    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

  • Flotation Cells in Iron Ore Processing Froth Flotation

    Could it be a good choice for flotation of coarse and dense iron ore particles without any settlement? Froth Flotation (Sulphide Oxide) Froth Flotation air cells we can control the turbulence zone by changing the air flow but in induced air cells we have to stable the froth zone manipulating the rotor speed or other mechanical

  • What is Froth Floatation and how is it used in extraction

    Froth Floatation. This method employs a mixture of water and pine oil which is made to froth in a tank to separate sulphide ores. The differences in the wetting properties of the ore and gangue particles separate them. A mixture of water pine oil detergent and powdered ore is first taken in a tank.

  • Froth flotation

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing paper recycling and wastewater treatment industries. Historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th century.

  • Froth Floatation Process Fun Science

    Froth Floatation Process In this method powdered ore is put in a tank full of which cause the sulphide ore particles to stick with the oil and rise to the surface in the form of froth. The gangue particles being heavier remain behind at the bottom of water tank. The froth is separated and concentrated sulphide ore is obtained from it.

  • Flotation ore dressing Britannica

    Flotation is widely used to concentrate copper lead and zinc minerals which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.

  • Why is the froth flotation method only used for sulphide

    This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil. This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by the wat...
