copper ore floatation machine

The hydrophobic nature of the copper particles due to the hydrophobic properties of their surface or by flotation agent role, aggregation occurs in the liquid - gas or water - oil interface.

Currently the most widely used is the froth flotation method. Copper ore by crushing and grinding various minerals dissociated into the monomer particles, and particle size of the flotation process.

Adding a variety of flotation reagents to the slurry after grinding and mixing harmonic, so the role of the mineral particles, in order to expand the the flotability difference between the different mineral grains. Good tune pulp into the flotation tank, stirring inflation.

Copper particles in the slurry bubble contact, collision, Flotability good ore adhesion of particles to selectively carry air bubbles and rise to become a gas - liquid - solid phase composition of the mineralized foam layer by mechanical scraping or overflow from the slurry surface, and then dehydrated, dried into the concentrate product. It does not float gangue mineral particles with the slurry from the bottom of the flotation cells is discharged as tailings product.

Useless copper minerals floating particles, useful mineral particles remain in the pulp, known as the anti-flotation, floating quartz from iron ore.

The froth flotation is suitable for sorting 0.5mm to 5μm mineral particles, depending on the specific grain limit, as the minerals. Selected particle size less than 5μm when using a special flotation method.

Such as flocculation - flotation flocculant to make fine-grained useful mineral flocculation into larger particles, prolapse of the gangue of fine mud and then float to coarse-grained gangue.

The carrier flotation of particle size suitable for the flotation of mineral particles as the carrier, so that the fine mineral particles adhere to the carrier surface and subsequently float separation.

The flotation of oil agglomeration flotation and emulsion flotation of fine ore particles reunion as well as with the oil; and the use of high-temperature chemical reaction of metallic minerals in the ore into metal after flotation segregation flotation.

Foam flotation in aqueous solution of metal ions using chemical precipitation or ion exchange resin, and then flotation of precipitate or resin particles.
