copper flotation plant

copper processing plant, copper flotation plant, copper extraction plant

Introduction

Flotation is the common copper processing technology, which can be used for sulfide ore and oxide ore. The copper flotation plant usually includes following steps: crushing and screening, stage grinding and flotation, thickening and dewatering, and copper concentrates recovery.

Copper Processing Plant

One-stage Grinding+Flotation

Application

It is suitable for smooth and flat copper ores in coarse and evenly embedding granularity. Which is loosely combined with gangue minerals.

Main technology conditions

  • -200 mesh 50%~60% in common, basic monomer dissociation for copper minerals

    Grinding Fineness
  • Ideal flotation indexes can be required through coarse flotation, scvanging and 1-3 concentrating.

    Flotation Technology

Advantages

This flow is simple and with low cost. It is widely used in small and middle copper processing plant.

One-stage Grinding+Coarse Flotation Concentrates Regrinding Flow

Application

It is suitable for single bornite sulfide ore or copper-molybdenum ore.

Main technology conditions

  • Through one-stage grinding, the fineness reaches -200 mesh 40%~70%. After flotation, the coarse concentrates are regrinded. The regrinding fineness is according to the monomer dissociation condition.

    Grinding fineness
  • Through coarse flotation and scvanging, an amount of tailings are removed.

    Flotation technology

Characteristics

If the grade of raw ore is low with large capacity, ideal economy efficiency can be acquired. Because of coarse concentrats regrinding, the granularity is fine. Copper minerals, gangue minerals and pyrites can be dissociated monomer. The flotation concentrates has high quality.

Two-stage grinding + two-stage(one-stage) flotation process

Application

It is suitable for uneven thickness copper ore. To reach most copper mineral monomer dissociation, the grinding fineness is thinner. Under this condition, two-stage grinding is applied.

Main technology conditions

  • Minerals under 200 mesh is about 80% or more. (To dissociate most of the mineral monomers)

    Grinding fineness
  • After the first stage coarse grinding, part of coarse copper minerals is recovered in flotation. The grade of this part of copper concentrates has high grade, which can enter final concentrating or be as the final concentrates with the comcentrates after flotation.

    Flotation technology

Advantages

The two-stage grinding has better effects in grinding efficiency and predicting overgrinding than one-stage fine grinding. Therefore, it is commonly used in middle and large copper processing plant.
