Dynamic froth stability of copper flotation tailings

Aug 01, 2018· This work fills this gap by determining the dynamic froth stability of copper flotation tailings, considering different particle size distributions and at a range of superficial gas velocities. In addition, batch flotation tests were performed for selected conditions to obtain a preliminary assessment of flotation performance.

Development of copper recovery process from flotation

Jun 15, 2018· A sample of flotation tailings obtained from Bor Mining, Serbia, was used in this study. The chemical compositions of the initial sample (flotation tailings) and feed sample (copper concentrate) were confirmed by inductively coupled plasma optical emission spectroscopy (ICP‒OES) and X‒ray fluorescence spectrometry (XRF) as shown in Table 1.The copper concentrate was first

Copper Leaching from Refractory Flotation Tailings

copper sulfide and free oxidation copper in the raw ore were recycled by flotation, but the other refractory copper oxides, mainly the combination copper oxide, were not thoroughly recycled and the majority were lost in the tailings. As is typical for flotation tailings containing silicate gangue minerals, high temperature leaching was used [12].

Coarse-particle flotation applied to copper sulfide ores

As regards of the tailings recovery application, it is seen that it is possible to recover 33% of the copper that is being lost in the rougher tailings at the stud ied plant. After classifying the tailings,the coarse fraction (>150 µm) had a grade of 0.162% Cu, and from this

Ultrasound treatment on tailings to enhance copper

Dec 01, 2016· As ore grades fall, the amount of tailings production for the same copper production is expected to rise. Flotation recovery of copper sulfide from the El Teniente plant has deteriorated in recent years, in this regard ultrasound treatment of tailings for enhanced copper recovery was evaluated in laboratory experiments.
