Routine mineralogical analysis of copper deportments in the flotation tailings and final concentrate carried out by AMTEL (Figure 2) identified finely disseminated locking of fine-grained copper sulphides in gangue-mineral composite particles as the primary driver for copper losses from the flotation circuit, accounting for over 75% of the contained copper grade in tailings.

Copper Flotation - Elmhurst University

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 ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a ...

Filtration of Copper/Gold Tailings for Mine Backfill - BOKELA

Two BoVac Disc filters L176 are operated in a Gold/Copper Mine in Bulgaria for the filtration of flotation tailings which are used for mine backfill. The dewatered and discharged filter cake is mixed with cement and pumped back to the underground to fill the galleries.

RECOVERY OF COPPER FROM COPPER SLAG AND COPPER SLAG FLOTATION ...

slag flotation tailings are inferior in terms of leaching when compared to the slag because most of the liberated copper phases have been removed by flotation. Based on the chemical compositions of the slag and the slag flotation tailings (Table 1), it can be concluded that the copper dissolved from the slag flotation tailings mainly

Copper Tailings - Elmhurst University

Water Reclamation and Tailings. The concentrated ore, now called copper concentrate, is dewatered and dried to about 10% moisture content. It is shipped by truck to the Asarco smelter in Hayden, Arizona. (The El Paso smelter is on stand-by status). Water is recovered from the tailings in another thickener.

Improved flotation kinetics in first recycling of Melbourne and deionised waters were observed. Three recycles of mine water in the flotation process indicated a steadystate rate for copper tailings. This was not valid for Melbourne and deionised waters where flotation was inhibited successively by three waterrecycles.

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].

Development of copper recovery process from flotation ...

The total copper recovered from its ore through flotation process is about 56% [ 6, 18 ], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.20.4%) than that of lowgrade ores (0.20.3%).
