copper tailings separation

New approaches for extracting and recovering metals from

May 15, 2017· When bioleached aerobically at 30 °C, ∼35% of the copper was extracted from CLC tailings during the first two weeks, but after that time copper concentrations decreased alongside those of soluble iron (Fig. 2a), and the final copper concentration in the leach liquor was equivalent to 32% extraction from the tailings.

Copper extraction Wikipedia

Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings. When rich enough, native copper ore bodies may be treated to recover the contained copper via a gravity separation circuit where the density of the metal is used to liberate it from the lighter silicate minerals. Often

05 Nov Execution of further copper tailings transactions

Nov 05, 2020· The Company’s highly experienced technical and operational teams plan to construct a copper concentrator at the tailings resource to produce two separate concentrates for both the acid soluble copper oxides and the sulphide associated copper. This facility enables the Project to process copper tailings previously regarded as uneconomical.

Development of copper recovery process from flotation

Jun 15, 2018· 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 (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%).

Geotechnical Properties of Mine Tailings Journal of

The engineering properties of tailings are important for the safety evaluation and engineering design of tailing dams. In the present study, laboratory experiments were performed to investigate the geotechnical properties of four different tailings, including two iron tailings (coarse and fine) and two copper tailings (coarse and fine).

Economic Potential for reprocessing Copper Mine Tailings

A total of 81 tailings samples were analyzed using XRF, during the survey sampling. The copper grade of the tailings varied between 0.1 % and 1.7 %. Further elements of interest were iron, gold, molybdenum and zinc. This data and the tonnage of the tailings ponds was the basis to select four sites for a more detailed
