Abstract:
This work contains the results from experimental testing on the process of oxidation copper leaching under pressure from concentrate obtained after the re-flotation process of tailings. Flotation tailings are a significant resource for recovery of copper and other useful components, since their content in tailings is approximate to the content in the primary raw materials. On the other hand, the dumped flotation tailings, under the influence of the atmosphere, pollute the surrounding land, surface waterways, as well as the groundwater, and present a serious environmental problem.
Larger global companies are involved in research related to the process of obtaining the useful components from tailings. Testing the flotation process at the site Katanga [1] was focused on valorization of copper and cobalt from tailings. In the Musselwhite Mine in Ontario, the process of flotation concentration [2,3] has confirmed that this is an effective method for reducing the content of sulphides present in tailings. The effect of sulfuric acid concentration as a leaching reagent was tested, as well as the effect of temperature, pressure, and pulp density on the degree of copper leaching. The obtained results indicate that the use of combined procedure of re-flotation tailings and copper leaching under pressure achieve a high degree of copper separation of over 98%.
