As can be seen from Fig. 1, the Cu recovery from the flotation of the two ores was similar at different pH values, but the Cu concentrate grade was different.The difference in Cu concentrate grade became greater as pH increased from 9.0 to 10.5 and then to 11.5. In the case of 5 % pyrite feed grade, the Cu concentrate grade was 10.3 % …
Recovery of pyrite from copper tailings by flotation
1. Introduction. The concentration of sulfide copper minerals by means of flotation generates large volumes of tailings. It is estimated that one hundred twenty-five tons of tailings are generated per one ton of produced copper, and its generation is on a continuous rise because of the decrease of the copper grades [1].On the one hand, the …

Copper Ion Recovery from Mine Water by Ion Flotation
Solutions containing copper ions are produced at copper mines due to its dissolution from ores and dumps. It is important to recover these ions to prevent this toxic element from entering the environment and because it could be economical. We investigated the use of ion flotation for extracting Cu ions from diluted mine water from …
The Challenges and Prospects of Recovering Fine Copper …
Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

The key to successful flotation plant design, production planning and mine/mill optimisation is a solid understanding of the resource to be processed. As advocated by the authors of this paper, the main components of geometallurgical modelling of an orebody and its associated flotation plant are:
Processing Gold Ore by Flotation
APPLICATION OF FLOTATION TO GOLD ORE. A flotation plant is being erected at the Falcon mine, Rhodesia, to treat ore containing gold and copper. With the exception of the Mt. Morgan, the Etheridge, and the Great Fitzroy mines, Queensland, I have not heard of the flotation process being used successfully to treat ore containing …

Selective Process Route to Recover Magnetite from
[3]. It is known that the majority of copper mines generate a large quantity of tailings after its concentration [1, 4–10]. For example, a large part of copper mines in China are con-sidered low-quality mine, which generates a large amount of copper tailings during the copper mineral separation process [2, 5, 7].
Froth Flotation Process
"The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories …
