Common Copper Tailings Reprocessing Methods - Xinhai

2020-11-16  02 2.Copper tailings reprocessing method (1)Vulcanization flotation of copper tailings. The essence of vulcanization flotation is to sulfide the ground copper oxide pulp with sulfide and flotation with xanthate collector. Copper oxide is in sodium sulfide solution, which adsorbs HS- and S2-. It forms a covering layer of copper sulfide.

Copper Leaching from Refractory Flotation Tailings

2018-4-18  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].

Separation of chalcopyrite and pyrite from a copper ...

2018-9-1  For the copper tailings, the objective of the flotation is to detach the copper minerals from other sulfide minerals (usually pyrite) and the gangue minerals. The main difficulty lies in the depression of pyrite, which conventionally proceeds in high pH conditions by using large amounts of lime (CaO).

REPROCESSING OF THE OLD FLOTATION TAILINGS

2009-3-21  Flotation tailings reprocessing consisted of acid leaching followed by re-flotation of the leach residue. Leaching of the tailings resulted in leach liquors containing Cu2+ ions from 50 to 580 ppm. The average copper removal degree in the leaching stage was 70%.

RECOVERY OF COPPER FROM COPPER SLAG AND

2014-9-8  Abstract: Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings.
