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.

Copper Flotation - Mineral Processing Metallurgy

After the rougher flotation concentrate is reground it is cleaned twice in additional “Free-Flow” Flotation Machines with the recleaned concentrate going to final concentrate filtration or, as the metallurgy dictates, to a copper-moly separation circuit. The tailings or middlings from the flotation cleaning circuit can either go to a cleaner – scavenger circuit as shown on the flowsheet or can be returned to the original rougher flotation

15-06-2018  Therefore, this research aims to develop a copper recovery process from flotation tailings using high‒pressure leaching (HPL) followed by solvent extraction. Over 94.4% copper was dissolved from the sample (CuFeS2 as main copper mineral) by HPL in a H2O media in the presence of pyrite, whereas the iron was co‒dissolved with copper according to an equation given as CCu = 38.40 × CFe.

The commercially available solution uses fluidisation to effectively float sulphide particles up to 700 microns, upping the flotation threshold. The HydroFloat has already been used to scavenge sulphide tails and allow operations like Newcrest’s Cadia copper-gold mine in New South Wales, Australia, to coarsen its grind size, according to Eriez.
