Assessment of water quality effects on flotation of copper ...

Oct 15, 2014  For each flotation test, one kg of the crushed ore has been subjected to wet grinding in ball mill for obtaining granulometry of d 80 of 74 μm and flotation pulp with specific gravity of 1200 g/L. The ore has been initially subjected to talc pre-flotation during 3 min followed by copper–cobalt bulk rougher for 30 min.The talc pre-flotation has been carried out with 200 g/t sodium silicate ...

Assessment of water quality effects on flotation of copper ...

Thiosulphate presence depending on concentration promotes or hinders cobalt and copper flotation. Abstract Results from lab scale flotation show that when process water was re-used copper and cobalt recovery from an oxidized ore decreased respectively with 25% and 30% at the rougher stage bringing lower grade concentrate as well.

Copper extraction - Wikipedia

The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

Froth Flotation Process - Mineral Processing Metallurgy

Jan 20, 2021  The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
