The Unit Flotation Cell receives the discharge from the ball mill for recovery of a substantial amount of the granular silver minerals together with galena as soon as freed.

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 an appreciable amount of gold.

Flotation contact time required for the ore is one of the determining factors in calculating flotation cell capacity. If an ore is slow floating and requires twelve minute treatment time, and another ore is fast floating and requires but six minute treatment, it is evident that a machine of only half the capacity is necessary in the last instance.

Our flotation cells are cell to cell type flotation machine which always combine several sets together as roughing stage, cleaning stages, or scavenging stages. ...

The aim of this work is to develop low-concentration carbonate phosphate from the Sra Ouertane region. Indeed, the Sra Ouertane low-grade phosphate ore needs an efficient process to remove the impurities, such as carbonates, silicates as well as clay minerals, to meet the requirements of the phosphate industries. Froth flotation is considered as the prevalent …
