1. Introduction. With the over-exploitation of copper sulfide ore, it is of necessity to utilize and develop the copper oxide ore with low grade [1].As one of the typical copper-rich oxide minerals, the development and utilization of malachite have attracted more attention [2].Quartz is a main gangue mineral, which co-exists with malachite …

Fluorine (F) enrichment originating from natural sources is difficult to remove using chemical washing methods due to the large chemical-resistant residual fraction. This study evaluates the feasibility of using a froth-flotation separation method to remediate soil with a high F concentration caused by mica weathering, and it investigates the optimal …

The flotation separation of Cu-Fe sulfide minerals at low alkalinity can be achieved using selective depressants. In the flotation system of Cu-Fe sulfide minerals, depressants usually preferentially interact with the pyrite surface to render the mineral surface hydrophilic and hinder the adsorption of the collector. This review summarizes …

Finally, a comparison between conventional flotation and nanobubble-assisted flotation (utilizing bulk nanobubbles, surface nanobubbles, and micro-nanobubbles) was conducted. Remarkably, micro-nanobubble flotation yielded the most promising results, with the lowest loss-on-ignition in flotation tailings (3.15%) and the …

Froth flotation is a separation method that changes the surface chemistry of desired minerals, rendering them hydrophobic which allows the desired minerals to attach to air bubbles and float to the surface of the water, forming a froth. Collectors are the primary chemical added into the system to aid in flotation.

In this study, OBHA was used as collector for the flotation separation of fluorite and calcite. Under a natural slurry pH environment, the recovery of fluorite reached 80 % while calcite recovery was less than 5 % with 3 × 10 −4 mol/L OBHA. The flotation separation of fluorite from calcite can be achieved without the addition of depressants.
