flotation reagents used to separate minerals

Flotation Reagents’ Types and Working Principles CNFREE

At this time, flotation reagents are used to change the nature of one of the minerals and separate them one by one. In the case of lead-zinc separation, the “zinc-inhibited and lead-collected” program is usually adopted. That is to say, an inhibitor that inhibits zinc

Flotation Used for Separate Fine Minerals-xinhai

In the process of flotation, the same kind of mineral or different kind of mineral can be used as the carrier according to the actual situation. For example, in the flotation of fine gold, pyrite can be used as the flotation carrier of fine gold. 06: Agglomeration flotation method was adopted.

Flotation Used for Separate Fine Minerals-xinhai

•02Fine particle minerals are easier to absorb flotation reagents, but they have a bad selective absorption and a large surface solubility. So it increases the particles that difficult to separate. •03The micro-grained minerals are small in size and are less likely to collide with flotation bubbles. They has a small quality so it is hard to overcome the resistance from the hydration shell ...

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

“Flotation reagent selection is paramount and test work is necessary to ensure the optimum reagent suite is utilised. If the ore contains a low amount of iron sulphides, xanthate collectors are often suitable to float copper sulphideminerals. If native gold is present, dithiophosphates can be used which are less selective to iron sulphides.
