Been looking for a good explanation of this process to share with some folks - found several terrible examples that featured some fundamental misconceptions as to how the process works. Finally found someone who knows their stuff!
Flotation reagents are chemical agents used in the flotation beneficiation process to increase the affinity between valuable minerals and bubbles, thereby achieving the flotation separation of the ore. Here are some common flotation reagents: Collectors: Used to increase the affinity between valuable minerals and bubbles, allowing them to float to the surface. Common collectors include xanthates, carbon disulfide, petroleum sulfonates, etc. Frothers: Used to generate stable foam and promote the attachment of valuable mineral particles to the bubbles. Common frothers include alcohols, xanthate alcohols, methyl isobutyl carbinol, etc. Modifiers: Used to adjust the surface properties of the ore, thereby altering the flotation behavior of minerals. Common modifiers include pH regulators, carbonates, oxidants, and reducers. Depressants: Used to inhibit the flotation of certain minerals in order to achieve more effective separation of valuable minerals. Common depressants include iron oxides, iron sulfides, cyanides, etc. Activators: Used to activate the flotation performance of certain minerals, making them more easily captured by bubbles. Common activators include copper sulfides, iron sulfides, silicates, etc. It is important to note that the specific selection of flotation reagents depends on the type of ore, its chemical composition, and the flotation objectives. In practical applications, the choice and optimization of reagents are based on the results of beneficiation experiments and experience.
it is crucial to conduct beneficiation experiments first in order to determine the optimal process flow, reagent selection, and various data parameters before commencing the large-scale mining production.

That's a fascinating concept
wut reagnts u using? 🤔
when you say reagents do you mean collectors? can you please explain more? thank you

@@ForuiMachineryThanks for explanation.
@@ronakcarpenter9060 You are welcome.
How can this process be achieved in large scale, i have a ore sample of 50000 ppm copper and 12ppm gold (300k tonne of ore)
it is crucial to conduct beneficiation experiments first in order to determine the optimal process flow, reagent selection, and various data parameters before commencing the large-scale mining production.
I want to eat the froth
No explanation about the reagent at all
