Hydrofoil are not so sensitive to that

Don’t get me wrong, I’m not some old person who judges huge things by relying on small ones, but if heating up my food for just 2 minutes requires so much electricity, then what’s worth talking about the huge earth’s crust in which many kilometers down are located metals with very heavy electrical and thermal conductivity. P.S. I myself was finishing my bachelor’s degree in 2019, resource extraction and similar microwave technology were also discussed then.

@sergeynikiforov1991 Well, as I see today from ordinary discussions, this topic has not even advanced, I believe that it will not advance. Now popular topics in the world are artificial intelligence and launching a rocket to Mars, no one is talking about making it easier to extract resources on earth since they are so limited.

hahaha, why are you that excited bout that?😅 of course, using old methods of extracting minerals and metals will always be cheaper than coming up with new methods. but it's probably worth giving me some time to develop this idea. perhaps in 50-70 or maybe 100 years we will see how completely all methods of processing mining will be carried out using microwave rays. but i really liked your opinion that microwave waves will use large reserves of electricity, since right at home, when you turn on microwave ovens, a transistor clicks indicating a voltage surge. i don't know how this happens on a large scale. i also thought about the fact that it takes a lot of time to heat up even a small amount of food, and the right places on the plate always heat up the food. what will it happen if we scale up such a microwave oven for a huge resource extraction site? then this option is not really promising.

You can calculate P as power number(for hydrofoil is 0.3)*rotational speed^3*diameter^5*density of fluid

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.

​@@ForuiMachineryThanks for explanation.

@@ronakcarpenter9060 You are welcome.

@@ForuiMachinerygreat thanks!

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.

Noticed that

me to!!

No because hydrofoil is slightly affected by the clearance

Yess I have the same doubt ! The density of the liquid being handled could have been a parameter to determine this ratio as well .

For liquid emulsions and foam use a sawtooth (Cowles type)

Sir what about the density of liquid? Doesn't it affect the ratio as well ?
