Dr Erin, does Sepro has any application of the microwave technology for the industrial leaching process of the mineral concentrates? Thx
What is the size that could be treated or processed with the Microwave technology? How the sorting of the material will be done is the material is fine? Thx for the explanation.
Good to mix it up. Not all gold settles umder the same conditions. I'm suprized this wasn't done sooner. Look at very old drawings of gold sluices, they had sections that became much wider and then narrower. Same concept which is to vary the settling physics.
Distances of impellers from bottom must be considered
"Fluidization water" is talked about on the Knelson at 6:08 in ua-cam.com/video/awSrKnW6EIs/v-deo.html BUT they are not used in this upgrade at 7:15? They are tiny water jets in the Knelson channels, pretty much, yes?
I have been living alone for five years now and this is the fifth year since I stopped using microwave ovens. It may sound stupid, but as soon as I saw how much money I had to pay for electricity, I immediately decided to abandon this technique.
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.
[IMHO] I have very little faith that the idea is in any way capable of long life in the field of metal processing. I'm not saying that Im an expert, ngl, but it really looks difficult and expensive. Usage of microwaves, especially for heating metal, will require a lot of electricity. Also, conventional installations such as a magnetron will always be inferior to conventional methods that we have from the industrial past of Great Britain, thats fr. Think about it, people of that time were only exposed to the danger of being burned by molten metal, while when using this technology. There would still be a danger of injury from microwavess. Its not for nothing that in microwave ovens the waves themselves can only propagate inside their insulated box. imagine if these waves fly at us with enormous energy ready to burn our nervous system and leave burns of various degrees. I think that this technology should not go widely into the industry of mining or metal ore processing, but only remain for Wi-Fi, communications, and heating our food for lunch
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.
Could you explain how did you get the power draw? Speed x Diameter, ejm. 73mm x 1070 rpm = 3.71 W ?
That's a fascinating concept
I think there is a mistake in 0:32 second : The first tank's impeller runs at 1070 RPM, not 73RPM
I have been looking for a dealer to aquire a icon 150 but i havent had any luck. Ive also been trying to find someone to give me a demo on ut also with no luck. Can you give any names up ?
when you say reagents do you mean collectors? can you please explain more? thank you
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.
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.
No explanation about the reagent at all
That was not all gold. That was fine dust and gold
Can you speak spanish?
thanks for the subtitles
very interesting, does this concept also apply to machines that only process powder?
I realize there are many variables in mixing, namely here you're using a viscous parent material. But does this video contradict your earlier video here?: ua-cam.com/video/nuWAxDK-xeQ/v-deo.htmlfeature=shared
There is a large impeller spacing from reactor bottom..

Flotation vs leaching? help...!
Why are they placed with different distance to the floor? I mean, if you shuv number 1 down at the same level as number 4, wouldnt that affect the results dramatically?
what is DT ratio?
I think: diameter of the impeller / diameter of tank and its also nearness to the bottom
Thank you for very useful video! But what's about liquid emulsions? Or about solid particles that are less dense, than water medium?
Thí nghiệm này sai, khoảng cách từ cánh khuấy tới đáy bể phải giống nhau thì chúng ta mới có thể so sánh. Ở bình thứ 3 và 4, khoảng cách là quá xa. Trong các thiết kế bồn chuyên nghiệp, tỉ lệ là 0.3. Với tỉ lệ 0.4 chúng ta sẽ phải chọn Motor gấp 5 lần công suất.
Sir what about the density of liquid? Doesn't it affect the ratio as well ?
I was a sole distributor for icon in North east Africa, mainly in Sudan, icon is the best product for small artisanal, I personally recommend every small miners to use icon

Hi, Why do diaphragm pumps need air compressors. They can be operated by motors right?
Hi, I am studying beadmill process. Would you mind if I ask a few questions? What is the dispercent that you use in the tank? What is the density of the dispercent? Thank you for your helps. What is the mills inside the thank?
Very simple but very informational video. Thanks a lot! P.S. But what if I stir an emulsion of oil-soluble liquid (like styrene), whose density is lower than water and it tends to flow up? Do i have to set impeller on the same height?
Great video
She is beautiful!!
Yes, I am in love. The knowing smirk at the end making a summise summary video for all the people that searched "what happens when you microwave a rock" ? Im simping for science.
What kind of suspensions do you use?
I'm sure the liquid is just water and the particles are plastic only slightly heavier than water. For a similar demonstration, I bought plastic pearls that are sold in toy shops.
What kind of suspensions do you use?
Thank you for being honest
Great quick video! Thank you. Do you have another video on why down pumping works better with theoretical explanations?
