Together we can build an ideal Plants. The most important thing is harmony!

At work I have a lot of contact with the Plants. Very sad to see many of the Plants.  For example, a new modern Plant of known company that uses the best technology, the best equipment, costly reagents. But eventually the Plant's tails must be processed again. Such large losses of valuable minerals. And we need to put another Plant for processing tails.

Can they just design a Plant correctly? Can they avoid new additional costs? 

The problem is that almost all mining projects are typical. They do not take into account the peculiarities of local ores or poorly consider them.

I see how it is possible to correct these shortcomings, but nobody wants to do that, because it is expensive and difficult for already existing Plants.

New Plant - a godsend for me. 

Because at the design stage, you can take into account these errors and make your Plant as necessary, almost without loss.

Make it so that it was an ideal Plant! 
Not necessarily put all the most expensive, not necessary to use very expensive reagents, it is welcome, but it is not the most important thing.

The most important thing is harmony!

 The most important thing - it is how to use all available technology and equipment, how to tune it. The approach has to be very flexible. It is necessary to use different technologies in one deposit. Each ore requires a different approach.

I know very well how to separate minerals from each other. I know how to do it cheaply.

I have a lot of intelligent products and solutions (more). I also have a lot of other ideas that are not yet represented on my web site.
I can make my intellectual property as my contribution to your project. And it will give to the company a competitive advantage.
Patents for my decisions can be obtained now. After the patenting of my decisions, they will have to be much more expensive (x10 - this is the minimum). And I will give them to you in their prices of my web site. So it is extremely profitable transaction.

Besides, I can advise you on every occasion, I can help you at each stage, matters related to the separation of minerals. Intermediaries are not needed.

If I taked up the case, then I bring it to the end.

I am a scientist and a mining engineer, a professional in my field. I am not afraid of a lot of work. I'm a workaholic. In life, there are very few things that interested to me, except the concentration of minerals.  I can replace a Research Institute of ore processing, if this is necessary.
I can do almost everything myself: theoretical analysis, all laboratory tests, to calculate the project at the necessary power to choose the equipment, etc. I can also do any current changes and optimization. All that I can do alone or with my husband. He can help with modeling of process.

This means that will disappear (or seriously decrease) the need for funding of scientific research in the concentration of minerals, with the participation of major design organizations.

Together we can build an ideal Plant (or Plants).

I do not undertake projects without my independent assessment. If you did not order a quick assessment from me here
The express evaluation of the ore deposit
Assessing Investment Risks in Mining
and you did not pay the prepayment to my personal account, then my participation in the project is impossible. If you see my name or my signature in the list of performers or in other documents, in this case, do not believe it! It’s a fake copy! Send me the information about such case!

GENIUS vs. UNIVERSITY


You send me many letters asking me to write my business plan. It is right that you are interested in my opinion. I worked in different universities of the world. I communicate a lot online with different people.

I can share my independent opinion about mining in the world. Everywhere is the same. They promise to do this work and go to the laboratory to do experiments. Next on luck. It turns out or not. 

There is no laboratory in the world has enough equipment and specialists to create new generation technologies. Problems are growing. Traditional types of ores are running out but for new ores there is no technology.

I did a little calculation. How much money is needed to create a modest modern ore benefication laboratory.
1. Buildings and facilities – 20 million dollars
2. Equipment and apparatus – 15 million dollars
3. Monthly expenses are more than 15-20 million dollars per month.

At full load, this laboratory and design organization can perform work for a maximum of 2-3 million dollars per month. This whole company of specialists from around the world will be able to perform work only in a close-knit team: because each of them knows only his own problem and does not control the whole situation in the complex.

This means that every month you lose 18-12 million dollars per month (216-144 million dollars a year). You also spent another 35 million on equipment and building. Also You have to spend several million on staff training.

Let’s say that you went the traditional way. You invested hundreds of billions of dollars (for 50-100 years). You have trained hundreds of new specialists, opened new research institutes and laboratories, and issued hundreds of scientific grants. And so, 50-100 years passed, but a miracle did not happen. If you have not yet done this, then stop, and do nothing.

Universities understand that they have no such opportunities, but they really want the money. They create a fairy tale for investors on paper. Next to the sign that this is a student’s educational laboratory of ore beneficiation, new ones will appear: Innovation Center, Technology Center, Technology Certification Center, Certification Center of raw materials (ore, waste), Center for complex processing of raw materials, Laboratory for waste processing and so on.

If earlier it was a backward laboratory with old non-working equipment measuring 100 square meters, now, according to documents, this is a certified scientific center measuring 200-600 square meters and with the latest stunning equipment worth millions dollars.

They enter into their documents famous people who do not even know it. I learned many times that someone enrolled me in my project or scientific school without my consent and permission.

They draw up the necessary documents and begin to search for the simpleton. However, they have no idea what they will do.

I know many such examples. If a researcher can just “eat money” for years without getting the expected final result, then he will do so (Murphy’s Law). The increase in funding for research will only exacerbate this situation.

I suggest that you bypass the path of traditional development.

I considered the costs and did not create a laboratory. I created “PETROVSKY´S MATRIX”.
For many years I have been working on creating a “Mineral Benefication Information System”. I create it with my own money and am the only copyright holder.

This system you need. I don’t need it.

I can create 5 competing technologies for any ore without any information system. It is very difficult and only I can do it. In fact, “Mineral Benefication Information System” will be my only competitor.

You need my “Mineral Benefication Information System” and “Petrovsky’s Matrix”.

No need to teach anyone. For this, you will need centuries of hard work and the abandonment of all your stereotypes, theories and delusions. I think that for you it is almost impossible in the near future.

You need just to create a my smart system and let it work.

You do not need hundreds of specialists in the field of mining, but only a few people to interact with the expert system”Mineral Benefication Information System”. An independent expert system will describe the real situation (only if it is correctly taught) and will give you the accurate way of solving the problem.

Therefore, if we are talking about relatively small investments (about USD 10-20 millions), then I can recommend you to invest in me, this is the most reliable investment.
So, my business plan is an investment in me and under my name. Then we decide what is best for you, we can determine in detail the larger investments (under USD 1 billion and more).


You choose.

Sincerely, Ph.D. Natalia Petrovskaya

“Progressive flotation machines and auxiliary equipment of the world” and “Mineral Benefication Information System” By Ph.D. Natalia Petrovskaya

Dear Colleagues!

I am pleased to inform you that I continue to create the “Mineral Benefication Information System”. You can read about the system here. More

I created a classification of flotation machines.
CLASSIFICATION OF FLOTATION MACHINES.png

At this stage, I continue to collect information on flotation machines and auxiliary flotation equipment.

This information will be used to create algorithms and programs within the “Mineral Benefication Information System” for the selection and calculation of equipment for flotation.

I create “Mineral Benefication Information System” by the following criteria:
1. The design and principle of operation of the flotation machine
2. What physical processes occur in the flotation machine of this type.
3. Types of aeration used in this machine
4. For which types of flotation, you can use a flotation machine of this type. Expansion of the scope of activities.
5. Improving flotation control
6. Advantages
7. Disadvantages
8. Prospects for modernization and improvement
9. Recommended reagent modes and schemes
10. Methods for calculating flotation machines
11. Other.
This data does not exist anywhere. I will analyze every machine myself.

Often, manufacturers of flotation machines themselves do not know all the advantages of their machines, which limits the scope of their use.

To get into my “Mineral Benefication Information System”, you must send the information you want to announce (or links to sites). I consider all flotation equipment: current, outdated, patents, models, and so on. When I receive your information you will see it on my websites and blogs. More

In order for your brand to enter my “Mineral Benefication Information System” and I process it at the proper level with benefit for you and for the plants, a voluntary contribution of US $ 10,000 for the first model and $ 5.000 for each subsequent one is paid. For laboratory flotation machines, the voluntary contribution is $3,000. The first 3 companies or persons who pay before November 15, 2018 will receive a 50% discount on the first model and 25% if they pay before December 1, 2018.

Today you will receive information on my criteria, which
1. Will enter the “Mineral Benefication Information System” without fail
2. Will be used in my new book “Progressive flotation machines and auxiliary equipment of the world” without fail
3. Will be published on all my websites and blogs.
4. You will have the opinion of a specialist how to expand the scope of activities and modernize the machine.
5. You can also use it at your discretion.
In addition, I have a special offer for manufacturers of laboratory flotation machines.
You can also participate in the publication of my book “Fundamentals of the Theory of Flotation. 2nd Edition.”
