"Mineral",the closed joint-stock society (the scientific and technical co-operative "Mineral" until 1992), was founded in February 1989 on the basis of the staff of the scientific institutions, which are the Uralmechanobr and the Unipromed, and other learned bodies, such as the firms "Uralenergotsvetmet" and the Sverdlovsk branch of "Patis", and also one of the regional medical institution. The firm is currently engaged in scientific and technological, construction and assembly activities, as well as medical ones

THE MINERALURGICAL EPELMAN'S LABORATORY

It includes both the department, which is occupied with scientific research, experimental and designing, starting-up and setting-up activities, and the independently developing patent and license department and trade mark department. The laboratory has already patented 19 proper inventions and published 39 articles of scientific and technical subject matter.
The field of scientific interests: flotation technologies of ore dressing and purification of water with fat and oil content.
The main scientific results:

1. of the new the system of the information prospecting generation technical objects was created, that significantly cuts the costs and shortens the duration of the technological and experimental design
While carrying out scientific and technical researches with the purpose of creation the new-generation technical object, the first step is to find its analogues in world-wide sources of information. Then analogues should be compared to the creating technical object in order to clarify whether they refer to the new-generation technologies or not.
In case an analogue of this object already exists, the search for the new information in order to form the most favourable design on the future engineering of the object begins. No difference whether this object is in its initial engineering stage or not. Tens or even hundreds of suitable designs (more often 100 or 200) are picked out of the whole patent and other scientific and technical data array, which includes thousands of designs on the base of the ICR (International Classification of Researches), UDC (Universal Decimal Classification), State Standards, Standards for Design Work and etc. Only 10 up to 100 designs are normally chosen on the criterion of functional uniformity to the creating object. They are classified according to their purposes and facilities to achieve these purposes. The result of the expert research is only 3 up to 10 designs are left. The next step is giving a design a proper appreciation calculating the possible economic effect or using a certain analytical method, e.g. on the base of the universal identifier.
When the most favourable design is found, the creating object and its components are investigated according to this design, which is to cut the costs and shorten the duration of the technological and experimental design of the engineering object.

2. the problem of ore intervolumetric blending before the process of dressing was brought forth and the technology of ore intervolumetric blending beyond the bounds of the inrtavolumetric one was created
Traditional ore blending before the dressing process is limited by the area of the blending yard or by the capacity of the blending installation and can be referred to the so-called intravolumetric ore blending. The effective system to mine ore selectively is required in order to guarantee the intervolumetric ore blending. The annual correlation analysis of extraction-content relation for the metals concerning their placement in the areas of ore deposits makes it true to live.

3. The magnet flotation fundamentals were put laid
The use of the contrast range of the paramagnetic mineral properties leads to the improvement of the selection during the flotation process. E.g.: In case the magnetic force acts directly on the halcopyrite particles there is a possibility not only of the gravitation force balancing but also of the significant encouragement of the halcopyrite extraction. At the same time the action of the field on the pyrite and sphalerite particles is of less significance. The effect can be seen even during the induction in 6 Tl that corresponds to the intensity in 4,8 megaampere.

4. The electric flotation limits were extended
The saturation of the flotation suspension with finely divided electrolytic gas holes during the process of electromechanical flotation is one of the leading tendencies in the effective aeration conditioning of the ore suspension. On the analogy with the static of fluids during the vacuum flotation the following process happens. The finely devided electrolytic gas holes of oxygen and hydrogen penetrate from the outside through the microcracks into the mineral particles. Due to enough contact surface their adsorption into the solid surface with the following coalation with air is pretty strong. More than that the electrolytic gas holes appear directly on the minerals' surface. It happens because of the contact charging of the mineral particles from the electrodes of the electrolysing system.
The electromechanic heating and current flotation includes the advantages both aerating and heating suspension conditioning. To saturate the suspension with finely divided gas holes and to raise the rate of the redox reactions on the minerals' surface is to increase the selectivity of the process.

5. It's the first time the mineralurgical properties of coppersmelting technogenesis have been investigated
The extraction of copper to form a concentrate with approximate 45 per cent refining level (the minus material 74 mkm) in the reverberatory furnaces with the help of the special equipment makes 63-64 per cent. The increase of the milling fineness only by 5 per cent leads correspondingly to this one of the copper extraction by 7-8 per cent.

6. proper know-how was used during the process of industrial development of collective and selective, direct and opposite flotation methods of the continuous sulfide ores and patched copper and zinc ores taking place by four stages
The correlation analysis of the working data of the concentrating mill to determine the quantifiable connections of the flotation results with the mineral composition of the dressing ore and the controlled parameters of the technological process permits to find the opportunities for the increase of the technical index during copper and zinc ore processing taking place by six stages. While processing the compound sulphide raw and source material using the scheme of the collective and selective flotation, the regrinding of the collective and rough copper, zinc, pyrite concentrates and the concentrates of the first copper cleaning allows to rise the metal extraction up to the design index.
And while processing the disseminated ore with high percentage of tennantine in it, the best possible selection can be achieved if using the scheme of the direct and selective flotation taking place in several stages. The scheme of the opposite flotation is the most suitable for the disseminated ore with high percentage of faint minerals which are normally mined out of the old ore deposits. The technological index of their selection is highly correlating with such parameter of the suspension as pH medium.

7. the purification method of the industrial wastewater with oil and fat content was created
The use of the developed flotation schemes for the purification of wastewater with oil and fat content in several cycles with middlings' processing, in case 90 per cent water reclaiming and practical usage of the extracted concentrated products take place, guarantees the local purification structures a full pay-back.

8. it's the first time the model of the flotation machine with the horizontal arrangement of the propaganda and flotation sections has been created
The flotation machine with propaganda and flotation sections arranged horizontally are of new generation comparing with previous ones where separations are vertically arranged with a stabilising grid between them. Horizontally arranged sections are connected by the parabolic channels that guarantee the killing of the turbulent flows. Crew allows to make the speed of running higher and to bring the duration of the flotation's technological process forward the act of flotation in time.
Another advantage of the horizontal flotation machines is that send unloading installation was moved to the flotation section. It allows to transfer the fully saved suspension mass after the propaganda operation further for the flotation. On the same time the sand particles penetrate to the special fairing and move further to the unloading opening that is controlled by the vertical gate. The unloading installation of this type exclude the sand part of the suspension flow to move through the chamber missing the flotation operation.

9. the development of the centrifugal suspension dewatering method under the laboratory conditions was realized using the inert fluid
The centrifugal dewatering of the materials can be used for the learning to handle the automatic unload by the valve system and for the usage of the easily sublimating organic fluid to be a between layer with higher density than water has.
(Epelman M.L., Eldanova I.A. Suspension dewatering method, Inventor's Certificate # 933 112, USSR).

10. The common graphic and tabulated method of the suspension consistency calculations was created for the industrial and laboratory application due to the introduction of the concept of suspension consistency and its computer version
