Development of equipment and technology for burning fine-dispersed molybdenite concentrates
Small Russian innovative company from Ekaterinburg, specializing in mechanical and metallurgical equipment offers an innovative project roasting molybdenite concentrates. As a result of the new technology simultaneously can be obtained by firing two very sought-after metal: molybdenum and rhenium; molybdenum as the main product; rhenium as accompanying as contained in molybdenite. The company is looking of a partners for technical cooperation to bring development to the industrial design.
The project represents a small Russian innovative company from Yekaterinburg. The company has a number of innovative projects, many of which have been successfully implemented. The company has 20 patents for inventions. The company employs experienced professionals, candidates and doctors of sciences. The project proposes to obtain the necessary industry metals molybdenum and rhenium using the new technology to extract them from molybdenite concentrates.
Originally this project was molybdenum. However, during the research it was found that the extraction of rhenium with concomitant firing of molybdenite in the vortex furnaces obtained significantly more cost-effective compared to all currently existing technologies.
Improving the technology of extraction of rhenium from molybdenite concentrates is important scientific and technical challenge. The industrial production of rhenium is only possible from molybdenum concentrates, in which the rhenium content of 0.05-0.20%. Currently, the technology of rhenium is closely related to the technology of obtaining molybdenum - rhenium is extracted from the waste molybdenum production. Improving technology roasting molybdenite concentrates is currently one of the most pressing problems of rhenium production.
Rhenium is one of the most important elements used in high-tech industries, such as electrical engineering and electrical, aerospace and aviation industry, as well as catalysts in the cracking and reforming oil. Rhenium - a typical trace element. In recent years, its consumption in the industry have been significant changes. For example, expanding its use of special alloys. Its high melting point of 3180°C yields only to tungsten. A good resistance to creep deformation is increasingly attracting attention to this metal as an important component of special alloys for blades operating in the critical sections of aircraft engines. Currently, about 80% of the total demand for rhenium is necessary for the production of special alloys, while 5-10 years ago, only a small amount is used in this field. Most of the remaining 20% - the production of catalysts.
Molybdenum was discovered in 1778, but industrial use has been relatively recent. Prior to the twentieth century. use only some molybdenum compounds, especially as chemicals and dyes. At the end of the nineteenth century. was opened influence of molybdenum on the properties of steel, which has affected the expansion of areas of application. Currently molybdenum is one of the most important alloying metals. Over 90% of the world´s molybdenum in the form of FeMo consumes metallurgy of special steels. Moreover, thanks to refractoriness and low coefficient of thermal expansion of the metal is widely used in electrical, electronics, engineering high temperatures.
The proposed project will significantly reduce the energy-intensive and simplifies the process of "key" redistribution kontsentrate- roasting molybdenite.
As a result of laboratory tests was created Vortex kiln, which is designed for the oxidative roasting of sulfide materials. As a result, long-term research and development have managed to create a new type of kiln, which compares favorably with the furnaces, existing at the moment.
The main advantages are:
1 The reaction from MoS2 to MoO3 held at 98.7%.
2. Rhenium passes into a gas phase in the form of the highest
oxide on 94%.
3 The content of total sulfur (sulfide and sulfate) in the calcine less than 0.3%.
4 dust removal is less than 1.5%
5 Calcination is carried out in one step.
6 Small size.
7 Much less metal
8 High performance.
9 Low power consumption.
The main consumers: Metallurgical enterprises; Electronics and electrics; Cosmic and aviation industry.
Stage of development - TRL-4.
The authors of the project offer the following forms of cooperation to interested parties: partnership to collaborate on a project with bringing technology to the stage of TRL-6, and the sale of licenses.
Advantages and Innovations:
Innovativeness of the project:
· A new method of burning flesh providing small dust removal, high performance and quality of cinder. This problem was solved by using potential aerodynamic vortices, which can improve the contact of the material with an oxidizing agent, and keep the processed material in suspension in the firing process in a vortex apparatus necessary time;
· Minimum dust removal and adjustable time "torsion" of concentrate in a vortex allows for a high percentage of rhenium (94%) of concentrate. It has a lot of commercial interest due to the very high price of rhenium and ever growing demand for it on the world market;
· Proposed new generation of equipment has a significant potential market due to its characteristics over analogues: small size and weight, ease of management and the achievement of high precision technological parameters of the processed materials. In addition, one of the main parameters of the appeal of this equipment is the low power consumption of process (much lower than the existing analogue).
