Diamond Mining & Cutting Innovations
Diamond abrasive tool on the basis of a powder from natural diamonds and a polymer binder
 The Nonmetal Materials Institute of the Siberian Division of the Russian Academy of Science has developed abrasive materials and tools on the base of the new type of binders (PTFE) and also traditional polymer type (bakelite, synthetic rubbers, resins) both with powdered diamonds with different granulation factors from the Yakutia's deposits.
Diamond tools on the base of the PTFE have a high heat resistance a high efficiency a long life span and practically never need a tool dressing. Application of tools on the PTFE base allows shortening by half the time of production of items from minerals and stones (gems) by eliminating many polishing operations.
On the base of synthetic rubbers are developed hard and elastic tools with enhanced heat resistance heat conductivity. The soft-based tools are mainly used to work on the geometrically complex surfaces. The main application of hard instruments on an ebonite base is a roughing phase. The soft on the rubber base are used in honing.
All developed tools are intended for work on the raw minerals and gemstones as well as metals and their alloys including precious ones.
They can be used with or without cooling and lubricating fluids.
The offered production: Tools can be made in standard shapes and sizes as well as specified in the order.
The cost of tools: it is determined by the price on the natural industrial diamonds.
Electro-chemical technology of discoloration and decontamination of drinking water in northern regions
 The water treatment technology of water from natural resources is using electro-chemical method of receiving discolored and decontaminated water. It is done in the facility called “Sever” (sever-north in English). It was developed by IPKON of the Russian Academy of Science, Alrosa, Inc. and PTI of the Yakutsk State University . The blueprint of the facility incorporates mechanical filtration, decontamination, electro coagulation, with soluble anodes, than separation of the sediment from cleaned water, and the final control filtration, and finally the additional decontamination. Chromaticity of the treated water is 2-5 degrees (hygienic norm- 20 degrees, and initial value 120-300 degrees), and there are no chemical reagents. The “Sever” facility is intended for utilization in the single buildings, small settlements, industrial objects, agricultural enterprises, health care facilities, food facilities, etc. It also can be used for cleaning an industrial sewage. The “Sever” facility is manufactured in several modifications depending on the necessary output (from 1.2 to 240 cubic meters per 24 hours)( 1 cubic meter = 1000 liters = 264.25 gallons ), and depending on the connection to a specific object, and can be assembled as a mobile block-box, and as a stationary object. The treatment of water from natural sources in the facility by the basic indicators (without addition of chemical reagents): chromaticity to 98-99 per cent, iron to 99.5 per cent, turbidity to 99 per cent, nitrates to 75 per cent, ammonia and its derivates to 60 per cent.
This technology was tested in the industrial and the residential objects (enrichment plants of Alrosa, Inc., and settlements in the area of Mirny, republic Sakha (Yakutia). The facility helps to lower the cost of a treatment of a drinking water, lowers spending on reagents, and delivers quality water according to Russian norms. It also has a great social effect by diminishing the rate of morbidity. The cost of the water treatment with this technology is 2-3 times lower than with chemical agents.
Electro-chemical technology of discoloration and decontamination of drinking water in northern regions
The offered production: Different sets of the facility “Sever”.
The cost Prices are negotiable, depending on the set of the “Sever” facility, and the degree of the water treatment
The business plan is available.
Electro-chemical technology of water degasation in industrial conditions
 The short description: This technology cleans water from hydrogen sulfide using an electro-chemical method to bind it into insoluble and nonvolatile complexes. This method has been developed by IPKON of
The Russian Academy of Science, Alrosa, Inc., and ПТИ of the Yakutsk State University .
The device is designed for the following conditions:
It is used in mines to clean drainage water from a hydrogen sulfide and prevent it from getting into the air.
It is used in mines for cleaning of an air contaminated with a hydrogen sulfide. The pollutant can either get there from drainage water or from the outside air (ventilation system).
It is used for cleaning of drainage water evacuated by pipes.
The offered production: the experimental-industrial sample.
The cost is negotiable.
The business plan is available.
Technology of explosive pressing of diamond-metallic powder materials
 The short description: There are new perspectives for development of diamond-metallic composites using energy of an explosion. Explosive compressing is an extreme process that happens in high-pressure, temperature, and speed. As a result of a high intensity interaction between pulverized substances there is compacting, high speed heating and deformation accompanied by binding of molecules.
The IFTPS has a developed technology of manufacturing diamond-metal composite from a mixture of pulverized natural diamonds and iron-carbon alloys, which is using explosive compressing and short-time high-temperature heating.
In the base of this technology are following factors which were discovered as a result of a research. They are:
- Intensive densification of the matrix components due to the explosive loading and the following thermal treatment (it makes possible the most difficult to achieve demand which is a good wear ability combined with durability and plasticity)
- A better preservation of a diamond component than in traditional sintering methods
- High diamond content
In the comparative tests durability of the experimental composites is equal to the durability of industrially manufactured diamond pens, which have twice-higher content of a pulverized diamonds.
The offered production: the experimental sample
The cost: negotiable
