By Klavdiya Romakayeva - Trend:
Uzbekistan Railways JSC together with the Austrian Horst Wiesinger Consulting GmbH consulting company completed laboratory and pilot tests for the extraction of concentrated ore concentrate in Tebinbulak mining and metallurgical complex, Trend reports citing Uzbekistan Railways.
Uzbekistan Railways JSC is implementing an investment project for the integrated development of titanomagnetite ores in accordance with the Decree of the President of Uzbekistan "On the organization of work on the implementation of the investment project Construction of a mining and metallurgical complex based on the Tebinbulak deposit”.
The resource reserve of the Tebinbulak deposit, estimated according to the JORC code, amounts to about one billion tons. According to preliminary calculations, it is planned to extract 27 million tons of ore per year at the deposit and receive 1 million tons of rolled steel and vanadium slag from it.
To date, the implementation of this project has already passed several stages. Uzbekistan Railways JSC together with an independent consultant represented by the Austrian Horst Wiesinger Consulting GmbH company completed laboratory and pilot tests for the extraction of concentrated ore concentrate, granulation, and reduction of iron using natural gas, steel production, and separation of vanadium slag from steel.
Earlier, it was reported that the project provides for the use of an embedded technology, which is remarkable in that, unlike blast furnaces, it does not pollute the environment.
Despite the poor iron content in the ore, with the help of the selected technology and the extraction of vanadium slag as a product with high added value, the project is economically viable with a payback period of 8 years.
TÜV NORD GROUP divisions - a large consulting and engineering company DMT Group (Germany), Leoben Mining University (Austria), Bochum University (Germany), research centers such as SGA (Germany), K1Met (Austria), ARP (Austria), ALS (Ireland), as well as business consultant ILF Consulting Engineers (Germany) participated in the development of the project.
In addition, in order to obtain the opinion of an independent expert on the technology adopted in the project, the TOMS Institute (Irkutsk, Russia) carried out three-stage technological studies for the enrichment of ore samples from January to September 2020.
The results once again confirmed the possibility of enriching iron ores by obtaining a concentrate with an iron content of more than 67 percent. The research was carried out on a representative ore sample in the amount of 2.7 tons, selected by the international company SRK Consulting (Canada).
