Uranium is a common natural metal found in soil, rock and water all over the Earth. The Human body also contains between 90 and 150 micro grams of uranium.
Its natural radioactivity is the principal source of heat that prevents the Earth’s mantle from cooling. Owing to this property, uranium has become the main material used by the nuclear industry for the production of electricity.
Traces of uranium occur almost everywhere, in seawater and oceans. Uranium mines are operated in locations where it is found in large quantities.
of uranium produces as much as heat of 2.8 tons of coal
Uranium ore concentrate, commonly referring to as U3O8 or yellow cake, is obtained - after the natural uranium ore has been extracted and processed chemically at the processing plant.
At the beginning, there are 200 grams of uranium per ton and after the process of lixiviation, drying, calcination, we obtain an uranium concentrate containing more than 700 kg of uranium per ton.
Nature has worked for millions of years to form the uranium deposits in the Dornogobi region. Over time, the rainwater has seeped into the sedimentary layers of the Earth and dissolved the natural uranium contained in the rock.
These sedimentary layers are made up of alternating strata of impermeable clay and more permeable sandstone. Water carrying the dissolved uranium circulates through the sandstone layers. When the water encounters a natural environment with a specific chemical composition, the uranium precipitates. A uranium mineralized body is starting to form and may continue to enrich over time.
In this way, large quantities of uranium naturally accumulate at particular trap locations, and it can become economically feasible to mine these concentrations of the mineral. The geologists at COGEGOBI look for such areas where uranium has been deposited and assess them to determine whether the uranium can become an economic resource.
Generating electricity is not uranium’s only use. Uranium and other nuclear materials are also used in space exploration, food safety or medicine. In Mongolia, activity involving radiation occurs in six sectors, according to the Nuclear Energy Commission:
Mongolian State policies support increased exploration of natural radioactive mineral resources. Their objective is to improve the quality of exploration, mining and processing activities and to develop high-tech technologies to produce valued-added products.
All “radioactive mineral resources’ deposits are classified as strategically important without regard to their size” according to the Nuclear Energy Law of Mongolia, and the Mongolian State Policy on Radioactive Mineral Resources and Nuclear Energy.
The Nuclear Energy Commission of Mongolia has signed memorandums of understanding with France, Japan, India, the Czech Republic, USA, Russia, China, Canada and South Korea for cooperation in the radioactive mineral resources sector and the nuclear energy industry to develop Mongolian expertise in the field.
