How to mine uranium
• How to extract uranium
The uranium industry in Kazakhstan in terms of revenue to the state budget is inferior, perhaps, only the oil industry. more than 25 thousand of our fellow citizens are working in this industry, but because of the sensitive sites, guests at the uranium mines - an extremely rare phenomenon. For the first time, "Kazatomprom" made it possible for bloggers to see firsthand how the staff uranium companies live and work. The report shows one day of a mining enterprise "Ortalyk", located in the Suzak region of South Kazakhstan region
Working shift employees LLP "extractive industries" Ortalyk "begins with a mandatory medical examination
Workers uranium mining enterprise measure pressure, temperature, and check on the breathalyzer. Although, according to the doctor, alcohol on site is strictly prohibited, and there was not a single case in which the last test was "defeated"
After a medical checkup - breakfast in the dining room of the mine
Gani Council works on uranium mining companies "Ortalyk" apparatchik-hydrometallurgy, in parallel studying at home in Karaganda State Technical University, majoring in "Metallurgy"
The specifics of production creates additional safety requirements - work clothes employees put in a separate locker room, out there in the field camp and clean mine zone is prohibited
change Master gives outfit - a task that determines the content, place of work, the time of its beginning and end, the conditions of safe performance, the necessary security measures Page
One of the safety measures is wearing respirators in the shops. This is due to the fact that in the production of uranium using reagents such as sulfuric acid, ammonium nitrate
Uranium production is fully automated. The operator can keep track of all the processes that occur at the facility
Uranium mining in the "Ortalyk", as in all other enterprises of Kazakhstan, is the method of in-situ leaching. This method is chosen because it is the most environmentally friendly. The radiation background in the fields is not different from background radiation major cities
The principle of the method of in-situ leaching consists in the following: the ground in uranium-bearing layers is injected a 2 percent solution of sulfuric acid, which reacts with the species, dissolves the uranium enriched in uranium then this solution was pumped to the surface. Above each well worth the pump control panel
In this room at the landfill site with wells located solutions distribution unit
Employees give glasses and hats, which protect from the incredible heat
Through these pipes in the well is pumped sulfuric acid solution. Similarly, look and the pumping wells that pump out uranium out of the ground
solution is then piped to uranium is sent to the shop solution processing (sorption-regeneration cycle).
In this method of production at "Ortalyk" is used about 15 tons of sulfuric acid per hour
The production of uranium, all processes are automated, but it is possible and manual control
In this workshop comes solution of uranium - uranium trade desorbate
The solution interacts with ugleammoniynoy salt to get the natural uranium concentrate - "yellow cake"
filter press readings Checking
yellowcake, or concentrated natural uranium - the final product of the enterprise, which is packed in special containers. Actually uranium in this compound is about 45-50%. In total this year is expected to produce 1,600 tonnes of uranium in the next year - 1800 tons, and in 2014 the company will reach its design capacity of 2,000 tons per year. Needless field for 25 years.

Submersible pumps almost do not need to be repaired, they produce about 30 thousand hours of operation. However, we must constantly carry out the audit and, if necessary, change the impellers
Head portion Murat Nauryzbaev. I received two degrees in chemistry. In parallel with direct mining of uranium in the laboratory conducted the study, which allow the most effective of the deposit
According to accepted standards in the solution directed back into the bowels, after processing should remain no more than 3 milligrams per liter of uranium, but the results do not exceed the loss of the samples 1, 2 milligrams.
After the end of the working shift in personnel radiation dose necessarily checked
When we went to the company, it is expected that the field camp uranschikov will look like in the good old days - trailers, in which the workers huddle. However, a shift camp on "Ortalyk" looks quite different - it is a modern building complex, which is all that a person needs to relax after work. The first came in the field camp, Ghani takes keys from his room
After dinner, many workers spend their time table tennis. At this time, a pair of Gani was Aidos Kenzhebaev who have 3 years working in the uranium industry fitters. Aidos himself hails from Zhanatas village, Zhambyl region
Backgammon compete in popularity with active sports
Nurzhigit - originally from Shieli district of Kyzylorda region, seniority 24 years old, of which the last few years - "Ortalyk".
In the shift camp and have your mini-football field
After table tennis Aidos often spends time at the gym
