Interlayer oxidized zone and argillite-sisandstone-argillite sequence occur in red clastic rock formation with ideal artesian and circulating system of ground water.
But an unexpected fact was noted: certain minerals( pitchblende, chalcolite, autunite) had a greater activity than might be expected on the basis of their uranium or thorium content.
We found that pitchblende contains at least two radioactive materials, one of which, accompanying bismuth, has been given the name polonium, while the other, paired with barium, has been called radium.
The assault comes just over a week after simultaneous suicide attacks to the military barracks and the French-administered uranium mine in Niger. Mary Harper reports.
A spokesperson for the French company Areva said a team was going to assess the damage of the uranium sites of Arlit, but production has stopped for now.
The company has been mining uranium for 4 decades in Niger and is negotiating a new ten-year contract with the government which will give it a greater share of the profits.
Militants in Niger have killed more than 20 people in two almost simultaneous suicide car bomb attacks targeting a military barracks and a uranium mine in the north of the country.
Large deposits of coal and natural gas, as well as a three percent chunk of the planet's oil reserves and 40 percent of its uranium mean that Kazakhstan's people could be rich.
That's because for the first time, inspectors from the IAEA — the International Atomic Energy Agency — will be looking, measuring and monitoring the entire nuclear fuel supply chain from the Uranium mine to the centrifuge.
