Mining in Iran is still under development, yet the country is one of the most important mineral producers in the world, ranked among 15 major mineral-rich countries, holding some 68 types of minerals, 37 billion tonnes of proven reserves and more than 57 billion tonnes of potential reserves worth $770 billion in 2014. Mineral production contributes only 0.6 per cent to the country's GDP.

Eudialytes are mildly radioactive, but wearing or handling pieces under 5 cts (1 gram) should pose no health risks. On the other hand, holding a eudialyte sphere of 5,000 cts (1 kg) — a very large piece, indeed — would expose you to 2.40 mREM per hour. To put that in perspective, the average annual estimated radiation exposure in the U.S ...

The Central Bank of Iran has declared that licensed banks and moneychangers in the country can use cryptocurrency that has been mined by officially sanctioned miners to pay for imports, according to a report from the Financial Tribune.. Hit hard by international sanctions, Iran likely sees the use of cryptocurrency as a way to operate outside of traditional financial controls.

In the eudialytes of the Ilimaussaq deposit, the Mn/Fe ratio is 0.16; in the eudialytes of the Lovozero ores, the Mn/Fe ratio is 0.95. In our opinion, the degrees of differentiation of the Greenland and Kola Peninsula deposits are very close; the variation is caused rather by the different compositions of parent magmas (the alkali basalt ...

According to a report from the state-run Iranian Students’ News Agency (ISNA), Iran has established new regulations to funnel Bitcoin mined by Iranians into state coffers so it can use them to pay for imports.. The edict, put forth by the Ministry of Energy and Central Bank of Iran (CBI), requires the country’s legally registered cryptocurrency miners to sell the tokens they mine to CBI.
