LOOKING FOR URANIUM
Professionals and beginners uranium prospectors from time to time are trying to find the right place for uranium deposits. For this, they are used to read old information and develop all their efforts in each prospection day. Some places, such as The United States or Canada are looking for new mineral sources of atomic energy.
Many times, the seekers are motivated for the special reward that an authority is used to give. However, many of these seekers lose their time in places where would be difficult to find uranium in the minimum grade to be mined, but there is the possibility of detracting many affirmations from some miners that couldn’t find any evidence of uranium.
The Energy Board of each country is used to see samples from all places where it is possible to find uranium or other radioactive material, but, also the Board says to the prospectors that the reasons must be chosen with base and fundament and no randomly. Thus, has been reported that some people misinformed or blinded by the emotion present samples without any value.
One of the most important discoveries was done by the Canadian, Robert Campbell who made a preliminary work in the library of Toronto. He read some reports from copper explorers of the XVIII century, and discovered some references of uranium near to Sault Ste. Marie. At that time, uranium was not important and nobody made any effort for its use as energy source.
Equipped with a Geiger-Muller Counter, Campbell spent some time in the reported region in the old documents. Thus, he explored the Coast of Superior Lake and climbed many hills with an altitude of 300 meters during his explorations. Many weeks, he only heard normal cracks that are common to find in any place, but one day, while he was exploring a placed called Alone Bay, he several times heard a strong crack in his earphones. At that moment, Campbell was standing up a few meters of a vein of black pitchblende. If the ore has 10% uranium, it considered very valuable. Campbell’s vein had 60% uranium.
Now, many countries will find new uranium deposits with much difficulty in order to satisfy all their needs. The main deposits are found in Canada, Australia, Kazakhstan, Niger, Russia, Namibia and The United States. In The States, the main uranium deposits are located in the border between Colorado and Utah. Some places had reported low grades of uranium and its extraction trends to be complicated.
Some time ago, the Atomic Energy Board in The States tried to find all the possible amount of radioactive ores with a reasonable content of radioactivity. In 1949, the government announced rewards of 10,000 dollars for 20 tons of uranium ore or concentrates with more than 20% uranium oxide from new deposits. To this amount, the Board promise paid the uranium content in the ore. The offer was not applicable for carnotite from Colorado. At that time, the price was 0.70 dollars per kilogram of uranium oxide recoverable from the ore. Carnotite ores had variable price in the range 0.66 to 3.30 dollars per kilogram of uranium oxide. At that time the deposits with less than 0.10% uranium oxide were not acceptable.
