Main source of uranium

As a radioactive chemical element, uranium plays an extremely important role in national defense, industry and scientific research. Because of its enormous energy release during nuclear cracking, it becomes the main raw material for nuclear weapons. As people's understanding of uranium has changed from the singularity of the past to diversification, more attention has been paid to the development and utilization of uranium.
At present, there are few countries with nuclear weapons in the world, while the nuclear industry countries are constantly developing, and nuclear energy has also changed from a simple military type to a civilian type. Nuclear power plants are typical representatives of this transformation. At present, most of the nuclear power plants in the world use uranium as raw material energy. So people from the previous Amoy gold rush turned into uranium Amoy heat.
According to scientists, the total amount of uranium on the world's land can produce about 2.5 million tons of uranium. That is to say, if the world uses uranium as a raw material to manufacture nuclear weapons, nuclear power plants, and nuclear fuels for aerospace and navigation, then it will not take long. uranium mining on the continent will be an empty, and all the facilities established by whom will become a pile of scrap iron. Of course, this idea is a bit pessimistic.
Experts have also suggested that the total amount of uranium in seawater exceeds 1,500 times the total amount of land. This undoubtedly injects a booster into the country with nuclear weapons and nuclear industry, and people have begun the difficult task of finding uranium in the sea.
After people’s brains burst into flames, they slowly discovered that it was a difficult job! The concentration of uranium in seawater is only three parts per billion, that is, only 3 grams of water per ton of seawater Uranium, uranium is present in the tricarbonate complex in seawater. After dealing with a large amount of seawater, it was discovered that the uranium extracted from seawater can only release energy equivalent to or slightly higher than the energy consumed in extracting it from seawater, which is not worth the loss. So scientists began to explore new ways to reduce energy consumption and get more uranium.
American scientists have used organic trees to look forward to uranium and several other metals in seawater, which has been successful in laboratory research. However, due to the low adsorption rate of organic resins and high production costs, it is difficult to find them in practical industries. application. Later, after a long period of exploration, Rose finally made an ideal new uranium adsorbent - hydrated titanium dioxide, and thus developed a set of titanium dioxide-based seawater uranium mining technology.
Among these numerous research forces, Chinese scientists have made significant contributions to this. They found, aluminum oxide, magnesium hydroxide, iron oxide, zinc strongest absorption of uranium, and has been confirmed in the experiment, if it can be applied in real industry, then the cost will be greatly reduced uranium extraction, which undoubtedly It has made tremendous contributions to the seawater uranium industry.
In addition, some foreign research institutions have also found a more economical and simple method of uranium extraction. They have developed a negative ion exchanger, which has a very significant effect on uranium adsorption. It is excellent in the laboratory, but it is using tidal seawater. In the experiment, it was disappointing. If you want to break through this mark, you need to develop another process - a completely different uranium extraction process.
In short, the idea of ​​seawater uranium is great, and it is difficult to complete this idea. Thousands of scientists and research groups in the world are still working tirelessly. We are convinced that one day, seawater uranium is no longer a myth, but now we can only list it as an unsolved mystery.

Through machinery transmission, the mixing machine makes the material turning and moving to achieve the goal 

of mixing. It is mainly used for mixing particles and particles, particles and powder, powder and powder, It is widely 

used in pharmaceutical , chemical, food , dye , chemical fertilizer and pesticide industries and especially suitable for 

mixing various solid materials with large volume . It has the features of quick mixing and dischargeing too.
