Chapter 207 Magnetic Levitation (Please vote, please)
Floating in the air, are you kidding me, why did it suddenly change to a fantasy style, is there a sect on the island or something?
This is impossible, this is impossible, Luo Chong warned himself again and again, this world should not violate the common sense of physics, at least not at present, so how to explain this phenomenon with physics?
Floating, in the air, magnetic levitation?
There is a huge magnetic ore vein in that place, so there is a giant piece of iron ore, because of geological activities similar to earthquakes, it was separated from the ground by the main ore deposit below, and was repelled from the ground by the principle of magnetic poles repelling each other, floating in the air, and then it was pulled by the vines, so it did not bounce off?
This conjecture and explanation is very reasonable, because it does not violate Luo Chong's understanding of physics, but it is also very bold. If this hypothesis is true, then this will be a super-large iron ore that breaks through human cognition, and it is also a very high-grade magnetic ore vein.
This is not a fantasy. There are similar things on Earth. There is a super-large iron mine in the Bear Country, which is recognized by the world. Its mining even affects the magnetic field of the entire Earth. This is really not an exaggeration, but there is no floating island there, and the iron mine is not magnetite.
Magnetite is formed by the accumulation of magma. Among hundreds of minerals containing iron, magnetite has the highest iron content, which can reach about 72%.
Hematite is second, but it can also be around 69%.
Limonite is very mixed. To be precise, limonite cannot be called iron ore. Most of them are symbiotic with other minerals. It also has the most impurities, so it is impossible to make specific statistics. Some local areas may have a high iron content, but if you take two more steps, there may not be much iron.
Although pyrite also contains iron, it is ferrous sulfide, which contains a lot of sulfur. The iron content is usually between 30% and 40%. This data is very embarrassing.
Because if you use pyrite to smelt iron, its cost is very high. First, it wastes fuel. You may use a lot of carbon, but you don’t get much iron in the end.
Moreover, calcining pyrite will produce a large amount of sulfide gas, which is particularly polluting and can easily cause acid rain. Therefore, pyrite is mostly used to extract sulfur or to prepare sulfuric acid by dry distillation.
In this way, the high content of sulfide in it can be used without polluting the environment. At the same time, the sulfuric acid obtained is much more expensive than the insignificant iron in it.
For example, if you use the same volume of pyrite to produce sulfuric acid, you can earn 1,000 yuan, and it is environmentally friendly and pollution-free. At the same time, you will also obtain by-products such as iron oxide crystals.
However, if you use these pyrites to smelt iron, the iron smelted is only worth a few dozen yuan, and the large amount of sulfide gas produced in this process will cost hundreds of yuan to deal with. After calculating this account, what will you do? You don’t have to think about it, right? It must be used to smelt sulfuric acid. Sulfuric acid is the cornerstone of industry. This is why Luo Chong did not use the pyrite from Babaoshan to smelt iron.
But magnetite is different. This is the highest grade of high-quality iron ore. It is a top-grade product with an iron content of more than 70%, which can be directly used to make steel.
If Luo Chong's conjecture is correct, just imagine how huge the mineral vein must be to produce such a strong magnetic field to lift up a small mountain. It's exciting to think about it.
Luo Chong was crooked on the spot, lost in fantasy. In the future, I can brag to others that I have a mine at home. 23333
"Chief, chief, what's wrong with you?"
Dali, one of the five cavalrymen, saw Luo Chong in a daze and asked carefully.
"Ah? Ah, I want to go to that fairy lake to have a look. There might be something we need there, and a lot of it." Luo Chong came back to his senses and wiped the saliva from the corner of his mouth and said.
"What do we need? Is it white salt? But don't we have it in our tribe? Why do we have to go so far to get white salt?" Dali asked puzzled.
"It's not white salt, it's something that can hold the island in the air." Luo Chong raised a smile that only a nouveau riche who made a fortune would have.
"Something that can hold the island in the air?"
Several cavalrymen were stunned in surprise. The guide beside him didn't understand what he heard very well. After Dali explained it to him again, he looked at Luo Chong in disbelief.
The guide had just joined the Han tribe for two days and didn't know what Luo Chong had done before. But now that he heard that Luo Chong actually knew what could make the island float, he couldn't help but regard Luo Chong as a fairy. Otherwise, how could ordinary people know how the fairy island was formed?
"Chief, are those things you are talking about the vines growing under the fairy island? Are those vines lifting the island instead of holding it? But what do we need those vines for?"
The guide told Luo Chong his guess, and because he thought Luo Chong was so interested in the lacquer grass, maybe the fairy island attracted Luo Chong to a strange plant.
"No, it's not the vines, but the small island floating in the air. That small island should be a whole big stone. I want that kind of stone." Luo Chong explained.
"Stone, is that the ore that the chief said?" Dali guessed.
"Yes, it is very likely an ore, an ore that we need very much. If it is true, we must get it." Luo Chong said in a firm tone.
Seeing Luo Chong's reaction, several people around were a little scared. It seemed like he was going to risk his life.
"Chief, what kind of mine is that? Is it more important than our copper mine? It is so far away from us, do we have to get it?" Dali didn't understand Luo Chong's thoughts.
"Yes, if it is true, we must get it. That ore is called iron ore, which is also a metal. It is more difficult to refine than copper ore, but it is lighter and stronger than copper. If a piece of iron hits a piece of bronze, the bronze will be directly broken. Do you want it?" Luo Chong briefly introduced the metal iron.
"Is there such a powerful thing? I always thought that bronze was the best thing. The bronze spear made of it is so sharp. That thing called iron is actually more powerful than bronze!" Dali exclaimed in surprise.
"Of course, iron is not only more powerful, but also can be made into many things. It's just that it is too difficult to make. Unlike bronze, it can be directly burned into copper liquid and cast. It is too difficult to burn iron into iron liquid. You can only keep hitting it with a hammer, but we must make iron, so that our tribe will become stronger."
