"Can it be better?" Murong Hai gasped, Lutan Village was originally an ordinary village selling animal skins, and after Fang Ruitao's improvement of the blacksmith shop, the biggest income in the village actually changed from selling animal skins to smelting iron, which made the whole village benefit.

Now the villagers of the entire Lutan Village are enthusiastic about Fang Ruitao, and everyone with a girl of the right age is wondering if they can recruit him as a son-in-law, even their own money-obsessed father is no exception, and he is bent on marrying his sister to this kid. Now he actually said that the iron-smelting process can continue to be improved, if then the price of the weapons produced by the blacksmith shop will naturally roll upward, how much profit there is, Murong Hai can't think of it, but one thing he can be sure of is that if there is really such a thing, Fang Ruitao will definitely be even hotter in Lutan Village. Murong Hai secretly warned himself that he must tell his sister when he goes back and let her take the initiative.

"The level of mining ore is down there, and you can go there and see it. Murong Hai led Fang Ruitao directly to the work surface, where more than a dozen villagers were struggling to mine ore with a pickaxe. Looking at the steel pickaxe in everyone's hands, Fang Ruitao smiled slightly, in order to improve mining efficiency, the village really made the capital, and actually made these miners the first batch of people to use steel tools, which shows that the old village chief attaches great importance to iron ore.

Since many people in the village have cultivated and have a fighting spirit, although the level is generally not high, its mining efficiency is definitely not low. Seeing the villagers working in full swing, Fang Ruitao smiled in return, he walked to the mining section, stroked the russet rock section, Fang Ruitao asked secretly in his mind: "Nineteen, how about these iron ores?" ”

Fengyun No. 19's voice sounded in Fang Ruitao's head: "No wonder I think the steel forged by Blacksmith Zhang is a little strange, it turns out that the phosphorus content is too high. These ores have been determined by me to be phosphate iron ore. Because these ores contain phosphorus, there is nothing when forging at high temperatures, and once the temperature of the iron billet is too low, it will appear cold and brittle. In other words, when forged at low temperatures, this steel is brittle and prone to breakage. ”

Fang Ruitao frowned slightly and said, "Is there any solution?"

Fengyun No. 19 said: "Fortunately, the phosphorus content of these phosphate iron ores is not high, but the iron content is as high as more than sixty percent. ”

"I'm mining sulfide-molybdenum-tin-copper ore, what does it have to do with iron smelting?" Fang Ruitao said strangely.

Fengyun 19 is worthy of the most advanced soul chip, and it quickly gave the answer: "Originally, this kind of phosphorite dephosphorization is best done by flotation, but we lack sodium carbonate and sodium silicate now, and this method is difficult to carry out at all, so we have to use the leaching method." The leaching method originally needed to use calcium chloride and ore to calcinate at a temperature between 800 and 1,000 degrees, but the phosphorus content of this ore is not high, we can omit this step and wash the ore directly with dilute sulfuric acid, which can directly remove the phosphorus inside, but the ore needs to be turned into powder in advance, and we need a ball mill. ”

Fang Ruitao nodded and said: "We should still have these, it seems that my sulfuric acid needs to consume a lot, but it's nothing, anyway, there are veins there, and the ore needs to be more or less." ”

Fang Ruitao and Fengyun 19 communicated in their consciousness, but in Murong Hai's opinion, he had been looking at the ore in a daze without saying a word. After waiting for ten minutes, Murong Hai couldn't help it, and he asked, "How is it, do you see anything?"

Murong Hai's words made Fang Ruitao sober up, and he smiled at Murong Hai and said, "There should be room for further improvement, wait for me to go back and give it a try." ”

"Can it really be improved?" Murong Hai looked at Fang Ruitao with wide eyes, looking incredulous, originally he thought that Fang Ruitao was just talking casually, but it turned out that it was really possible.

Fang Ruitao smiled and waved his hand: "Not necessarily, I think it should be possible." ”

"What do you think of my sister?" Murong Hai asked suddenly.

"Huh?" Fang Ruitao's mind didn't react for a while.

"Oh, nothing. Murong Hai also blurted out with a hot head just now, this god of wealth in the whole village is really shocking, so Murong Hai is so out of shape.

"Pretty good girl. Thinking of that beautiful and lovely face and body that had begun to develop, Fang Ruitao's heart couldn't help but waver, a fifteen-year-old boy has reached the age of the first love, and he is no exception, it is very normal to pay attention to beautiful girls.

"Really? Great. Murong Hai was overjoyed when he heard Fang Ruitao's words as if he were talking to himself.

"Mine manager, there's something strange about this, the color of the ore has changed. While the two were talking, a miner shouted loudly, and the mine manager in his mouth was naturally Murong Hai.

Hearing the call of his subordinates, Murong Hai immediately walked over, and the curious Fang Ruitao also followed. When they got closer, the two found that in the russet layer of ore, a pale blue crystal was exposed, and under the miner's pickaxe, the crystal was partially smashed, and the fragments were scattered nearby, apparently these crystals were not hard.

It was the first time Murong Hai had seen this kind of thing, he scratched his head, he had no concept of these things at all, and when he was embarrassed, Fang Ruitao stepped forward quickly, overtook him and walked directly to the vicinity of the crystal. Squatting down and picking up a few crystals, Fang Ruitao observed it carefully, in fact, he was asking for help from Fengyun 19.

"This is phosphate rock, which is an associated ore of phosphorite. Fengyun 19 quickly gave an accurate answer.

"Good stuff. Fang Ruitao blurted out when he heard the answer of Fengyun 19.

"Is it a good thing? What is this?What is it for?" Seeing that Fang Ruitao knew this kind of thing, Murong Hai was also interested, and he immediately came up and asked.

"This is phosphate rock, as long as it is ground and crushed, it is a very good fertilizer, which can greatly increase the yield of the crops grown in the village. What Fang Ruitao didn't say later was that this phosphorus was a very good chemical raw material that could be put into his chemical plant for application, and in addition, he could refine white phosphorus and use it to make white phosphorus incendiary bombs. This kind of incendiary bomb, which is easy to burn smoke and poison, will definitely become his killer weapon in the future. "This ore only needs to be mined in small quantities, and it doesn't need to be given to blacksmith Zhang, so it can be moved directly to me, and then ground into powder, and then sent to the farmers' fields to fertilize the fields. ”

The harvest this time was not small, so Fang Ruitao didn't expect it. Although he didn't find the saltpeter ore and sulfur he wanted most, he still had some self-preservation power due to the presence of phosphate ore, at least after making white phosphorus incendiary bombs.
