The scroll was placed on the conference table. Lin Dong rubbed his sore arms: "It's so heavy. Boss, I told you not to use so many materials. It's so heavy that it can exhaust a person to death."
Li Mingda: "This will ensure that this thing can be stored for a longer time. You don't want to draw a second picture in a short time."
Lin Dong wailed and begged for mercy: "Boss, pull him down, and let others copy him in a few years."
Li Mingda told Lin Dong some bad news: "This map is a secret. Currently, we are the only ones in the Tang Dynasty who can see it, so you will be the one to keep it for the next fifty years."
Fifty years~!
Lin Dong bowed his fingers: "It's so long, can it be shorter?"
Li Mingda shook his head and said seriously: "No, in this era, these are all secrets, especially the geographical maps of mining areas, mountains and rivers, and the specific distribution of rivers. Even today's military maps are not without this detail, what do you think?"
(⊙o⊙)
ε=(´ο｀*)))Alas
"ok, I get it"
Knowing that the matter was serious, Lin Dong didn't say anything else. He opened the map and untied the heavy scroll layer by layer. He found that there was a layer of thick gauze inside. The gauze was untied to reveal a layer of silk cloth. Under the silk cloth, It's a layer of yarn and white paper.
Uncover it again, and you can see that there are several thick layers stacked inside. What these packages are tightly packed are the geographical maps of mountains and rivers depicted in the map scrolls, and the water systems, rivers, mountains and rivers. The direction is very complete.
The total length of all the maps exceeds 9 meters and the width is three meters. Wu Jue's eyes almost bulged out from such a huge drawing. There are nine long drawings, and each one is so detailed.
Wu Jue did not dare to touch
She thought it was just such a big picture, but she didn't expect it to turn out like this. How did His Majesty the Mingzun Saint Emperor come up with the idea, and how did Lin Dong do it? They were all fairies descended to earth.
Lin Dong looked at Wu Jue in a daze. She, a patient with hyperamnesia, didn't want to look at the terrible drawings she had drawn for a second time.
"Xiao Wu Jue, what are you thinking about?"
"No, it's nothing."
Wu Jue was a little secretive, but Lin Dong asked Wu Jue in a low voice with a smirk on his face: "Are you thinking about what the Heavenly Palace is like? Are we the gods descending to earth, the fairy Lin Fan or something?"
Wu Juo hurriedly shook his head and denied: "No, absolutely no. How could Juo'er think that?"
Upon hearing Wu Jue's words, Li Mingda, Murong Xue, and Lin Dong all knew that she was lying. It was enough to make Wu Jue happy, and there was no need to be serious.
After carefully comparing the map silently, he began to say slowly: "According to the mining areas that I know so far, they are roughly divided into seven major mining areas, namely the Anshan Mining Area, the Qianluan Mining Area, the Handan Mining Area, and the Daye Mining Area. Mining Area, Wuning Mining Area, Panzhihua Mining Area, Shilu Mining Area”
“I have already mentioned the characteristics of Anshan’s mining area in Anshan, the first brother, and then there are the conditions of the other six mining areas.” Peerless Tangmen fo
Li Mingda gestured to Lin Dong to write it all down. Lin Dong returned the gesture with an O to show that he understood, and picked up his pen to start his secretarial work.
"Qianluan Mining Area, Qian'an and Luanxian areas in Hebei Province are one of the largest iron ore belts. Among them, Qian'an area has the most abundant reserves, with reserves of about 5 billion tons. It is shallowly buried and easy to mine in the open. The iron ore can be sent to Beijing. In the Jintang area, after smelting, go directly westward and upstream of the Yellow River. The ore in the mining area is poor in magnetite, contains acidic gangue, has little S and P impurities, and has good ore selectivity."
"Hanxing Mining Area, Handan and Xingtai areas, the area's ore has a single composition, high grade ore with an iron content of 40%-55% and considerable reserves. It is easy to select, easy to refine, and has high efficiency. Your Majesty can choose it as some parts in short supply if necessary. The disadvantage of raw materials is transportation problems and it is far away from effective river channels. It is recommended to make ironclad on the spot."
Wu Jue raised his paw at this time
Li Mingda allowed her to interrupt: "Go ahead."
"Your Majesty, this iron mine is currently in use. The late emperor was in charge of this place when he stayed in Taiyuan. Later, he had wars with Wang Shichong and other princes because of the mine."
Um
Li Mingda nodded with satisfaction: "My memory is good, I will reward you with something later, Mo Mo, please continue talking."
Mo Mo took a sip of water and continued: "The Daye mining area mainly includes Tieshan, Jinshandian, Chengchao, Lingxiang and other mines, with relatively rich reserves. The ores are mainly iron-copper symbiotic ores, and the iron minerals are mainly magnetite, followed by Hematite, the iron content of the ore is 40-50%, and the highest is 54-60%. The ore has poor reducibility and needs to be calcined in a blast furnace. I don’t know the specific method. I just read some information.”
"The iron ore producing areas in the eastern area of Wuning Mining Area are mainly Aoshan, Nanshan, Gushan, Taochong, Meishan, Fenghuangshan and other mines from Wuhu, Anhui Province to Nanjing, Jiangsu Province. Jinling Town and other places in Shandong are also quite rich in iron ore. Iron ore resource reserves.
The iron ore in the Wuning mining area is mainly hematite. The iron ore is of high grade, and some of the rich ores contain 50%-60% iron and can be directly smelted in the furnace. The ore has good reducing properties and has certain solvent properties. The average alkalinity of the rich ores in Aoshan and Meishan can reach 0.7-0.9. Some ores contain vanadium, titanium, copper and other non-ferrous metals. "
At this point, Li Mingda asked Mo Mo curiously: "Is titanium the titanium we know?"
Mo Mo nodded: "Yes, this is titanium, but it is not the largest. It is the sixth place at most, the Panzhihua mining area. The proven reserves of vanadium-titanium magnetite are nearly 10 billion tons, of which the reserves of vanadium and titanium are respectively in the world. Ranking third and first in the world, it is known as the "Vanadium and Titanium Capital of the World". The ore is also accompanied by chromium, scandium, cobalt, nickel, gallium and other useful minerals. Therefore, this area is extremely important. I suggest that your Majesty Seize the moment”
Li Mingda took a breath of air. He had been busy for a long time and figured out a fake Panzhihua. It was actually a mine in Wuhu. The real Panzhihua, a big killer, was still buried in the same place waiting for him to go first. Open the hijab and take it home.
Um
No, the whole land of China belongs to my Tang Dynasty. I am already at home, waiting to take off my hijab first.
Hey hey hey
Mo Mo looked at Li Mingda without saying anything, and continued: "The last Shilu mining area is a rich iron ore. In Hainan, it was the largest open-pit iron mine in Asia at a certain period, and "the richest iron ore in Asia", with reserves of up to More than 400 million tons, with an average content of 51.2% and a maximum grade of 68%. The cobalt ore reserves associated with Shilu Iron Mine are 3.705 million tons and the amount of cobalt metal is 9,987 tons."
(⊙o⊙)…
Murong Xue and Wu Jue were both stunned. The seconds they watched him were calculated in billions. In the past, when Li Mingda did not rise, the output of iron ore and iron and steel in Datang was not increased in a year. Now.
It was as if a poor man who was about to starve to death found out that there were actually countless grains buried in his own land. He only knew how he felt.
Li Mingda was excited
