Yu Weichao, Nude Xiong, Li Changning, Li Feng, Jin Doona, as well as 55 students from the newly formed Mineral Mining Department, plus more than 30 carefully selected Xijiang natives, watched the performance of bacteriological metallurgy. 【Reading.com】

The usual way of bacteriological metallurgy is to dip the solvent on an ore pile, it will slowly eat the ore, and then discharge it out, in view of the nature of the bacterial grouping, so as to separate the metal in the ore and complete the metallurgical step. This method can be used both on the ore piles that have been mined and on the mines that have not been mined, where the cost of leaching is relatively high, but the cost of extraction is saved. The time of immersion is very long. Moreover, each different mineral deposit should be cultivated with different strains - mainly the robust, digestive, and fast reproduction strains are selected, and the selected strains are cultured in large quantities and then soaked and moistened.

The "Iron Fungus Week" is different, it is a reusable strain because it works with a wide variety of metals, and when Chen Yi poured 10 tons of solvent into a pool covered with ore, 500 meters long and 200 meters wide, he even submerged only a tenth of it.

"A little little?" Yu Lei felt that he was mistaken.

"It's going to fill up at the bottom of the pool in no time. It's an accumulation process. Yu Weichao, who used to be a scholar, said in an extremely envious tone at this time: "The iron fungus week will definitely change the world's metallurgical industry and mineral industry, and it will make many of the previously invented refining methods useless." Once the biological refinery finds the right strain, it will be like an industrial machine and will have a huge change in the industry of the whole world...... It's a bit slow though. ”

Yu Weichao said very seriously: "Don't look at the slow efficiency of the iron fungus week now, but as long as it is cultivated from generation to generation, it is equivalent to the discovery of penicillin and completely changing an industry." We now have 10 tons of solvents, I don't know how many units, slowly there will be 100 tons, 1000 tons. The problem is only that after screening, some mutated bad strains must be discharged, and there is also the substrate after fermentation, which is the excrement of bacteria...... What will be our production now? ”

Jin Doona got the information and read it in a low voice: "In the first month, it can process 6,000 tons of ore, which is equivalent to about 10,000 boxes of iron mill god boxes, with an average of 200 tons per day, and by the second month, the strains in our solvent have completed logarithmic reproduction, and the output will jump 10 times, reaching 200 tons per day, that is, 60,000 tons per month, and the final goal should be an average of 20,000 tons per day, and 30 such pools should be opened at the same time, and then there will be output every day."

"The metal produced still needs to be refined, right?" Yu Weichao recalled the common sense of bacterial refining that he knew, and said: "If it is iron ore, what we produce should be pig iron." It also needs to be reprocessed into crude steel, and then used crude steel to process the steel we need. But pig iron can be sold to people in the West Continent. ”

"Let's divide it into several grades." Chen Yi gave a suggestion.

A few people were discussing the direction of development there, and suddenly someone in the team of students began to shout: "Melt, melt", and then look at the ore in the pool, and the surface is indeed a little melting.

"This is just the first step for bacteria to eat the ore, and it will take a long time for them to digest." Chen Yi had seen Professor Zhou Houyuan's performance, and now expressed his dissatisfaction: "He said that it will take a long time of screening and cultivation to get a better strain, that guy...... It took thousands or even tens of thousands of years to breed strains, and finally found a superbug that could swallow all known metals......"

The pentagram on his chest flashed, and he was probably humbled and humbled by it, so he simply shut up in a huff.

Yu Weichao said with a smile: "He has indeed improved the efficiency of bacteria, although it is not much, so let him go." ”

Chen Yi shrugged: "The current ferrobacteria perform well for non-ferrous metals, but not for ferrous metals, so ...... Let's deal with the ore here. ”

Unlike the precarious people of the Western Great Land, Chen Yi really doesn't need metals that can adapt to all metals, at least not so many kinds.

"We may need a dedicated laboratory and experimenters to screen for bacteria." "This way we can gradually accumulate more bacterial liquids, if they can be reused," Yu advised. ”

"Do you know anyone?"

"How about Zhou Houyuan?" Yu Weichao was a little evil-hearted, he really didn't want Zhou Houyuan and his "Iron Fungus Week" to accept everyone's cheers and praise on the earth.

Chen Yi really nodded. He didn't care what Zhou Houyuan thought, as long as it was in the interests of Xida Lu, it would be good to compensate Zhou Houyuan later. In addition, this can also avoid Zhou Hou Yuan Liyun using strains to make profits-making things, of course, can only be done by Chen Yi alone.

After watching the performance of bacteria eating ore, the group went to Magical Mountain.

After more than two months of "cleaning up the jungle war", not only was there a 5-kilometer standard highway connecting the ring road, but also a heavy-duty road was built to reach the Xijiang walled city.

In fact, after gaining experience, it is not so difficult to reclaim the jungle, the core of which is to empty the swamp water, prevent mosquito attacks, and strictly control the number of various monsters. In addition, the control and use of Mexicans is also very important, they are very good laborers, and in a way, these poor Mexicans who have tried countless means of livelihood are more suitable for the environment of the western continent than the middle of the country who came from Jiangbei workers. It's just that their identities have not been recognized by the diamond-shaped council chamber, so they do more work than the Chinese people, and risk more danger than the Chinese people, but they still have not been promoted and their salaries increased.

Their income is only one-tenth of that of the average student, and the points subsidy in the Western Continent is only slightly better than that of the indigenous officers, and this alone makes them not respected by the indigenous officers.

Magical Mountain can no longer be called a mountain, as a strange mine where gold, tin and platinum coexist, its value is undoubted, so Xijiang Shuizhai also grasps the ore mining very tightly, and the medicinal use of fried selding is fast and many, and now there is no longer a lush village on the mountain.

Judging by their plans, at most three months, the mountain will be gone.

"How long can we mine?"

"For a long time, we didn't know how many reserves there were below.

But it's definitely not big. Yu Weichao's expression was excited, judging from the situation of Xijiang Water Village, just such a mine is enough for it to eat and drink. He pointed to the excavator that was working below, and said: "I have checked the information, on the earth, platinum is associated, especially the platinum of the Chinese country, all of which are obtained by the way when collecting other metals, and it takes about 10 tons of ore to get 30g of platinum, which is too little, we are now processing 10 tons of platinum ore, and we can get 1 kilogram of platinum ore, can you imagine?" It's just ...... n

"6 tonnes of platinum per month, and now the world's annual production of platinum is about 140 tonnes, and our annual output will soon be reached." Kim Doona also gradually got used to the life of Xidaelu, and said with a smile as she stroked her hair.

Chen Yi only listened but did not speak, and especially observed the work of the Mexicans.

He won't do anything about soaking the entire mine until the liquid is added in large quantities. In this way, ordinary mining methods are crucial. Fortunately, in open-pit mining, there are two main things that people need to do, digging and transporting. Just like in the early days of open-pit mining on Earth, coal ash came out of the ground with two rubbings, and coal could be mined with pickaxes, shovels, and wheelbarrows.

Mexicans work very hard.

In order to control them, the red wolf simply slept in the mine.

And the best thing he could do against the Mexicans was to lash out.

With whips and iron rods, all the laziness peculiar to South Americans was smashed.

Yu Weichao was also worried about something going wrong before, but Red Wolf made a good suggestion.

"It's the workers who do the work. Disobedient is the slave! ”

This banner is now hung in the middle of the mine, and in many languages, it is painted all over the mine.

"You've turned Mexicans into slaves?"

"There are only a few." Yu Weichao said quietly:

"We have given Mexicans a hierarchy, and the average Mexican is level 3, with the same authority as indigenous officers, mainly driving all kinds of engineering equipment, and can command indigenous soldiers and indigenous workers who are present. Level 2 Mexicans only have the power of indigenous soldiers, and cannot command indigenous soldiers and indigenous workers, but they are allowed to drive construction machinery, live in the Xijiang walled city, and have Pakistan and Tu pick-up and drop-off, and have indigenous services for meals. But if you are disobedient and demoted to 1 by the overseer, then you only have the power of ordinary aborigines, who have to take trucks or tractors to and from the construction site, and cannot drive construction vehicles, but can only carry them on their shoulders and do some chores that cannot be done by machinery. Level 0 is the slave level, and it is assigned to the Mexican overseers of level 4 to use ......"

"Does it work?"

"Mexicans are very, very fond of abusing their fellow citizens, Brazilians are Honduras, Ecuadorians are more abusive to Mexicans." Yu Weichao smiled secretly, Xida Lu has more than 500 South American people, and in the continuous increase, how to make good use of them is the responsibility of the diamond-shaped office.

Chen Yi looked at the construction site in front of him, not knowing what he was thinking.

Li Changning seized the opportunity and asked softly, "Do you want to meet a few Mexicans?" ”

"See the soldiers of the Purification Jungle War first, and then decide." Chen Yi slowly turned around, looked in the direction of Mara City1 and asked, "How are they doing?" ”

"The Sectarian War, also known as the Temple War, was fierce, and most of the nobles in Mara City went to the front. The rest of the old, weak, sick and disabled rarely even go to the West Malaysia market. ”

"What about the boom in the market?"

"The middle-class citizens are here, but the number of consumers is still small."

Chen Yi straightened his shirt, returned to the jeep, and said, "Call Yin Sen Shen, Jin Doona, you accompany me to Mara City, and we will go to meet the elders of Mara City." ”

Kim Doona happily said yes and asked, "What is the purpose?" What to prepare? ”

"Prepare the paperwork, we're going to annex it."

Yu Weichao was taken aback, and hurriedly said: "Lord, the noble clan of Mara City...... Yes, it is the kind of noble spirit god, if they forcibly annex it, they will refuse to die. ”

"Oh, that's right." Chen Yi glared at him and said:

"Suggest it early next time, if I say it, it will become a promise."

"Huh?"

"Mobilize a team of members, I want to see how they fight back."
