Chapter 21 The lead and zinc mines of the base
Gao Pet and his grandfather negotiated the establishment of a company in Tongling to build four factories: refractory brick factory, coke factory, glass factory and cement factory. Tongling is an extremely mineral-rich area, in addition to glowstone, the need for coal, kaolin, quartz sand, clay, feldspar, lime and other cloth minerals are available, even the land with minerals has been bought, so it was agreed that these factories are built in Tongling. The main forces of the Su family came over and recruited some helpers in Tongling. Gao's grandfather and second uncle bought a large house, and it seems that there are signs of a protracted war in Tongling for a long time.
The construction of the factory, the drawings of the factory and the kiln, and the related craftsmanship were given to their grandfather, and the construction of the mine and the factory was being carried out in an orderly manner. There is still some time to go into production.
In addition to building factories and mines, Gao Zhong was busy with army building and training. Gao Pet sometimes feels very painful, can't finish things, every day is not white or black, and there is always not enough time.
At night, in addition to drawing pictures and making plans, he also takes care of his own martial arts cultivation, and communicates with his heart and dantian every day, hoping that his luck will explode again, and he can control his internal strength that grows day by day. When chatting with Guan Yu and them that day, this person's internal strength broke out like crazy, and he never moved again, and Gao Pet did not respond when he greeted him. Gao Zhong can only do meditation every night, carry out imaginary training, clean up his mind, and hope that the light in his heart will be lit.
Gao Pet thought about the lead-zinc ore and sphalerite sent by Fuber in the first few days, and the lead and zinc were all very useful things in Gao Pet's plan, lead bullets, printed lead movable type, and corrosion-resistant "navy brass" should also use it. In particular, his sulfuric acid plant uses a lot of lead.
Although copper sulfate can be directly produced with sulfuric acid, a small amount of production is possible, but more is not possible. I want to use pyrite to produce sulfuric acid, but the catalyst vanadium pentoxide cannot be found for a while, so I can only use the lead chamber method to produce sulfuric acid.
Zinc is mainly used for brass, lithopone, white zinc powder, and insurance powder (sodium dithionite) for the production of pulp, textiles, and food. To make this insurance powder, zinc should be used as an intermediate.
Now that there is a mine, the plan of high-quality lead and zinc smelting has also been advanced. Gao Pet led people to the base.
Someone was called for the helper who had last discovered the ore, and this man looked to be nearly forty years old, but he was actually thirty-three years old, and he looked old at that time. It turned out that this person was a wok-hu who used to refine alum in Bianjing, and his family escaped after Kaifeng City was occupied by Jin soldiers and came to Tongling. Because I used to go out to look for minerals and know a lot of minerals. The gang found the ore during their work at the base, and although they didn't know what it was, they felt that it was a mineral that was of great use, so they handed it over to the supervisor.
"What's your name, Fan Wenyao? Okay, you can do things by my side from now on. Gao Zhong saw that this person had a certain amount of experience, and he was clever, he had read books for a few years, and he thought that he needed to build a laboratory, and he also needed a group of people to help him, and his two younger brothers were still young, and the legendary madman didn't know when he came to Tongling, so he asked this person over.
When Fan Wenyao heard that he was overjoyed, he hurriedly shook his head and thanked him, and followed behind Gao Chong.
When we arrived at the place where the ore was found, the trees here had been cleared, and wooden huts and grass houses were being built. Some of the ore that has been cleared from the ground can also be seen. It was not easy to find a good base, the place is large, there is water, and it is isolated on three sides, which is conducive to defense and closure. Gao Zhong wants to see if the back of the mountain is a mining area, if so, there is no need to move it for a few years for the time being, and in a few years, this base may have a better place.
"Let's go to the back of the mountain together to see if there is still this ore." I remember that the lead-zinc mine here was still very large.
Over the mountain, there is a small ravine and a small stream of mountains and water. Gao Zhong took a small hammer in his hand, knocked on the east and west, and the others also scattered to find it. It's a bit of a geological work.
In most places, the vegetation is thicker and there are fewer exposed rocks, so Gao Pet and his party walked down the ditch, two-thirds of the way, and the lower part was a valley with many rocks and cliffs. Fan Wenyao found colored stones on the edge of a sunken stone cave.
"Found it, young master, found it, here!" Fan Wenyao shouted excitedly, this guy, he still has experience, and several people ran over at once.
But I saw that the gangue was dotted with this colored ore, more of which was lead-gray ore, and when I knocked down a few pieces, it was heavier to start, and one was heavier than two ordinary stones. There is also a quartz vein mine that is one rub wide and three feet high on the side of the gangue stone.
This place is a figure-of-eight flare-shaped, which is suitable for building a smelter. The waste gangue from the mine can really be in the deep ditch below, which is a better mine.
"Dazhu, you go and call Fu Bo over, let him bring a few people, and say that our Gao family is going to open a mine here, and discuss the construction of a factory on the spot." Dazhu went, and a few people from Gao Pet were on the side to see if they had anything to find. Gao Pet sat on the stone and thought about the factory and production process.
The efficiency of mining is so low that the ore is manually chiseled out of the veins piece by piece. Although Gao Zhong had a black powder, that black powder was only enough to make ballista shells in his army. There is so little fire. The kapok used to replace black powder with smokeless gunpowder nitrocellulose is only introduced in a small amount in Guangdong. To make potassium nitrate, it is not as convenient as directly producing nitroglycerin or TNT from explosives. The manufacture of various mining and beneficiation equipment, various machinery, etc., three aspects, one is power, there are several options for power: one is the internal combustion engine, but the manufacturing and processing of the internal combustion engine, gasoline and diesel are a grand project, the electric motor, although it is simple, but the supporting facilities of the power plant and the power grid are very complex and huge, so electricity can only be a long-term plan, and the other is the steam engine. The steam engine is simple and convenient, just a boiler plus a set of four-way reversing control valves and a crankshaft linkage mechanism. A factory can use a set of boilers and pipe networks, which is equivalent to the power grid of Gao Pet's previous life. With this power, the rest is the mechanical problem and the machining problem of the machine, which is the machine tool equipment of the basic industry.
In this world, in addition to the basic application of casting technology and the technology of the previous life, there is not much gap, the rest is just hand-made some small objects, the performance of materials, dimensional accuracy is a problem, there is no manufacturing plate rolling mill, wire rod drawing equipment, seamless tube three-shaft rolling mill. Gao Pet has three heads and six arms, no matter how powerful he is, he doesn't have this time. Gao Pet needs a group of people who have mastered certain skills to help him complete it.
The basic school of the Gao family has been opened, and the textbooks compiled by Gao Pet are used, especially this mathematics, physics and chemistry are basically a simplified version of the junior high school in the previous life, and Gao Pet only has one or two classes every few days. Gao Pet is too busy.
"Young Master, are you looking for me?" Fauber and five or six others had arrived.
"Faber is like this, the one you got me is a lead-zinc mine, I found it here, and I'm going to open it out. You remember to call them over. ”
As Fauber beckoned, several other people gathered around.
"Look, this is the vein point, how to develop it, you need professional personnel to sum it up."
"Besides, you can give me a copy of the topographic map of this place tomorrow, and I will make a layout map of the smelter."
Because the smelting of lead and zinc in addition to the early beneficiation and concentrate treatment, it also needs to be sintered first, and then the blast furnace smelts the crude lead, and the slag that comes out enters the reverberatory furnace to smelt zinc in a reducing atmosphere, and the zinc should be condensed out from the exhaust gas, and a part of the waste slag is selected to enter the blast furnace for re-smelting, and the other is discarded. There are other precious metals such as gold, silver or selenium, strontium and other elements in general ores, but they have not been refined by the current technology. Let's just say that this lead, gold, silver and copper are often enriched in lead, but without electricity can not be electrolyzed, these precious metals can only be wasted in it, and later there is electricity, and then it will be recycled in it.
During this time, no one else made any major discoveries.
This high favor arranges all kinds of things. Let Fauber handle it here.
