PS: I'm very grateful to a lot of book friends who have seen the pirated version and come back to reward.,Lao Wu has always said that there is no anti-theft.,It's also because many people say that genuine reading is very stuck.。 But those who haven't rewarded after watching the pirated version, you should really reflect on it, should you reward and support?

Hematite, as a mineral raw material for ironmaking, is a by-mineral widely distributed in various rock formations, and has economic value worth mining, which must contain tens of millions of tons of hematite.

Jiang Hai understands that the reduction of hematite at high temperatures, 100 tons of hematite with 70 percent purity, after allowing iron smelting, no more than four percent, and 50 tons of iron.

The current price of a ton of iron is 1,300, which means that this vein is mined by itself, and at least 3,000 tons can be recovered.

Of course, if a pit only has 3,000 tons of hematite, then probably no one wants to spend this effort, it is laborious, dangerous, and there is no return in the event of an accident.

Therefore, those mining companies do not have enough mineral resources to explore, they will never take this risk, and this mine in Jianghai will be busy in vain if there is no 300,000 tons of hematite.

You must know that after the mining is done, it is the preliminary work, and the later stage includes transportation, including dredging the relationship, and it is inevitable that you will continue to work up and down, otherwise how can those red-eyed guys let you move a mountain of gold and silver at your own doorstep.

Say four million, that's the cost of nothing you have mined, but if you really mine the rich hematite, the cost will go up.

If you don't multiply your profits tenfold and hundredfold, it's really better not to wade into troubled waters.

Jiang Hai coordinated with the workers, and after a difficult trek, they finally drove the machine to Taohua Village.

This place where birds don't poop makes these miners and workers really feel like they are abroad, and Jiang Hai comforts them, so that the workers are willing to be wronged here.

But with a salary of 500 yuan a day, everyone is dissatisfied in their hearts.

Fortunately, this kind of survey work in the plains is not bad, if it is in the mountains. The danger is even greater.

The work will become more difficult.

In the first step, professional miners need to explore mineral resources, and generally this process takes ten days and half a month, and it is difficult to say what conclusions there are, Jiang Hai wears a bat hat. I can know where to start, these three mountains are some distance apart, the three mountains stretch for 3 kilometers, and the width is 500 meters, if you are so presumptuous to survey. Take some holes, set off guns, this comes and goes, not to mention the danger, and there is really no conclusion.

Jiang Hai knew that there was no mineral resources at all on this mountain, and all the hematite was concentrated in the geological layer below 50 meters.

The first priority was to dig a few mines and start the actual operation.

Jiang Hai pretended to be particularly lazy and ordered a worker to use industrial explosives to dig a few holes in the mountain and dig out the mine. Go straight underground.

The workers laughed at Jiang Hai who didn't understand, in that case, I am afraid that the mineral veins in this mountain would be blown up, but Jiang Hai continued to give orders, I don't care, follow what I say.

Come on, the workers feel that Jiang Hai is pretentious, and he is the boss, so he can do whatever he says, and then. Workers were arranged to take out industrial explosives, and four points were taken on the top of the hill to detonate the mountain locally.

Anything that involves industrial frying. The medicine has never been said to be 100% safe. After the explosives were planted, everyone was out of a safe enough distance.

The No. 1 blaster of the fluorite mining company organized the blasting mission, he retired from the army, this guy's grandfather participated in the War of Resistance against Japan, and his father participated in the War to Resist US Aggression and Aid Korea, although he did not go to the real battlefield. But guarding the border and chasing down drug lords is commonplace.

There's a lot of explosives to play with, and he hasn't had any problems with explosives in his hands. The location of the detonation is also accurate to the millimeter.

Yes, this vein is worth every inch of land, and the position deviation is a little bit, which means thousands of losses, but it is not child's play. Although the detonation site was chosen in a hurry today, he still tried his best to professionally avoid the occurrence of large-scale mine collapse, and the amount of explosives was not much, and he was only able to make a small hole in the mine.

With a bang, the first tipping point blasting is completed, and then the second, third, and fourth tipping points explode one after another.

The rolling rubble flew in all directions at once, and the smoke and dust immediately flooded the field of vision in front of him, and the thick smoke swept up into the sky, revealing a dragon-like pattern in the air.

There are many people who have seen this landscape blasting, and when the fog in front of them dissipates, Jiang Hai still feels shocked.

At this time, in the mine, four holes have been dug for one person to enter, and the investigation along this hole will continue, which is the next work of absenteeism.

In any case, Jiang Hai asked to continue the blasting, but the absentees did not agree, and they had their own professional ethics, and since they got paid, they had to be responsible for their work.

Speaking of which, the specific geological survey of the mining area is an important part of their work, and they need to conduct comparative research according to the geology of the detonated mining area and the previously available data to determine whether there are possible mineral deposits in the area.

With these initial determinations in place, it is time to select specific surveys at each site to determine what deposits will be based on the materials contained in the rocks and soils. Finally, the number of each survey point is combined, and the location where the deposit is most likely to be found, and further careful investigation is carried out, at which point work such as digging profile pits, drilling holes, and firing cannons will be useful.

But now, no matter what, you can't take the liberty of detonating, that's completely a layman's approach, and you will be laughed out of your big teeth when you say it!

No. 1 blaster, He Jingkun, also comforted Jiang Hai, telling him that this kind of resource exploration work is very tedious, requires patience and a strong sense of responsibility, after all, most ore deposits are buried underground, and it is definitely not an easy task to find out the deposits suitable for mining from a few meters or even tens of meters of soil and rock layers. In addition, soil and rocks contain a wide variety of mineral components, and how to analyze the desired results from these minerals requires great skill and experience, and most importantly, time.

Time, of course, Jiang Hai knows better what time means to himself. He knew where the hematite was, but he couldn't speed up the mining, which was a waste of time for him.

However, the demolition order he started today has undoubtedly improved the efficiency by at least three working days, and at the moment he can't get too involved, otherwise people will be suspicious.

What's worse, it violates the principle of doing things, and it is not impossible to pick and choose.

Simply, Jiang Hai went to the edge of the village, played a game of chess with the village chief Wang Tiemin, and exchanged feelings with him, the province is really developed in the future, this Wang Tiemin changed his hexagram with himself, and it would be bad to turn his face and not recognize people!
