Reborn Regent of Ming Dynasty

If the income is less than one million silver a year, I really feel uncomfortable.

This trip is to solve troubles and problems, but he is not a mining expert, and there are a few people from the general office with him. Over the past year, the general office has recruited thousands of people and has expanded into a super Most of them, many of them came from Jiangnan, some of them had been mining in Jiangxi, and some of them were good hands. This time they came here, and they brought these people here.

"It needs to be reinforced here, and more wooden boards should be added."

"Add a ladder here, so that more people can go down."

"The drainage here is better, and I'm afraid there will be more mines coming out." [

These masters are not polite, they go down the well when they come up, and they are also experts in pointing out, but after they came up, they shook their heads at Zhang Shouren and said: "My lord, no matter how much you strive for perfection, it is of no great use. The little people know nothing better than here No matter how clever they are, they have already done a good job."

"Okay, let's watch the Ji sow gold come out again."

Although there were minor setbacks, fortunately Zhang Shouren was a man of firm will, and if he didn't go through all the procedures, he hadn't yet reached the point of despair.

When I arrived at the place where the gold was sifted, I saw a hundred strong men, each of whom was shirtless, with a dustpan in his hand, filled with crushed dust containing alluvial gold, and in places with downwind, they kept raising the soil. .

After lifting the soil, change hands again, continue picking, spreading, picking again, and finally pick out the large and small particles containing gold in the dustpan.

"My lord, I need to use something to crush these particles again, just like the ore was crushed before, and then sow and crush again. It takes several times before I can get gold."

"Actually, crushing is not troublesome, just keep smashing it. It's just that the broken gold is hidden in the earth and rocks. If it is sown heavily, the gold will fall out. If it is sown lightly, it will be tossed over and over again. It is still like a bird. Looking for a few grains of gold in ten catties of soil, many people have ruined their eyes."

Zhang Shouren wondered, "Why not wash with water?"

"Shui Tao?"

Everyone looked at each other in blank dismay, and those who followed were all good players, but no one had heard of this method of water scouring.

"My lord, I'm afraid that water washing will wash away all the placer gold and soil together."

"I don't know what tool to use?"

"I've never heard of it..."

Zhang Shouren couldn't help but laugh. Only then did he realize that China's mining industry was indeed relatively backward, especially that the Ming Dynasty was not as good as the former Song Dynasty in terms of mining industry, and had already lagged behind the West in terms of technology.

He ordered: "Find a bronze mirror and melt a layer of silver on it. How long will it take to heal?"

There are a lot of skilled craftsmen in the mine, someone did the math and said with a smile: "Half an hour is enough."

Zhang Shouren looked at Li Zhuoran, and the other party understood, nodded and said: "The subordinates will do it."

Half an hour later, a piece of silver-plated copper mirror was brought over. Although it was still very rough, it was still useful.

Find another place with turbulent water flow, pour a dustpan of sand on the mirror surface, the water will wash away the floating soil first, and then fiddle with it with your hands. Under the water surface and above the silver surface, you can clearly see the placer gold shining. glow. [

"This method will pollute the water quality, and a large amount of silt ore will enter the water. However, there is no way to do it. After the ore comes out, use the water pan method to get gold. Compared with the current skip sowing method, it is at least five times faster. above."

Zhang Shouren picked out a few grains of golden sand, feeling somewhat proud and confused.A few months later, this piece of green mountains and green waters will no longer exist.

However, at a time when the entire nation is in crisis, this price may have to be paid.
