Any mine has a fatal disadvantage, that is, the treatment of tailings. For example, the iron ore we are here now.

You should know that mining and iron smelting will produce a large amount of residue. Although these residues still contain a lot of useful value.

However, the current technological means cannot be completely refined. Or even if it can be refined, the cost is too high.

However, Yuanyuan's idea was unique. He did not try to refine these slags, but turned them into building materials.

For example, cement, foam bricks and other things.

When Mei Ting just saw this plan, she didn't believe it. She had a certain understanding of the mine. The issue of tailings is basically a big problem for all mines in China.

There is no way to use it and there is no place to fill it in, and it eventually becomes a major murderer who destroys and pollutes the environment.

Many scientific research institutions are trying to solve this problem, but after so many years, they have not developed a practical solution.

If this round fate can really solve this problem, the actual significance it produces is definitely greater than the economic value.

Although most of the iron ore in Junken City is purchased from abroad, it still deals with several mines within the Corps.

Tailings are also their most troublesome problem. If this problem can be solved, not only can the environmental problems be completely solved, but they can also turn waste into treasure.

So, no matter whether this Yuanyuan is a liar or a master, she felt it was necessary to go and inspect it in person.

The mine where Mei Ting went was Jinshan Mining of the Second Division, which is a non-ferrous metal mine and one of the important raw material bases of the Military Reclamation City.

The mine manager's name is An Tianleng, who is not the second generation of the Corps, but he volunteered to work at XJ after graduating from Anhui University of Mining and Technology.

The reason why Yuanyuan came here to do this project is because they were classmates. Otherwise, there would be so many mines in Anhui Province, so there was no need to travel so far.

After introducing each other, Yuanyuan didn't say anything nonsense and took Mei Ting and the others to visit his workshop.

The workshop is very simple, it is actually a large shed made of asbestos tiles, with some crushers and other equipment inside.

Everyone in the walk was frowning. Can this workshop-like shed produce building materials?

Mei Ting didn't care about these things, but went directly to the finished product produced.

There are some foam bricks and cement placed there, with round edges, which are produced by crushing tailings and adding some raw materials.

Mei Tingrao looked at these products with interest and asked Yuanyuan to experiment with the performance of these products on the spot.

Yuanyuan started to hit the foam bricks with a sledgehammer. Not to mention, these light-weight foam bricks, both in terms of hardness and compression resistance, perfectly crush the traditional red bricks.

Everyone started to be surprised, it was simply incredible.

Then there is the experiment of cement, solidification speed, adhesion, and oxidation speed. The results are also surprising.

Mei Ting asked with a serious expression: "Why do you still need to run so far to experiment with such things? Is there no support in the local area?"

Yuanyuan smiled bitterly, then pointed to a scar at the corner of her eyes:

"This is what I left in my hometown. Because these things have had a great impact on the traditional building materials industry, they have touched some people's cakes, so they will try every means to stop them, or even attack them personally."

Mei Ting was silent. How could she not know about these things...
