Chapter 223 (2/2)

Therefore, the method of smelting lead and tin from ore has existed for a long time.

As an alchemist proficient in metal smelting, David Addison naturally knew how to smelt lead and tin.

In fact, both lead and tin are smelted by pyrometallurgy, which is similar to ironmaking. And the stone bear for lead and tin purity is not much demand, so there is no need to refine.

The two metals are smelted out and then mixed in proportion to make muskets. This kind of thing is a very simple thing for Addison.

However, when smelting lead and tin, Dean also told Shixiong a good news, that is, the lead-zinc ore found in this lead-zinc mine contains not only lead, tin, zinc and other metals, but also a lot of copper, accompanied by a lot of silver.

This is a normal situation. It is very common for lead-zinc ore to be associated with copper and silver. In fact, the reason why lead was extracted in ancient times was to extract silver at the beginning. Lead was only an additional product of extracting silver.

Being able to find silver is naturally a good thing. Silver is still valuable at this time. It's good to reserve more silver.

”Fast horse can do that?” Asked the stone bear.

”No problem! That young man is very good. I'm very optimistic about him. I'm going to pass on my ability to him David Addison is not a fool. On the contrary, he has not only high IQ, but also high Eq. He knows the relationship between Kuaima and his boss, so he has no taboo to teach Kuaima what he knows.

Adrian knows it's impossible to leave in the near future. Since he can't leave here for the time being, he doesn't mind trading his knowledge for better living conditions in order to live a better life.

Obviously, his practice has been appreciated by the stone bear, and also achieved some of the goals of adien. At least now he can talk with his boss so casually, which is a great progress.

For this kind of careful thinking of Eddie, Shi Xiong won't take care of it. On the contrary, he supports it. No matter what, the four of them are outsiders. Maybe they will change their mind and stay here forever, but that is the future after all. Who dares to guarantee now?

Therefore, through adian, the young people in the tribe can learn more. This is what the stone bear most wants to see.

So after hearing this, the stone bear nodded with satisfaction, ”David, what kind of paper did your paper mill mainly produce before?”

”What paper? More, as long as the customer needs, we produce any paper. But newsprint is still the largest producer. There are two newspapers and a printing factory in our hometown. The paper produced by our family is mainly used by this printing factory to print newspapers. ”

”So your paper is mainly low-grade paper?”

Adrian nodded a little embarrassed. Newsprint is a kind of low-end paper, even in later generations.

”Do you know what the paper I made this time is mainly used for? It's used to make cigarettes. It requires a lot of paper. ”

”Chief, I don't know what your requirements are, but I know that the difference between the high-grade paper and the resistant paper is not in the papermaking process, but in the raw materials, additives and processing technology. Chief, tell me the raw material ratio and additives you need for this kind of paper, and I promise to make the paper that meets your requirements

Seeing that edian was so angry and sure, Shi Xiong thought about it and nodded his head.
