Long before the war with Denmark, Marin was willing to help Sweden develop the copper mines of Failon. Because, Marin knew that Sweden had no source www.biquge.info of revenue. It would not be a matter if Lübeck and his own patronage were alone.

Therefore, Marin has long been with old Sten. Stuure talked about helping to develop Failun's mega copper mine with his own manpower and equipment. The gains obtained, five or five to half. However, the investment in the development of copper mines is all from Marin.

Actually, old Sten. Sturley didn't realize that the Faylon Copper Mine was a very large copper mine, but thought it was just an ordinary copper mine. Therefore, I feel a little embarrassed about the halves requested by Marin, and I plan to collect only taxes.

Traditionally, the official European tax standard for precious metal deposits such as gold, silver, and copper is 10% to 20%. Marin intends to give half of the proceeds to the Swedish authorities, which is naturally tax-free. In this way, Marlin is equivalent to taking 30% less profit. However, Sweden was financed in disguise. So that Sweden has the financial strength to deal with possible Danish retaliation.

You know, Sweden has a high latitude, and only the southern part of the country is suitable for a little agriculture. As for the northern regions, especially north of the Arctic Circle, the Swedes have not developed them at all. In the northern region, only the Sami live together.

In such a situation, Sweden has little source of revenue. Therefore, Sweden looks much bigger than Denmark, but its finances cannot catch up with Denmark.

Even before the Quadruple Coalition attacked Denmark, the southern coast of Sweden, which was suitable for agriculture and trade, was under the control of the Danes.

Originally, Sweden was not Denmark's opponent until the Faylon copper mine was greatly developed, and Sweden had enough financial resources to organize an army to compete with Denmark. The world-famous Gustav II would not have been able to participate in Germany's "Thirty Years' War" if it were not supported by the huge profits from the French copper mines. After all, Sweden wants agriculture without agriculture, trade without trade, almost nothing. Without the support of the Farrenon Copper Mine, Sweden's finances would be almost nothing......

Now Sweden, even if it has taken back the southern regions from Denmark. However, the financial situation remains poor. Although there is some iron ore mining and smelting, it is not large in scale and not very profitable. There is more wood, but it is mostly pine, and there is less oak. Pine does not sell as well as oak and is generally used to make furniture or to extract rosin. Of course, when building ships, decks and masts can also be made of pine. Mainly, oak is resistant to seawater corrosion, while pine is not seawater resistant and can only be used to create parts above the horizon that do not come into contact with seawater.

Long before returning from Copenhagen, Marin and the elder Sten. Sturley signed a written agreement that Marin would send someone to develop the Fayelon copper mine, with half of the proceeds going to the Swedish authorities. At the same time, the operation of copper mines is exempt from taxes. Because, the mining tax is included in that half of the income......

In addition, the Swedish authorities are not allowed to interfere in the operation of the Fayilun copper mine. In this way, Marin would be able to control the operation and sale of the Failon copper mine. Of course, if the Swedish government needs to purchase copper, Marin must supply it, and it must be supplied at a preferential price.

Marin had already sent Kohler to the south of Austria to recruit engineers for the start and smelting of copper mines. Austria is located at the foot of the Alps and has a lot of copper and silver mines. Therefore, there are many craftsmen related here. The southern part of Germany has always been a relatively developed region of European handicrafts. The handicraft industry and mining industry here are relatively developed. Bohemia and Austria have always been important sources of precious metals in Europe. The level of craftsmen here is also very high.

Moreover, in Austria, Maximilian I mortgaged the Tyrolean copper mine, the largest copper mine in Europe at this time, to the richest man in the HRE, Jacob. Fugger.

At this time, the price of copper in Europe is very expensive. By the nature of a businessman, Jacob. Fugger believes that the European copper price is not high enough. And the price of copper is not going up because copper production is too high. So, the first tyrant of the HRE, Jacob. Fugger, closed part of the mine, reducing production at the Tyrolean copper mine. In this way, the supply of copper is less, and the price will naturally rise.

However, as a result, some of the engineers and miners of the Tyrolean copper mines lost their jobs......

Taking advantage of this opportunity, Kohler sent people from the past to directly recruit those unemployed engineers with high salaries. In addition, some experienced miners were recruited to act as foremen and masters to go to the Fayilun copper mine to guide the Swedes in mining...... After all, the job of mining also requires the leadership and guidance of experienced miners......

Of course, mining is not that simple. Not only engineers and miners, but also smelting equipment are needed to turn copper ore into copper.

To this end, Marin also built a blast furnace of the oldest earth, which was used for copper smelting. The blast furnace "designed" by Marin is a simple blast furnace built in the "big steelmaking" period erected in the back mountain of his hometown in his previous life, with a simple structure and a small footprint. It is more versatile, not only can make steel, but also smelt non-ferrous metals such as copper. It's just that after the end of the "Great Steelmaking", this blast furnace was abandoned in the back mountain and became a scenic spot. When Ma Lin was a child, he often went to play on the bare top of the back mountain, so he naturally remembered the structure of the blast furnace and often went to play with the bellows of the drum furnace.

However, this kind of manual blast furnace, which looked extremely backward in the eyes of Marin and later generations, was a "high-end equipment" in Europe in this era...... It is used to smelt copper, and it works very well......

Sweden doesn't have anything else, but there is a lot of wood, and it is very convenient to burn charcoal. At that time, it is very convenient to use charcoal as a reducing agent in a blast furnace.

The only inconvenience is probably the traffic problem. Sweden is a relatively late developed area, and there are relatively few Roman roads. Moreover, it is said that the Failun region, which is located in the center of Sweden, has mountains and rivers...... The bad is bad because there are mountains and rivers...... Because, it is difficult to build roads......

Therefore, no one has discovered and developed the copper mine in Fayilun for a long time. Only in the coastal plain are Sweden more densely populated.

Therefore, it is also a big trouble to develop the Fayilun copper mine alone and not solve the transportation problem......

But whatever he is, as long as a large number of blast furnaces are erected on the spot in the Fayilun area to smelt copper, even if the transportation cost is high, it is nothing. Because, copper is also considered a precious metal in Europe at this time, and it is expensive......

According to the intelligence sent back by the men sent to Sweden, the nearest city to the Failon region is the eastern Swedish port of Gävle, which is only a few dozen kilometers away from Failun. However, it is this area of dozens of kilometers, full of mountains and lakes. It seems that it is not easy to open up a road from Fayilun to Gävle......

However, as long as this road is made, the development of the Fayilun copper mine will be easy. Because of the blast furnace and a group of highly skilled craftsmen to direct the rational mining of the mine. It is certain that the copper output of the Fayilun copper mine in the future will definitely not be low. As long as the road is clear, it can be transported to Gävle as soon as possible, and it can be loaded directly on a ship to East Friesland. Whether it's for casting cannons or other functions, it's a very good choice.

Moreover, if you sell it, the profit is also very considerable. After all, the price of copper in Europe is so expensive now......

Although, it may be cheaper to buy copper from India. But the problem is that the cycle to India is too long, and it takes nearly two years to run a round trip. If you need copper urgently, you may not be able to wait. This is also an important reason why Marlin has a process to add a process to the fertilizer processing plant to collect nitrate.

Moreover, ocean transportation is not very safe. If the ship carrying copper is caught in a strong storm and unfortunately sinks, it will be dumbfounded......

Therefore, it is necessary to develop a large copper mine in Europe. In this way, you can also ensure that you will not have a shortage of copper. Even if there is an accident on the copper ship to India, there will be no major problems.
