Release that Witch

When the boehmite reaches the gem level, it will reflect the brilliant light due to the high fire color. At the same time, it has strong pleochroism and other discolored gemstones change from one color to another. It can At the same time, it reflects a variety of colors, the most notable is the red and green, it is no wonder that the locals will be named in the colorful. Before I heard Barry’s introduction, I didn’t think about it. When I saw it, Roland immediately thought of this stone.

In addition, when the diaspore is dehydrated, it will be transformed into corundum... and the gemstone of corundum is the famous ruby ​​and sapphire. The latter's reputation is more prominent than the former.

But what excites him is not the gem itself.

"What about the residue dug out of the mine?" After a long time, the prince closed the wooden box and asked excitedly.

"Do you mean... the gravel that was dug up when you opened the mine?"

"Yes, it's not just stones, mud is counted, how do you deal with these wastes?"

"After shipment, they are all piled up at the foot of the mountain." Denver didn't seem to understand the meaning of the prince asking about the matter. "His Highness, please rest assured that we have carefully screened these ores, either the texture is too bad, or it is mining. The process is broken and can no longer be polished into gems. For the screening process, it is the most experienced veteran of the family, and there is no possibility of omission."

"You are wrong," Roland smiled and shook his head. "Those things... are probably the real treasures."

"What?" Denver suddenly stopped, and the other people looked quite amazed, as if they could not connect the mud with the treasure.

But he did not explain this thing badly because this era is even more difficult for steelmaking, let alone refining elemental aluminum.

The main component of diaspore is alumina, and it has been discovered as a companion to bauxite. A high probability means that the aluminum is enriched in this area, and both soil and rock can be used as raw materials for aluminum smelting. As the most abundant metal element in the earth, aluminum reserves are higher than iron and are almost ubiquitous. In other words, if you dig a stone out of the ground, Lucia can also decompose a small amount of aluminum, but it is not worthwhile for industrial refining. Therefore, only the place where aluminum is enriched has the value of mining.

Like this cave in front of you.

Roland called Pei Luo alone and whispered, "How did the Kezhen family manage gem mines in the past two hundred years? I mean... how did the previous leaders pay for them?"

"I have found out from the books left over by Osmond Ryan that the way to pay is very simple, that is, the Kezhen family can choose the secondary gem of a box from the collected gemstones every year as a reward, and The way to measure wheat is basically the same.” Pei Luo explained, “The square box is almost the length and width of a palm, and the depth is half a palm. As long as the lid can be covered, how many pieces can be put in. Of course, the most rare gemstone must be turned over to Lord."

"That is, the two family collections he just sent me are not the best?"

"It's really the best in terms of texture. At this point he doesn't dare to lie to you, but you also know that the gems are always bigger and more expensive."

"You have also received his gift, right?" Roland looked at the eldest son of honeysuckle with interest.

"Oh..." The latter responded a little slyly. "Yes, Your Highness, I will give you the gems when I go back."

"Leave it, I don't care about this," the prince didn't think. "I'm just curious. Who will guarantee that this reward is true? What if the family secretly takes more during the mining process? Put the house in the sky, or you can't find it?"

"Every batch of ore is transported out of the hole and screening will be supervised, and even if the Kezhen family steals it, it will not be too obvious. This is a mutual checks and balances. They are afraid of being severely punished by the lord and the lord is also I can't find so many people who know the mine well," Pedroton paused. "Moreover, even if you put on your own people, who can guarantee that you won't steal it?"

"It turned out to be like this," Roland nodded. "Then continue to follow this rule. But except for the colorful stones, I will also dig out the gravel and mud. After I go back, I will formulate a preliminary collection plan for you. First follow the above requirements."

"His Highness, these muds... really precious than gems?"

"It depends on who's in the hand," the prince replied.

What is aluminum? Its use is endless. It is characterized by low density and corrosion resistance. It has propped up half of the industrial production sky and is an indispensable key material for aviation technology. It is true that aluminum smelting is a troublesome work. The electricity consumed by electrolysis equipment is also an astronomical figure for Wudongcheng, but with Lucia, it can always be accumulated. By then, some weapons and equipment that are no less than miracles in this era will also have hopes, such as large airships.

Roland intended to focus on the two iron mines, and it seems that the plan is now slightly adjusted.

......

After examining the remaining two minerals and a salt well, I returned to the castle and the sky was completely dark.

After dinner, Roland couldn't wait to take out the pen and paper and began planning the use of new resources.

The first is the steam engine.

Whether it is mine drainage, haulage or brine extraction from a salt well, the steam engine can double the efficiency. The Maple Leaf and Wild Rose family have now been destroyed. He plans to recruit a batch of skilled workers from the North Slope Mine, and then recruit a large number of employees in the Changge District to allow the two new iron mines to operate first. The ore can be hauled back to the border area for smelting. The gem mine needs to wait for Lucia to rush to the long song to check the content of aluminum in each tunnel to arrange the next mining direction.

Another focus is on salt wells.

In the case of Roland's envisioned situation, in addition to using steam engine to pump water to increase production, in order to get the white salt, the remaining work is to eliminate impurities. Taking into account the complex geological composition, he decided to take a tube of brine in each well and bring it back to the border area, and then handed it over to the chief alchemist Kemer Spoel to study the specific impurity removal steps. After the process was completed, the factory was set up on the spot. Produce salt on a large scale.

Of course, the salt industry, like food, should also be franchised by the City Hall. The salt wells of the elk and honeysuckle homes can be supported by the technical support provided by Dongcheng City, but the salt produced must be sold to the City Hall at the prescribed market price, and the benefits should not be sold privately to the outside. If you can get a lot of refined salt at a low price, it will undoubtedly open up a new business path for no winter city.

Roland hopes that all this can be formalized after the fall of the Tiefico regime. (To be continued.)
