Release that Witch Chapter 494: New natural resource

When Diasporite reaches gem level, it will refract brilliant light due to the extremely high fire color, and at the same time, it has strong polychromaticity. Unlike other color-changing gem, which changes from one monochrome to another, it is It can refract multiple colors at the same time, the most notable being red and green, and it is no wonder that the locals will be named colorful. I hadn't thought of it before listening to the introduction of Barov. When I saw it with my own eyes, Roland immediately thought of this kind of stone.

In addition, when Diasporite loses water, it will be transformed into corundum (mineral) ... and the gem grade of corundum (mineral) is the famous red gem and blue gem. Compared with the former, the latter has a more prominent reputation.

But it's not gem that excites him.

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

"Are you saying ... the gravel excavated when the mine was opened?"

"Yes, not just stones, but mud, how do you dispose of these wastes?"

"After being shipped out, it was dumped at the foot of the mountain," Denver didn't seem to understand the meaning of the prince asking about it, "His Royal Highness, please rest assured that we have carefully screened these ores, or they are too poor in texture or they are It broke during the mining process and can no longer be polished into gem. For the screening process, the most experienced veterans in the family are responsible for the omission of impossible.

"You are wrong," Roland shook his head with a smile, "Those things ... are probably the real treasures."

"What?" Denver froze for a moment, and the expressions of others seemed quite surprised, like how could they not associate mud with treasure.

But he couldn't explain this because it was enough steelmaking in this era, let alone refining simple aluminum.

The main component of Diasporite is alumina. At the same time, it was found as a by-product of aluminum ore. It has a great chance to mean that aluminum is enriched here, 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 a stone is dug out from the ground, Lucia can also decompose a trace amount of aluminum, but it is not cost-effective for industrial refining, so only the place where the aluminum element is enriched has the value of mining.

Like this cave in front of you.

Roland called Petrov aside alone and whispered, "How did the Kerian Family family manage gem mine in the past two hundred years? I mean ... how will feudal lord pay them in the past?"

"I checked from the account book left by Osmond Ryan. The way to pay is very simple. That is, the Kerian Family family can select one box of secondary gem from the collected gem each year as a reward and weigh wheat. The method is basically the same. "Petrov explained," the square box is almost one palm wide and half deep, as long as the lid can be closed and put in as many pieces as possible. Of course, the most rare gem must be turned in to feudal lord. "

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

"It's really the best in terms of texture. He doesn't dare lie to you at this point, but you also know that gem is always bigger and more expensive."

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

"Uh ..." The latter responded awkwardly, "Yes, Your Highness, I will give you gem when I return."

"Keep it, I don't care about it," said the prince, "I'm just curious, who will guarantee that the remuneration is true and correct? What if the family secretly takes more during the mining process? This Except for the fact that the mansion has been turned upside down, otherwise it can't be found at all? "

"Every batch of ore will be supervised when it is transported out of the cave and screening, and even if the Kerian Family family steals it, it will not be too obvious. This is a relationship of mutual checks and balances. They are afraid of being severely punished by feudal lord. feudal lord can't find so many people who know the mine well, "Petrov paused," Moreover, who can guarantee that they won't steal if they replace themselves? "

"So that's it," Roland nodded, "then continue to follow this rule. But in addition to five colored stone, I also want the gravel and mud that have been dug up. After I return, I will make a preliminary collection plan for you , First implement the above requirements. "

"Sir, these muds ... are they more precious than gem?"

"It depends on whose hands." The prince replied.

What is aluminum? Its uses are countless. Its low density and corrosion resistance support the half-sky of industrial production. It is also an essential key material for aviation technology. It is true that aluminum smelting is a troublesome task. The electricity consumed by electrolytic equipment is also an astronomical figure for Neverwinter City, but with Lucia, it can always accumulate a batch. By then, some weapon equipment that is no less than miracles in this era will also have hope, such as large airships.

Roland was originally intended to focus on the two iron ores. It seems that there are plans to make some adjustments now.

...

After returning to the castle after inspecting the remaining two minerals and one salt well, it was completely dark.

After dinner, Roland can't wait to pull out the pen and paper and start planning the new natural resource utilization plan.

First is steam engine.

Whether it is mining site drainage, haulage or salt well brine extraction, steam engine can double the efficiency. The Maple Leaf and Wild Rose families have now been destroyed. He plans to transfer a group of skilled workers from Northern Slope Mine, and then recruit a large number of hired workers in Longsong region, so that the two new iron ore can be operated first, and the ore can be hauled back to the border area for smelting. gem mine needs to wait for Lucia to rush to Longsong and check the content of aluminum in each tunnel to arrange the next mining direction.

Another focus is salt well.

It is close to the situation expected by Roland. In addition to using steam engine pumping to increase production, if you want to get white refined salt, the remaining work is to remove impurities. Considering the complexity of the geological composition, he decided to take a tube of brine from each well back to the marginal area, and hand it over to the chief alchemist Cam Schuire to study the specific impurity removal steps. After understanding the steps, a factory was set up on site to produce large-scale salt.

Of course, like the grain industry, the salt industry should also be franchised by City Hall. The salt well of Elk and Honeysuckle Family can obtain the technical support provided by Neverwinter City, but the refined salt produced must be sold to City Hall at the prescribed market price, and it is not allowed to sell to the outside world for gain. If a large amount of refined salt can be obtained at a low price, it will undoubtedly open up a new business path for Neverwinter City.

Roland hopes that all of this will come to normal after the Timothy regime collapses. (To be continued.)
