In the Apennines, the conspiracy continues, and it never stops. Pen, fun, pavilion www. biquge。 As far away as Moa, Wilts, according to Marin's instructions, successfully found laterite nickel ore.

Wiltz and his entourage, in order to find the exact location of Moa, spent a full month wandering to the northeastern coastal area of Cuba. After repeatedly comparing the coastline and landing to find the lake described by Marin, the location of Moa was finally determined.

Fortunately, the Taíno people in Cuba were very friendly, and after seeing Wilts and his party, they did not shoot directly with their bows. Wiltz was also a man with many years of work experience, and he was able to win the favor of the locals by giving gifts such as salt and bread at the right time.

The Tylenol people are gentle and hospitable, and Wiltz knows how to use small things to bring people closer. As a result, Wiltz quickly established himself in the Moa area. With the enthusiastic help of the Taíno people, Wiltz quickly led people to build a house to live in and settle down in the local area. Of course, the Taítans demanded that they be given salt on a regular basis.

In fact, Wiltz was also quite speechless about the lack of salt for the Taítanols. Why? The Taíno people live by the sea. Unfortunately, the Taíno people in Cuba are less civilized and can only fish in canoes or hunt with earthen bows and arrows. Of course, a little cassava is also grown, but the cultivation technique is extremely extensive. Although they live by the sea, the salt of the Taíno people has to be brave enough to drive a canoe to the Yucatan Peninsula in Mexico and exchange it with the Mexican Indians. Mexicans know how to use clay pots to cook salt, but Mexicans can't teach the Taínos, otherwise, how can they exchange goods with the Taínos?

But driving a canoe to the Yucatan Peninsula to exchange table salt is a journey to death. The canoe is too small, and if the sea is angry, there is no need for a big storm, and a slightly larger small storm can swallow the canoe. Therefore, going to the Yucatan Peninsula to buy salt from the Mayans was very expensive and often cost people's lives.

As a result, a dozen or so tribes near Moa met together to inform Wiltz that Wiltz could settle and "dig stones" in the area, provided that he was provided with enough salt each year, and that he would get help from the locals. Of course, salt is not for nothing, and the locals will also give their game or cassava in exchange. It's just that the price should be cheaper, preferably the same as the Mayans in the Yucatan. It should be noted that those brave people who rowed canoes to the Yucatan Peninsula to exchange salt often increased the price of salt several times after selling it back to Cuba. After all, that's what they paid for with their lives.

Locals use cassava as a reference for food and trade, and of course, shellfish currency. However, it is unlikely that outsiders will recognize the shell currency. For example, when trading with Mexicans, the Mexican currency is mostly based on cocoa beans. When the currencies of the two sides are not at the same pace, cassava and oats, which can be used as food, become important references.

In the Yucatan Peninsula, one pound of salt is exchanged for five pounds of cassava. But in Cuba, one pound of salt can be exchanged for more than 20 pounds of cassava. So, the local chieftain demanded that if Wilts could provide them with a large amount of salt for five pounds of cassava for one pound of salt, then he would have strong support from the locals for all his local activities, except killing.

Wiltz knew that Cape Breton Island would provide Cuba with a large amount of salt, so he agreed without hesitation. Wiltz also promised to provide the locals with iron farming tools and bows and arrows to facilitate farming and hunting. In this way, both parties get along more pleasantly. If it weren't for Marin's repeated edicts, which strictly forbade colonists to have sex with local women, some immigrants might have gone to roll the sheets with local enthusiastic girls. Fortunately, the horrific legend of syphilis and Marin's harsh punishment frightened the boys.

After settling down, Wiltz began to lead the team in search of nickel ore. Although Marin gave a rough range, Marin's casual finger was a very large piece of territory. Therefore, Wiltz and others also broke their legs. Thankfully, Wiltz paid for his brown bread and hired a group of locals as guides, so he didn't worry about getting lost in the rainforest.

Although, Marin explained that he was looking for red soil. However, before it was developed, the island was full of dense jungles and lush meadows. If you want to find red soil, you have to pick up the grass and trees......

In this way, Wiltz searched for two weeks before finally finding the clay......

Fortunately, the clay is easy to recognize, otherwise, Wiltz would have to die of exhaustion. As soon as he found the red clay, Wiltz set up a stove and burned the collected red clay at high temperatures.

Sure enough, after the high temperature burns, the red clay changes color and turns into green nickel oxide. At the same time, it emits a pungent odor (SO2). After finally finding the nickel ore, Wiltz was very excited and immediately began to mine laterite nickel ore, and began to assemble the furnaces and pipes that had been put down from the ship, intending to calcinate laterite nickel ore on a large scale.

According to Marin's plan, Wiltz needs to calcine laterite nickel ore into green nickel oxide locally, and use desulfurization water towers to collect sulfur dioxide gas.

However, at the beginning of production, due to the rupture of the pipeline and the lack of attention of the construction personnel to the desulfurization work, the desulfurization system leaked. The leaking sulphur dioxide gas smoked people enough. Moreover, it also angered the nearby Taínos. As a result, the nearby Taíno demanded that Wiltz stop making this "terrible gas......

Wilts, who had no firm foothold, had no choice but to suspend production. Then he saw that the map Marin had given him indicated that there was an island called Great Inagua, not far from Moa. After much thought, Wiltz decided to relocate the production of calcined laterite nickel ore to the island of Great Inagua. He's here to mine, not to fight with the locals. If possible, it is better to live in peace.

Seeing that Wiltz no longer made that terrible gas (SO2), the Tylenol people stopped bothering Wilts.

After exploration by the crews of the ships assigned to Wilts, it was discovered that on the island of Great Inagua, about 100 kilometres from Moa, there was no population on the west coast. In addition, there are many trees on the island, which are suitable for cutting down for firewood and calcination of laterite nickel ore.

In this way, Wiltz separated mining and smelting in two places. Of course, it also avoided conflict with the local Taíno people of Moa. After the relocation of the refinery site, the local Taíno people in Moa also took the initiative to help dig laterite nickel ore.

On the west coast of Great Inagua, Wiltz directed artisans to rebuild the smelting system and perfect the water desulfurization system. The forge is isolated from air, but has a bellows-driven air inlet that allows oxygen to be fed in, which reacts with nickel sulfide to produce nickel oxide and sulfur dioxide.

Sulphur dioxide gas travels through the pipes and enters the sink and is absorbed by the water in the tank. Of course, because SO2 is not as soluble as SO3. Therefore, after a period of time, the water in the sink that absorbs SO2 will form a saturated sulfurous acid solution after absorbing enough SO2. At this point, the water in the sink can no longer absorb SO2. Then, the foul-smelling SO2 will overflow. Then, the workers present need to change the water in the sink in time.

The originally saturated sulphurous acid solution is poured into another container, and the workers use wooden sticks to stir it incessantly, so that enough oxygen can enter the solution and react naturally with the sulfurous acid to produce sulfuric acid.

It's just that this process is very inefficient. Even after a few weeks of stirring, only a small half of the sulfurous acid is converted to sulfuric acid.

Moreover, because of the volatilization of water vapor, SO2 gas will leak out, causing workers to inhale SO2 and endanger health. Therefore, Marin requires frequent changes of workers to avoid long-term inhalation of SO2 by a single person. In addition, for workers who are responsible for dangerous processes that make it easy to inhale SO2, Marlin prefers to use Uncle Black......

Of course, when activated charcoal is made later, Marin will make gas masks. That way, you don't have to risk anyone.

As for how to separate sulfuric acid and sulfurous acid? Don't be too simple. Just put the mixed solution in the air and let the water vapor evaporate. SO3 is infinitely soluble in water, and as long as there is water, SO3 will stay in water and will not escape easily. Unlike SO2, the ratio of its dissolved volume to water is 40 to 1. As water vapor volatilizes, SO2 gradually escapes. When the water is reduced to a certain level, the SO2 will almost escape. Then, the rest is the sulfuric acid with a higher concentration......
