Wiltz operates strictly in accordance with the "Guidelines for the Treatment of Laterite Nickel Ores" prepared by Marin to obtain large amounts of nickel oxide and sulfuric acid.

After nickel oxide is produced, it will be shipped to Cape Breton Island and further refined into nickel metal. Then, when smelting stainless steel, it will be added to ferrochrome alloy, and re-melted in a reflector, and further remove impurities.

Of course, nickel metal can also be mixed with copper and become copper that pretends to be silver. For Marin, who is good at counterfeiting coins, copper is definitely the best for minting counterfeiting coins...

As for sulfuric acid, it has a wide range of uses. First of all, it can be used to make copper sulfate and zinc sulfate - both of which are easy to obtain simple pesticides, which can greatly reduce the disease and pests of crops. Although it is not as toxic as chemical pesticides of later generations and have good effects, it is not as harmful as highly toxic pesticides such as cyanide in later generations.

For Marin, copper sulfate, zinc sulfate, lithosulfide mixtures and plant pesticides (mainly pyrethrum solutions), these are simple and easy-to-get pesticides. Moreover, because copper sulfate and zinc sulfate produce greater yields than pyrethrum, they can become mainstream pesticides.

In addition, sulfuric acid can also be used to make nitric acid, promote the development of chemical science, and even allow Marin to produce nitrosilicate cotton (smokeless gunpowder).

There is another purpose, which Marin thought by chance - that is, it can be used to make optical glass...

Quartz sand, the raw material for producing glass, often contains various impurities. Among them, the impurity that affects the performance of the glass is iron ions.

If iron ions exist, the glass will turn green, affect the light transmittance and reduce the quality of the glass. The Venetians came up with a method to neutralize iron ions with manganese ore, which reduced the greenness of the glass. However, glass treated with this method has good light transmittance early. However, over time, the glass will appear purple. Moreover, this physical "decolorization" method will reduce the "transmittance" of light, so it is not suitable for optical glass.

In his previous life, Marin once saw such a way to make optical glass - that is, pickling quartz sand...

The so-called pickling quartz sand is to use sulfuric acid or hydrochloric acid, or even water regia to soak the quartz sand powder to remove impurities in the quartz sand.

Quartz sand is insoluble in acid, but iron ions, including some other metal ions, are basically dissolved in acid. After pickling, the iron ions are dissolved and dissolved in the acid solution. In this way, the iron ions in the quartz sand are suppressed very low.

Moreover, all kinds of other mixed metal ions are also washed away by acid. The glass made of this pure quartz sand has high purity and strong light transmission.

What are these optical glasses used for? Nonsense, of course they are used to make telescopes...

Now, the telescope used by Marin, the army model can only see things within 5 kilometers, and the ones further away are directly blurred. It is also said that green glass at sea, which affects the effect of the telescope.

If you clean powdered quartz sand with sulfuric acid, the content of iron ions in the quartz sand will be reduced to the maximum extent possible. Of course, the key point is that the quartz sand needs to be finely ground, so that the iron ions wrapped in quartz sand can be fully avoided from being picked up. Of course, even if the ground is very broken, it is difficult to avoid the situation of small residues of iron ions. After all, even if you use steel mills to grind hard, the quartz sand cannot be ground into an atomic state. However, as long as you grind it into powder and pickled it again, it is more than enough to make advanced optical telescopes.

The telescope lenses made using this method will have the strongest translucency, comparable to the so-called "Russian military telescopes" in the future. In this way, it will be more convenient for spies and investigators to obtain enemy intelligence. In naval battles, the commander can more easily judge the number of artillery on enemy ships, and even estimate the relevant caliber...

In short, with sulfuric acid, quartz sand can be picked up and the best optical glass and the best telescope can be created to enhance the reconnaissance capabilities of Marin's reconnaissance personnel...

Therefore, Marin developed the nickel ore in Cuba, and the harvest was huge. Not to mention the nickel produced, it can be used to smelter stainless steel, or to make white copper, to counterfeit silver, and to make fake silver coins. If the European silver coins have high silver content and are relatively soft, it would be fine, but the white copper is too hard, and it can be distinguished. However, at this time, the European "silver coins" have a high copper content, resulting in a very high hardness. Therefore, it is actually more difficult to distinguish between counterfeit coins made from white copper...

Cuba's laterite nickel ore reserves are large, and it is in the million-ton grade. Marin is ready to flood Europe with fake silver coins made of white copper...

The by-product sulfuric acid brought about by processing laterite nickel ore is also widely used. Whether it is optical glass, pesticides such as copper sulfate and zinc sulfate, they are very practical for Marin.

You ask me how to produce copper sulfate and zinc sulfate? Copper is indeed difficult to dissolve in dilute sulfuric acid, but who fool told you to use copper and sulfuric acid to produce copper sulfate? Isn’t it okay to use high-purity copper ore? Whether it is copper oxide or other compounds, they are all dissolved in sulfuric acid... As for zinc sulfate, it is even simpler. The crude zinc ingot scraped off the wall of the cooling pipe of the smelting furnace is directly thrown into sulfuric acid...

Then, purify the crystals of copper sulfate and zinc sulfate, put them in an oil paper bag and seal them, and then transport them to various places as pesticides. When needed, unpack them directly, dissolve them in water in proportion, and spray them directly with a sprayer...

As for how to make a sprayer? This is a problem? Marin can copy an artificial sprayer that was carried on a farmer in a few minutes by later generations, which is professionally used for pesticide injections... After all, Marin's family in later generations used a bunch of artificial sprayers. When Marin was a child in his previous life, he often dismantled scrapped agricultural sprayers and played with it, so he should not be too familiar with its structure.

Wiltz found the laterite nickel ore. Although it was a great achievement, it could only be regarded as the first phase of completing the task...

In the second phase, Wilts needed to find the legendary chromite with a reserve of one million tons in the mountains near Moa...

However, at this stage, the difficulty is a bit too great. Because Marin can't tell what chromite ore looks like. Unlike laterite nickel ore, it's red in color. Just calcinate and see if there is SO2 flavor. Some are nickel sulfide, and those without taste are redite ore, which are simple and rough...

Because we don’t know what chromite looks like, we need to find this ore by ourselves. Anyway, we try any ore. If the iron is smelted, we have to try it out to see if it is easy to rust. If it is not easy to rust in a high-temperature water vapor environment, it is very likely that chromite is...

Therefore, it is much more difficult to find chromite ore than to find laterite nickel ore. Not only do you need to find iron ore that you don’t know what it looks like, but you also need to smel out the ore and use long-term testing of high-temperature water vapor to finally determine whether it is chromite ore.

And if chromite is found, then stainless steel can be released smoothly...

For this reason, Marin gave a high reward - he found that the nickel ore was just an ordinary non-hereditary jazz. When he discovered the chromite, he was directly upgraded to hereditary jazz and became a noble family... If he made great contributions, the baron could expect...
