Wang Wenxun listened to her and asked with interest: "Specialty mineral soil? What kind of mineral is it?"
Wang Wenxun replied, "It's nickel ore. The radio station at the First Base shared information that nickel ore can be used to make cryogenic clothing. Our lord allowed us to mine the nickel ore and bring it here."
Nickel mines mainly trade with the First Base because they are not sure whether this food supplier actually exists, but the First Base definitely exists.
Using nickel ore, which is worthless to them, to exchange supplies with the First Base is their backup plan for this trip. Even if they can't find a food supplier, they can guarantee to exchange something with the First Base.
But unexpectedly, food suppliers were also interested in nickel ore.
"Nickel ore!" Qiao Xuejun continued to ask, "Did you bring it here? How much?"
Wang Wenxun didn't hide anything and told the truth with full sincerity: "Yes, it filled a truck, about 2 tons."
They only came with a small truck and had to bring people with them, which was almost 2 tons when fully loaded.
2 tons, 4,000 kilograms.
Qiao Xuejun nodded: "So what kind of food do you want to exchange? How much do you plan to exchange?"
She had heard Zhao Xian say before that with Haibao's professional equipment and technology, the conversion ratio of low-temperature steel and conventional nickel soil could reach 1:2.
2 tons of nickel soil can produce 2,000 kilograms of nickel iron.
When it is further processed into thin plates, there is a 20% loss, which is 1,600 kilograms of finished thin steel plates.
5 kilograms of steel plate can make a set of low-temperature clothing. Taking into account some losses, at least 300 sets of low-temperature clothing can be made!
It's worth a lot of money.
Qiao Xuejun calculated in his mind that the base now has 7,000 people, and less than 3,000 of them need to be involved in outdoor work. It is enough for the base to have 3,000 low-temperature clothing on hand.
Then they need a total of 20 tons of nickel ore.
If it were potatoes, she could get at least 2 million catties. To be honest, she would be willing to give 5 million catties. Because apart from anything else, she already has 70 million catties of inventory that can be cashed out.
Now they brought 2 tons, which means she can give 200,000 kilograms of potatoes.
Wang Wenxun cautiously probed, "We heard we have potatoes. Can we exchange them for 4,000 kilograms of potatoes?"
After Wang Wenxun finished speaking, his face turned red.
Four thousand kilograms of potatoes is also 2 tons, which is equivalent to exchanging one kilogram of soil for one kilogram of potatoes.
He felt that the price was a bit too high. After all, nickel soil was actually worthless.
Yes, it can be made into low-temperature clothing. But turning the mineral into clothing requires a lot of processing. Their nickel ore costs nothing.
Nickel soil is easy to dig. There is no need to dig wells in the mountains. It can be mined in the open air. After the surface layer of soil is dug away, the soil underneath is all this laterite nickel ore.
Just dig it.
After he finished speaking, he nervously watched Qiao Xuejun's expression. He thought, if Teacher Qiao didn't want to, he could lower the bar again.
Sure enough, Wang Wenxun saw the expert's incredible expression. Just as he was about to change his words and lower the price, he heard Qiao Xuejun ask, "Friend, how many people are there in your base?"
Wang Wenxun said: "Our base is a merger of two bases, with a total of about 2,500 people."
Qiao Xuejun raised an eyebrow: "For 2,500 people, 4,000 kilograms of potatoes are only enough for two or three days." This is based on the minimum share of 300g per person per day.
Wang Wenxun was stunned.
Yes, if everyone ate, it would last for two or three days, and if they saved, it could last for four or five days. However, their food was given priority to the main labor force, and the rest of the people had to eat moss and mutant fish and shrimp to fill their stomachs.
4,000 kilograms of potatoes is already a very large amount of supplies.
It’s very cost-effective to exchange it for soil.
Qiao Xuejun said directly, "I can give you 100 tons of potatoes. It's enough to last you for half a year. But I need someone to inspect the goods first to see the quality of the soil."
Wang Wenxun was incredulous, and the other team members around him also opened their eyes wide.
How many?!
100 tons?
Wang Wenxun asked stupidly, "Really? One, one hundred tons?"
It is 50 times less than the 4,000 kilograms he proposed.
Qiao Xuejun smiled friendly: "Yes, one hundred tons, 200,000 jin."
200,000 jin was worth it to her. Moreover, given the system's needs, providing more food would also be beneficial, allowing more people in the Fourth Base to survive.
She added: "Of course, this is based on the premise that there is no problem with your nickel soil. Once my people have inspected the goods, it will be fine."
Wang Wenxun was a little excited. Their ore had a very high nickel content. It was a ore field that had been successfully mined before the natural disaster. They were also very careful when mining, and the ore was entirely laterite nickel, without any ordinary soil mixed in.
So he is not afraid of testing.
200,000 jin! He couldn't even load it all in one truck!
Wang Wenxun immediately agreed, fearing she would regret it: "Sure, sure, we can check it right now! We can check it anytime, our truck is at the foot of the mountain!"
Qiao Xuejun picked up the intercom, found the department's daily on-call channel, and spoke to Director Lin of the Coordination Department. "Director Lin, could you please coordinate with the steel plant to have a technical engineer go down the mountain to collect a sample of laterite nickel ore and test its quality? See how long it will take, and send me the results when they're ready."
After making the arrangements, Qiao Xuejun said to Wu Haifan and Wang Wenxun, "Captain Wang will temporarily stay at our First Base for a while until the results come out."
Wu Haifan: "It just so happens that it's time for dinner. Let's eat first."
Wang Wenxun hurriedly said, "We all brought rations." In the doomsday era, food is precious and we can't just eat other people's food.
Qiao Xuejun smiled and said, "There are only six of you here. We at the First Base can handle it."
The production of the eight greenhouses, both old and new, at the first base is now very stable. We have a daily supply of vegetables, and even some left over for kimchi and snacks.
