After heavy sand processing, the gold is enriched and then refined in a furnace. After re-selecting the crude gold, it is best to use electrolysis to extract gold. Use sodium cyanide solution to dissolve the gold in the ore, and then extract the gold through electrolysis. With this refining method, the purity of gold can reach 99.9%. "Is this Thousand Pure Gold?" Huangshan said blankly, looking at the extracted yellow lump. "Yes, it's so simple to get such a big piece of pure gold." Han Kongque said with a smile. This piece of pure gold is as big as a human head and weighs more than one hundred kilograms. "This is more than one hundred kilograms, two hundred kilograms?" The golden demon was also a little dumbfounded. Gold sand and gold nuggets are definitely not the same concept! Although Thousand Pure Gold cannot be said to be pure gold, it is still amazing enough. Anyone can be surprised to get so much gold after just working for a few hours. It turns out that in the holy lake in the Tibetan area, what Han Kongque saw was the finished product, so he was not so happy about the harvest. But this time, he personally refined the crude gold. Looking at the beach with just a small pit, even though Han Peacock was used to seeing treasures, he couldn't help but feel excited at this time. "Don't move, you are risking your life, mercury is poisonous." Han Peacock immediately warned when he saw Huangshan and Jin Yao going crazy to collect gold sand. It¡¯s okay to collect gold sand, but it¡¯s not possible to use the tools he made to make gold, so Han Peacock immediately pulled them aside. The only drawback of the mercury amalgamation method is that it is poisonous. Just now, Han Peacock controlled a layer of water vapor to isolate the gold sand from the mercury. Otherwise, the mercury would volatilize, which could kill people. "The gold sand left here has a high gold content. We can directly smelt it into gold bars, which is easier to carry." Seeing that they were all motionless, Han Kongque said with a smile. ??????????????????????? They have nothing to do anyway, they just want to collect the gold here, and the happiest part of exploring treasure hunting is when it¡¯s harvested. Now looking at a golden beach, they naturally want to put them all away, and it is most convenient to turn them into gold bars. Han Kongque had encountered gold mines before, but he had not collected them himself. Instead, Wood Spirit and Jin Yao had done gold and silver processing, and Zhou Meiren was a professional, so the tools in the chaotic space were very comprehensive. "I'll go pick it out." Mu Ling was familiar with the tools for smelting gold, so she volunteered. ?? Han Peacock opened the portal to the chaotic space, and Mu Ling walked in. As long as it was the tool she chose, Han Peacock immediately created the space. A lot of tools were produced. Mu Ling looked at them and said: "I have seen all these equipments. Although they are a bit old, they are all good. You see, these are ultrasonic cleaning machines, various files, and polishing machines. The electroplating solution, the mold, the craft hammer, and here is the gold melting machine, the gold melting furnace, and here is the matching mold. We just need to pour the gold water into it. " Listening to Mu Ling's introduction, Han Peacock was very satisfied. Mu Ling works very carefully, and she can operate all these equipments. From this point of view, she is definitely a caring person. Gold bars do not require any manufacturing process or drawings. You only need to put thousands of pure gold into the gold melting machine to turn it into gold water, and then make some special marks, so there are no complicated process requirements. Han Peacock had to operate it himself, so Mu Ling had to explain the operation method of the gold melting machine to Han Peacock in detail. At this time, not only Han Peacock is interested, but Jin Yao and Huangshan are also very interested. After all, gold is common, but so much gold is definitely not common. The two of them were fumbling around with these devices. They had just heard Mu Ling talk about them, but they hadn't had time to operate them yet. But it¡¯s also simple. You just need to put the smelted gold lumps into the gold melting furnace, turn it into gold water, and then pour it into the gold bar mold, so it¡¯s still very fast. The only shortcoming is that this gold melting furnace is relatively small. These were originally used to make gold jewelry. Not much gold is melted each time, so making gold bars is a bit troublesome. This gold melting furnace can only melt more than 20 kilograms at a time, but you can't blame Zhou Meiren. Her family is a jewelry company, and there is no record of melting more than 20 kilograms at a time. How could she have thought that Han Peacock needed so much gold? What about melting? After getting ready for alchemy, Han Kongque tried to open a pot and put the gold into the gold melting furnace. It only took five minutes for the gold to turn into gold water. Then he put the gold water into the mold and cooled it into a liquid. A full twenty minutes passed with every gold bar. The golden sand turns into thousands of pure gold. The thousands of pure gold is put into the gold melting furnace and turned into gold water. The gold water is poured into the mold and cooled into gold bars. The whole process takes more than an hour. After you become proficient, you can smelt it onceAs the amount of gold sand increases, the speed increases, so every hour, they will harvest 24 to 5 kilograms of gold. The gold bars made by Han Peacock are all one kilogram, so you can harvest twenty-four or five gold bars each time. The four people panning for gold did not feel boring. They divided the labor and cooperated. Han Kongque smelted the gold sand into thousands of pure gold, Huangshan put the thousands of pure gold into the gold melting furnace for smelting, and the Golden Demon poured the gold water into the mold. After the gold water in the mold cools down, Mu Ling will collect the formed gold bars from the mold and rearrange the mold to prepare for the next production of gold bars. After a complete set of procedures, they were able to harvest more than 20 gold bars each time. I don¡¯t know how long they had been doing it, but they finally stopped. "I'm starving to death." I don't know how much time has passed now, but the golden sand next to me has not disappeared much, and Huangshan is shouting that I am hungry. "It's been more than ten hours. I'm really hungry. Let's stew venison today." Han Peacock glanced at the gold bars piled next to him. He had produced a lot of gold bars in more than ten hours. A rough estimate showed that it was almost three hundred kilograms. . "At this rate, we can produce five hundred kilograms of gold bars in one day." Mu Ling did the math and said a little stunned. "Five hundred kilograms? So it's one ton in two days?" Jin Yao also said in surprise. Huangshan laughed and said: "This piece of golden sand has not been consumed much. It seems that we are really going to spend the winter here." "Are you really planning to finish mining the golden sand here before leaving?" Han Peacock glanced at the three said an excited guy. "We have one thousandth of the share, how can we give up? We won't leave until we dig out all the gold here." Mu Ling said with a smile. Han Peacock shook his head helplessly, are these guys short of money now? "We want to leave some gold as a family heirloom." The golden demon said stupidly. Han Kongque could only say: "Okay, you can do whatever you want. How much is one thousandth? For a thousand tons of gold, you only get one ton each. Are you still afraid that I will ignore this of yours?" Gold?" "We don't have such thoughts, this is what you said." Jin Yao said seriously. "Yes, we are just enjoying the joy of the harvest." Huangshan said sanctimoniously. ?? Han Peacock simply ignored these guys. They were just refining gold and didn't have time to count them carefully. Now while he was eating, Han Kongque planned to count them one by one. The first time, there were twenty-three in total. On average, it took two minutes to count each one. Thinking of the golden sand not far away, but not sure how deep it was, Han Kongque felt helpless. It seemed that they really had to stay here for a while. After eating, they took a rest and then worked for another eight hours. It took eight hours to produce 250 gold bars. Excluding the daily rest time, it would be enough to produce 500 gold bars in one day. ??Looking at this speed, it seems very fast, but looking at the piece of golden sand, Han Peacock felt as if he had fallen into a pit. No matter what Han Kongque said, Jin Yao and Huang Shan, two guys who were so excited that they couldn't find the north, were determined to refine gold here. Therefore, no matter whether it is windy or rainy outside, they will continue to play with gold bars in this cave as always. It wasn¡¯t until a month later, with the help of the entire escort team, that they completed one stage of the alchemy journey. "If we really listen to you, we will stay here for a few years." Recently, Han Peacock was so numb when packing gold bars because there was so much gold sand in the gold bars. In the first two days, there was one ton of gold, then one ton a day, and then several tons a day. Just like that, the speed was not very fast. In the end, we had to mobilize forklifts to get the gold sand into the chaotic space, so that the guards in the chaotic space could With the help of all the team, a thousand tons of gold were smelted. If we follow the original plan, it will take more than 500 days to complete the one thousand tons of gold. Over 500 days, it will take almost two years. "Who would have thought there were so many?" Looking at the gold sand accumulated in the space, these gold sands have been deposited here for unknown number of years, but now they have been swept away by them. "There must be a super-rich gold mine upstream, otherwise there wouldn't be so much gold sand here." Zhou Meiren said. Han Kongque said: "Perhaps all the gold mines upstream were corroded by the snow and water, and they all turned into gold sand and appeared here." "Impossible, gold ore is not that easy to corrode. Besides, the gold content of the gold sand here is too high. Therefore, there must be natural gold mines upstream," Zhou Meiren said. ??The Korean Peacock has made so much noise in recent times, so naturally the family knows about it., and the one who is most interested is naturally Zhou Meiren. Nowadays, jewelry is not easy to sell, but gold has never been difficult to sell. It turns out that many of the gold bricks obtained by Han Kongque were antiques. Later, those obtained in Tibetan areas were simply gold statues, and some were simply gold plates, gold bowls, and gold cups. Naturally, these things cannot be melted to make gold jewelry. Therefore, the most excited person to discover the golden sand this time is Zhou Meiren, so that her Phoenix jewelry will really have no shortage of gold. (~^~)
