Chapter 725: Change mining methods

Liu Yu said loudly: "Brother Dong, what are you doing?"
Gail's face was slightly ugly. It hadn't been like this yesterday. Such a thing happened after he had been away for such a long time.
So Gal shouted loudly, "Who did this?"
The hill in front is not high, and the is relatively gentle. Like many hills in inland Western Australia, it feels a little bald, with only low and sparse shrubs on the hill.
At the foot of the mountain, there is that big mine, a minecart consisting of several carriages, loaded with iron ore, slowly driving out of the mine to the gold processing factory not far away.
All this seems to be normal, and it is usually the same. On the of this mountain, there are two excavators working there. It seems that they have been excavating for a while.
As soon as Liu Yu saw this situation, a big question mark appeared in his mind, what they were preparing to do, could it be that they could not dig some treasure.
Wang Xudong guessed a little bit, so Wang Xudong looked at Gail beside him, waiting for Gail's answer. It can be seen from Gail's expression that he is temporarily unaware of it, and is angrily questioning whose idea was this and who ordered it to be done.
A person in charge rushed over and explained: "Boss, this is my idea. I want to try, can our gold mine be open-pit mining."
Gail was furious. This was a claim without his permission. He immediately said harshly: "You have been fired, please leave here immediately."
In Western countries, it is normal to be fired. This supervisor wanted to explain a few words. Seeing Gail's anger, he stopped saying anything and left with a sigh.
Wang Xudong looked at the two excavators in operation, thinking in his heart, the gold mining here has always wanted to mine mines. In fact, open-pit mining is more efficient and lower in cost. It is a very good one. Mining method.
Maybe try to change the mining method.
In the past, mine mining was chosen for confidentiality, because mine mining has a certain degree of secrecy. Gold ore is mined from the mine. If you don't enter the mine, no one knows the situation inside.
Now, Wang Xudong believes that there is no need to be so secretive. There are many things that don't need to be hidden. If someone is really jealous, it is useless for you to be secret. Some people will still worry about it.
If this is the case, then be open-pit mining with confidence and boldness. For others, it is estimated that it will be difficult to change the mining method from mine mining to open-pit mining. For Wang Xudong, it is very easy.
Wang Xudong stopped the supervisor and asked, "Why would you suddenly try open-pit mining?"
The supervisor saw that the boss stopped him, and was still amiable. Knowing that things would definitely turn around, maybe he would not be fired, so he immediately answered Wang Xudong's question seriously.
"Big boss, there was a geological team exploring the reserves and distribution of gold here. They concluded that there are thousands of tons of gold here, and the burial is extremely shallow, ranging from a dozen meters to 20 to 30 meters in depth. I think, Their exploration is not detailed enough. The reserves here are definitely more than one thousand tons. In addition, the burial depth may not be as deep. There are some gold mines whose burial depth is estimated to be less than ten meters. Because of this speculation, I want to try it. , Verify your guess."
This is a genius who can guess these things. Wang Xudong nodded and said: "Your guess is correct. Are you interested in staying? Try open-pit mining."
This supervisor is overjoyed, knowing that he will not be fired, and he will return to his post, and will continue to be the mining supervisor here.
"Yeah." He nodded happily and said loudly: "I am interested, very interested, I want to try open-pit mining of gold mines."
The largest gold mine in the world, its mining mode is open-pit mining. Furthermore, several large iron mines of Xudong Mining Group are also open-pit mining, and Xudong Mining Group has rich experience in open-pit mining.
In addition, more importantly, after the upgrade of the "God-level big mine owner" system, an improved version of the joint mining vehicle appeared in the system database.
It is equivalent to an upgraded version of the existing combined mining vehicle. It has advanced beneficiation functions and can directly select the finished ore from the original ore.
The original combined mining vehicle also has a beneficiation function, but only for the beneficiation of iron ore. Each iron ore of Xudong Mining Group has high grade and high concentration of iron ore, and there is no need to use the beneficiation function. Therefore, the joint mining truck manufactured by Shanhe Heavy Industry Group is a simplified version, which retains the functions of mining, crushing, screening and so on. The beneficiation function.
In the system database, the upgraded version of the combined mining vehicle has multiple models, divided into a, b, c and other models. Among them, the b-type combined mining vehicle has the functions of gold beneficiation and separation, and can be extracted from Gold is directly separated from the gold ore.
Such a good thing, Wang Xudong was going to make a try for the open-pit mining of gold here. He happened to meet this supervisor who was trying open-pit mining. Wang Xudong decided to change the mining mode here and mine from the original mine. Change to open-pit mining.
If there is no upgraded version of the gold mining vehicle, Wang Xudong does not expect to change the mining mode here, and has always been mining in mines. Now it is different. With such a mining vehicle, it is natural to change to open-pit mining.
Seeing that Wang Xudong really wanted to change the mining mode, Gaier was a little worried and said, "Wang, is this all right?"
Wang Xudong said confidently: "This is absolutely feasible, you can arrange it, and forget it today, starting tomorrow, change to open-pit mining mode."
After speaking, Wang Xudong added: "I was too rushed to explore here at the beginning, and the exploration was not comprehensive enough. It is estimated that the gold deposits here are really buried very shallow. You will know if you try it tomorrow."
Seeing Wang Xudong said this, Gale's worries were gone. In his mind, Wang Xudong was his "king", what Wang Xudong said, he would do it unconditionally.
Accompanied by Gail, Wang Xudong took a look at this big gold mine again, but he didn't enter the mine. The open-pit mining is about to be done soon. The mine will definitely be abandoned and there is no need to go in and see.
In the gold separation workshop, Wang Xudong saw a lot of newly separated gold. In the gold casting workshop, I saw newly cast gold ingots and bars.
Their golden appearance looks very likable, Wang Xudong is no exception, holding one of the gold bars, he looked at it with joy for a long time.
Since open-pit mining is required, the mining efficiency will definitely be greatly improved. A large amount of gold ore will be mined, and so many ore will be processed. Gale is worried whether the current scale of this gold mining processing plant will be a little smaller.
Wang Xudong laughed and told Gail that this factory does not need to be expanded. When the gold joint mining vehicle comes out, the gold separation workshop here will also be transformed into a melting and casting workshop.
There is an upgraded version of the combined gold mining vehicle. The gold is directly separated from the ore, no separation is required. Just smelt and cast them into standard gold bars and gold ingots.
There is such a thing!
After listening to Wang Xudong, Gael remembered the combined mining vehicle used in the No. 2 iron mine. It was a great tool for mining. Even if you haven't seen this gold mining vehicle, it is probably the same.
Gail was overjoyed, and after taking Wang Xudong to see the gold casting workshop, he went to the underground vault to see a large amount of gold.
There, there are already about five tons of gold, there are gold ingots, and there are also gold bars. The golden light looks very gratifying.
Gal said: "Wang, I have already contacted Hua Xia Bank, and their people will come and take away the gold in two or three days."
For large customers like Xudong Mining Group, if they want to deposit gold, they don’t need to send the gold to the bank. Instead, Hua Xia Bank will send people to the gold mine and go through the formalities on the spot and transfer the gold from here. Transport away.
After watching the big gold mine, it was already evening, and Wang Xudong returned to the small town. In the evening, everyone had a meal together, which was very rich.
Not only the senior managers of the No. 2 iron mine, but also the senior managers of the big gold mine, it took more than an hour for a meal to leave.
Returning to the villa where he was staying, Wang Xudong activated the "God-level big mine owner" system to regroup gold mines for this big gold mine.
When it was gathered in the past, considering the mining mode of mines, the gathered gold ore formed a one or two kilometer long vein, with burial depths ranging from 20 to 30 meters to 200 to 300 meters. Now, it is completely This is not necessary.
The gold ore re-assembled, all gathered in a large group, and concentrated under that hill. The surface layer was only covered with a layer of soil and sand ranging from several meters to more than ten meters.
As long as the layer covered by the surface is excavated, there are a lot of gold mines underneath, with grades ranging from a dozen grams/ton to several hundred grams/ton.
Wang Xudong can also increase the grade of the ore by 1%, which means that up to 10 kilograms of gold can be separated per ton of ore~EbookFREE.me~Wang Xudong did not do this. If it were all such high-grade gold ore, it would shock the world. , It’s better to keep a low profile. A grade of more than ten grams/ton is enough, not to mention that a small part of the ore also reaches a very high grade of several hundred grams/ton.
the next day.
In accordance with Wang Xudong's instructions, Gal arranged a large number of miners to start open-pit mining, starting from the bottom of the hillside, and a total of several excavators were starting to excavate.
For the time being, there is no gold mining truck, and it is possible to use conventional mining equipment. The efficiency of these excavators is not low. A large amount of soil and sand are excavated and transported away.
A few hours later, as it approached noon, they finally made an amazing discovery, and many people exclaimed.
At this time, Wang Xudong took an off-road vehicle into the big gold mine and stopped in front of this excavation area. When he got out of the car, Wang Xudong saw that there were several excavators working there. There were many people on the periphery, all craned their necks, and some even exclaimed in surprise!
…………
The first one is sent!
