Liu Yu said even louder: "Brother Dong, what are you doing?"

Gail's face was a little ugly, there was no such thing yesterday, and he had left for so much of the day, and such a thing happened. Pen % fun % Pavilion www.biquge.info

So Gail shouted, "Who did this?"

The hill ahead, not too high, has a gentle slope, and like many small hills in the interior of Western Australia, it has a bit of a bare feeling, with only low and sparse shrubs on the hill.

At the foot of the mountain, there was the big mine, a minecart composed of several wagons, loaded with iron ore, slowly driving out of the mine to the gold processing plant not far away.

All this seems to be normal, and it is usually like this, but it is abnormal on the slope of this mountain, there are actually two excavators working there, and it seems that they have been excavating for a while.

As soon as Liu Yu saw such a situation, a big question mark appeared in his mind, what were they preparing to do, could it be that they could not dig up some treasure.

Wang Xudong guessed a little, so Wang Xudong looked at Gail next to him, waiting for Gail's answer. It could be seen from Gail's expression that he was unaware for the time being, and was angrily questioning loudly whose idea it was, and who ordered him to do this.

A person who looked like a supervisor hurriedly ran over and explained, "Boss, this is my idea, I want to see if our gold mine here can be open pit mining." ”

Gail was furious, this was an unauthorized claim without his permission, and immediately said sharply: "You have been fired, please leave here immediately." ”

In Western countries, it is normal to be fired, and the supervisor wanted to defend himself, but when he saw that Gale was in a hurry, he didn't say anything anymore and left with a sigh.

Wang Xudong's eyes looked at the two excavators in operation, and thought to himself, the gold mining here has always wanted to carry out mine mining, in fact, open-pit mining is more efficient and cheaper, it is a very good way to mine.

Maybe try to change the way mining is done.

In the past, the choice of mining was just for the sake of secrecy, because there is a certain degree of secrecy in mining caves, and gold ore is mined from the mines, and no one knows the situation inside if they do not enter the mines.

Now, Wang Xudong thinks that there is no need to be so secretive, there is no need to hide many things, if someone is really red, it is useless for you to be secretive, and some people will still be worried.

In this case, it is fair and honest to carry out 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, but for Wang Xudong, it is very easy.

Wang Xudong stopped the supervisor and asked, "Why did you suddenly try open-pit mining?"

The supervisor saw that the big boss stopped him, and he was still pleasant, knowing that things must have taken a turn for the better, maybe he would not be fired, so he immediately answered Wang Xudong's question seriously.

"Big boss, when there was a geological team here to explore the reserves and distribution of gold, they came to the conclusion that there are thousands of tons of gold here, and the burial is extremely shallow, ranging from more than ten meters to twenty or thirty meters. I don't think they've been meticulous enough in their exploration, there are definitely more than a thousand tons of reserves here, and in addition, the depth of the burial may not be so deep, there are some gold mines, which are estimated to be buried at a depth of less than ten meters, because there is such speculation, I want to give it a try and test my guess. ”

This is a genius, he can actually guess these things, Wang Xudong nodded and said: "Your guess is estimated to be correct, are you interested in staying and trying open-pit mining." ”

The supervisor was overjoyed, knowing that he would not be fired, and that he would be reinstated and would be able to continue his role as mining supervisor here.

"Hmm. He nodded happily and said loudly: "I'm interested, very interested, I want to try open pit mining in gold mines." ”

The world's largest gold mine is mined in open pit mining. In addition, several large iron ore mines of Xudong Mining Group are also open-pit mining, and Xudong Mining Group has rich experience in open-pit mining.

In addition, and more importantly, after the upgrade of the "God-level Great Miner" system, an improved version of the combined mining vehicle appeared in the system database.

Equivalent to an upgraded version of the existing combined mining vehicle, it has advanced beneficiation function, which can directly separate the finished ore from the raw ore.

The original combined mining vehicle also had a beneficiation function, but only for the beneficiation of iron ore. The iron ore grade of each iron mine of Xudong Mining Group is high and highly enriched, and there is no need to use the beneficiation function, so the combined mining vehicle manufactured by Sunward Heavy Industry Group is a simplified version, which retains the functions of mining, crushing, screening and removes the beneficiation function.

In the system database, there are multiple models of the upgraded combined mining vehicle, which are divided into A, B, C and other models, among which the B combined mining vehicle, which has the function of gold beneficiation and separation, can directly separate the gold from the mined gold ore.

Wang Xudong was going to make such a good thing and try it out for open-pit gold mining here, but it happened that the supervisor was trying open-pit mining, so Wang Xudong decided to change the mining mode here, from the original mine mining to open-pit mining.

If there is no upgraded version of the gold mining vehicle, Wang Xudong is estimated that he will not change the mining mode here, and has been using the mine for mining, but 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, Gail said a little worriedly: "Wang, is this okay?"

Wang Xudong said confidently: "This is absolutely feasible, you go and arrange it, forget it today, and from tomorrow, change to the open-pit mining mode." ”

After speaking, Wang Xudong added: "When we were exploring here, it was too rushed, and the exploration was not comprehensive enough, and the gold ore layer here is estimated to be really shallow buried, so you will know if you try it tomorrow." ”

Seeing Wang Xudong say this, the worry in Gaier's heart was gone, in his mind, Wang Xudong was his "king", whatever Wang Xudong said, he did it unconditionally.

Accompanied by Gail, Wang Xudong took another look at this big gold mine, but he didn't enter the mine, and he was about to open it up, and the mine would definitely be abandoned, so he didn't need to go in again.

In the gold separation workshop, Wang Xudong saw a lot of freshly separated gold. In the gold casting workshop, you can see the newly melted gold ingots and gold bars.

Their golden appearance looks very likable, and Wang Xudong is no exception, holding one of the gold bars, and looking at it happily for a long time.

Since there will be open-pit mining, the mining efficiency will definitely be greatly improved, a large amount of gold ore will be mined, so much ore will have to be processed, Gail worries whether the scale of the gold processing plant will be a little smaller.

Wang Xudong laughed and told Gail that the factory did not need to be expanded, and when the gold combined mining truck came out, the gold separation workshop here would also be transformed into a melting and casting workshop.

There is an upgraded version of the Gold Combine Vehicle, where the gold is separated directly from the ore, no more separation, just smelt and cast them into standard gold bars and ingots.

And something like that!

After listening to Wang Xudong, Gail remembered the joint mining vehicle used in the No. 2 iron mine, which was a big weapon for mining, even if he hadn't seen this gold mining vehicle, it was estimated that it was about 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 were already about five tons of gold, gold ingots, and gold bars, and the gold was shining brightly, and it looked very pleasant.

Gail said: "Wang, we have already contacted Huaxia Bank, and their people will come over in two or three days to transport away the gold." ”

If a large customer like Xudong Mining Group wants to deposit gold, it is not necessary to send the gold to the bank on its own initiative, but Huaxia Bank will send someone to send a car to the gold mine, go through the procedures on the spot, and transport the gold from here.

After watching the big gold mine, it was already evening, and Wang Xudong returned to the town. In the evening, everyone had dinner together, which was very hearty.

There were not only a few high-level executives of the No. 2 iron mine, but also several senior managers of the big gold mine, and they ate for more than an hour before they left.

Returning to the villa where he lived, Wang Xudong started the "god-level big mine owner" system to regather gold mines for this big gold mine.

In the past, considering that it was a mining model, the gold ore formed a vein one or two kilometers long, and the burial depth ranged from 20 to 30 meters to 2 or 300 meters, but now, there is no need for this.

The gold ore regrouped, all in a large clump, enriched under that hill, covered with only a layer of earth and sand ranging from a few meters to a dozen meters.

As long as you dig out the layer covered by the surface, there is a large amount of gold underneath, with grades ranging from a dozen grams per tonne to hundreds of grams per tonne.

Wang Xudong can also raise the grade of ore to 1%, which means that up to 10 kilograms of gold can be separated per ton of ore. Wang Xudong did not do this, if it was all such high-grade gold ore, it would shock the world, it is better to keep a low profile, the grade of more than ten grams per ton is enough, not to mention, a small number of ores have reached hundreds of grams per tonne of extremely high grade.

The next day.

According to Wang Xudong's instructions, Gale 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 are no gold mining trucks, and it is possible to use conventional mining equipment, and the efficiency of these excavators is not low, and a large amount of soil and sand and gravel are dug up and transported away.

A few hours later, near noon, there was finally a startling discovery, and many people exclaimed.

At this time, Wang Xudong took an off-road vehicle and entered the large gold mining area, and has been stopping in front of this excavation area. As soon as he got out of the car, Wang Xudong saw that there were several excavators working there, and there were many people on the periphery, stretching their necks one by one, and some people even exclaimed in surprise!

…………

The first one is sent!
