Natural gold, also commonly known as "dog's head gold". Pen "Fun" Pavilion www.biquge.info

Natural gold is a naturally occurring elemental gold mineral, a natural nugget from vein or placer ores. Because the shape resembles the shape of a dog's head, it is also known as dog's head gold. Metals such as silver or trace amounts of copper are often present. Generally, it is a loose or irregular dendritic aggregate, and individual blocks can weigh tens of kilograms. The color and streaks are golden yellow. Metallic luster.

The piece that Lin Hu is holding in his hand is golden yellow, very similar to the rumored natural gold, but Wang Xudong is still far away from Lin Hu, and Wang Xudong's eyesight is not very clear, so he has to walk in and look carefully to know.

Seeing Lin Hu shouting excitedly, Song Qingsong's interest also came up, and he said loudly: "Boss, is it really natural gold, if it is, then you will be rich." ”

Wang Xudong and Song Qingsong trotted all the way to Lin Hu's side, Song Qing's eyes were sharp, and he saw that there were many on the edge of the waterhole, of different sizes, sporadically under the water, which was very conspicuous.

Oh my God, so many!

Is it really natural gold!

Song Qingsong didn't care whether his shoes would get wet with water, and he didn't have time to take them off, so he immediately walked over, picked up a piece from the clear water, and looked at it carefully in his hand.

Wang Xudong walked in front of Lin Hu, and Lin Hu immediately handed the piece of "natural gold" in his hand to Wang Xudong, and said happily: "Boss, take a look." ”

Wang Xudong took it and looked interested, but after Wang Xudong looked at it, he checked it in his hand again, and his brows furrowed slightly.

Lin Hu also noticed the change in Wang Xudong's facial expression, and hurriedly said, "Boss, is there a problem?

Wang Xudong smiled and said lightly: "This is not natural gold, it should be fool's gold, which is what we often call pyrite." ”

After speaking, Wang Xudong set his eyes on Song Qingsong, and his eyes seemed to say, Qingsong, you can talk about it.

Song Qingsong is a master's degree in mining engineering, and he is naturally much more expert in various minerals than Lin Hu, Song Qingsong checked the fool's gold in his hand, and then said: "Brother Lin Hu, this is indeed not natural gold, but as the boss said, this is fool's gold, that is, pyrite." ”

"Pyrite looks very similar to natural gold in appearance, many people think that this is natural gold, so pyrite is also called fool's gold, in fact, fool's gold and natural gold are very different, as long as you take it on the unglazed white porcelain plate, look at the scratch marks (that is, the powder left on the white porcelain plate), it will be true and false. The streaks of gold ore are golden-yellow and the streaks of pyrite are greenish-black. In addition, when you put it by hand, it is gold that feels particularly heavy, because the specific gravity of natural gold is 15.6-18.3, while pyrite is only 4.9-5.2. Also, if you soak it in nitric acid, real gold will not bubble. ”

After listening to Song Qingsong, Lin Hu took it in his hand and checked it, and sure enough, the weight was not as heavy as the feeling of natural gold, but the weight was a little light.

Just now, when Lin Hu saw these golden things at first glance, his first reaction was natural gold, and he was happy in his heart, where could he take care of so much, and immediately shouted and shouted.

Not natural gold, but just pyrite.

Lin Hu was a little discouraged, Wang Xudong just smiled slightly, encountering natural gold, this is an unavoidable thing, in nature, it is very rare, if you can really encounter so much natural gold at once, then luck is really a little against the sky.

Just now, so many delicious avocados have been harvested, Wang Xudong is already very content, not natural gold, just fool's gold, Wang Xudong also feels nothing.

Lin Hu looked pity and sighed slightly, "Boss, it makes me happy, I thought I was rich, I thought I had encountered so much natural gold at once." ”

Next to the waterhole, and at the bottom of the clear water, there are many pieces of fool's gold of different sizes, small finger sizes, big ones bigger than fists, if it is really natural gold, then it is really a fortune.

Generally speaking, natural gold of the same weight is much more expensive than pure gold, and natural gold is often several times more expensive than pure gold in terms of price.

Song Qingsong gently patted Lin Hu's shoulder and comforted: "Brother Lin Hu, natural gold is hard to find, don't think about it so much." ”

"Well, that's all there is to it. ”

It's not natural gold, but fool's gold, Lin Hu can only reluctantly accept the reality, and throws the fool's gold in his hand, which is bigger than a fist, into the water in a dejected manner.

Natural gold!

Thinking about gold, Wang Xudong remembered Australia's rich gold reserves, Wang Xudong thought in his heart, his newly bought land, an area of more than 1,500 square kilometers, I don't know how the gold reserves are, if this land has gold, then make a fortune.

Suddenly, Wang Xudong was full of interest, activated the "god-level big miner" system, and issued an order: "Miner No. 1, scan the reserves and distribution of gold in this area." ”

Miner No. 1's voice sounded in Wang Xudong's mind, and Miner No. 1 said, "Brother Dong, there's no problem, scan it immediately." ”

Soon, a huge three-dimensional hologram appeared in front of Wang Xudong, within a radius of ten kilometers and a depth of two thousand meters, the gold reserves and distribution in this huge range were clear.

Miner No. 1 said: "Brother Dong, the gold reserves in this area are very rich, but the location is a little deep, there are a total of one hundred and six tons of gold, if it is gathered into a gold mine, it will be a total of ten thousand six hundred tons of gold ore. ”

Oh my God, this is the real rich!

Wang Xudong didn't think about it, he inadvertently picked up such a big bargain, and bought this land for 15 million Australian dollars, originally wanted to open an iron mine, but he didn't think that the gold reserves here are so rich.

One hundred and six tons of gold, this can be regarded as an abundance of stock!

The "god-level big miners" are able to re-gather some low-grade, very scattered, or even non-mining value ores and regenerate them into very rich, very high-grade veins or open-pit ore seams.

The distribution of gold in this area is relatively scattered and buried deep from the three-dimensional map, and even if others have explored it, it is very difficult and expensive to mine, but Wang Xudong does not have such a problem.

Miner No. 1 asked, "Brother Dong, is there a gathering of gold mines? A total of 10,600 tons of gold ore will be generated." ”

The system regenerates and aggregates the ore that is scattered, low-grade, or even non-mineable, and in the case of precious or rare metals, the ore produced by aggregation is 1% pure.

If Wang Xudong wants to gather this batch of gold ore, after the aggregation is generated, the gold content of this batch of gold ore is one percent, that is, one ton of ore can refine ten kilograms of gold, and such a purity of gold ore is enough to make people red-eyed.

The gold content of gold ore is a little scary, Wang Xudong feels in his heart that he is not in a hurry to mine for the time being, but to open an iron mine first, and then open a gold mine after he has a certain strength, and mine all the gold.

Anyway, this piece will be his own, Wang Xudong is not in a hurry to gather gold mines, but is ready to take a look around, there are more than 100 tons of gold within a radius of 10 kilometers, and then the range is expanded, is there 200 tons, or 300 tons.

The more he thought about it, the happier Wang Xudong became, this time, he really made a lot of money.

Gold reserves are so abundant, but what about iron ore?

Wang Xudong's main purpose in buying this land is to open a large iron mine, so far, Wang Xudong has not scanned the iron ore, and I don't know how the iron ore reserves are.

Wang Xudong gave an order: "Miner No. 1, scan the iron ore reserves and distribution in this area." ”

Miner No. 1's voice sounded again in Wang Xudong's mind: "Yes, Brother Dong!"

Soon, the huge holographic three-dimensional map changed, and the iron ore reserves and distribution within a radius of ten kilometers and a depth of two kilometers were displayed.

Wang Xudong found that there was no Mount York on the holographic 3D map, and it was obvious that the location where he was located was more than ten kilometers away from Mount York, that is, Mount York was outside the scanning range.

On the holographic three-dimensional map, there are a lot of reds, which represent iron ore veins or ore layers, with different sizes and shades.

Miner No. 1 said: "Brother Dong, after the scanning, a total of 185 million tons of iron ore have been found, is there any accumulation of iron ore?"

It is worthy of Western Australia, where iron ore is grabbed from the ground at will, and the reserves of iron ore are really rich.

Especially in front of the "god-level big miner" system, those low-grade, no mining value of iron ore, the system is all scanned, as long as Wang Xudong gives the order of ore aggregation, these iron ores will all be transformed, remove impurities, and the grade can reach more than sixty-two.

Casually, nearly 200 million tons!

Of course, if there is a geological exploration of iron ore within a radius of 10 kilometers, no matter how careful and comprehensive the exploration is, it will not be possible to conclude that there are 185 million tons of iron ore reserves here.

Because in general, those scattered, low-grade, or deeply buried ores are not counted, while the "god-level big miner" system is all-round, no dead angle scanning, a radius of ten kilometers, a depth of two kilometers, nearly 200 million iron ore reserves, normal!

"Boss, what's the good thing, so happy?"

Seeing that Wang Xudong was in a good mood and almost laughed, Song Qingsong laughed suspiciously, Wang Xudong also came back to his senses and said with a smile: "I suddenly thought of a happy thing." ”

Of course, Wang Xudong would not say that he used the "god-level big miner" system to scan and found that there were abundant reserves of gold and a lot of iron ore.

Wang Xudong waved his hand and said, "Let's go, let's get in the car and go to York Hill to have a look." ”

Originally, the main purpose was to go to York Hill to have a look, but after a delay on the way, I have not yet reached York Hill. A group of three people, out of the canyon, Lin Hu carried this bag of avocados, threw them into the car, and then said, "Boss, I'll still drive." ”

Wang Xudong knew about Lin Hu's driving skills, Wang Xudong nodded and said, "Yes, you still drive, let's take a look at York Mountain." ”
