The first thousand six hundred and forty-nine chapters dog head gold
Zhou Meiren said: "I still have some confidence in this. Gold ore and chalcopyrite are different."
"If you are really confident, then take a look at this piece of ore." As he said that, Han Kongque took out a piece of yellow ore and handed it to Zhou Meiren.
"Really testing me? This piece is definitely not gold ore, but I still have some confidence." Zhou Meiren gave Han Kongque a charming look.
Han Kongque smiled and said nothing, while Zhou Meiren took the ore and looked at it carefully.
"Huh? Is it really pyrite?" Zhou Meiren clearly saw that Han Peacock picked it out from a pile of gold ore, so why was it also mixed with chalcopyrite?
Han Kongque said with a smile: "It's nothing strange. There is an iron ore vein not far away."
"It's really fool's gold. I've heard of it before, but this is the first time I've seen it." Zhou Meiren said with a smile.
It is very easy to mistake chalcopyrite, pyrite and natural gold ore, especially pyrite, which is also known as "fool's gold".
The method to identify them is actually very simple. Chalcopyrite is distinguished from pyrite by its more yellow color and lower hardness. It is distinguished from natural metal phase by its green-black streaks, brittleness and soluble in 3.
Use the ore to scratch the unglazed white porcelain plate. The streaks made by the natural gold ore, that is, the powder left on the white porcelain plate, will be golden yellow, while the streaks of pyrite will be green and black.
In addition, you can also weigh it with your hands. The natural gold ore that feels particularly heavy is because its density is much greater than that of pyrite and chalcopyrite.
"These ore specimens are very good. As long as they are collected, they can be used for publicity." Zhou Meiren immediately thought of the use of these ores.
Han Peacock nodded and said: "Last time, I found a lot of ore specimens in the waters of Hawaii. After I returned to the United States, I built a mineral museum there. I didn't expect to find so many natural gold ores here. It seems that domestic ores
The museum is also about to open.”
"There is a lot of natural gold here. If you choose carefully, it would be good to build a gold mine specimen museum, or directly build a gold jewelry flagship store to specifically display these nuggets. You must know that Chinese people like nuggets very much." Zhou
The beauty obviously thinks more long-term than the Korean peacock.
When Han Kongque heard this suggestion, he immediately laughed. Compared with Zhou Meiren, Han Kongque didn't look like a businessman.
Han Peacock picked up a piece of ore casually. The golden ore was pitted with pits, and it looked like his face was covered with pockmarks.
"This is spongy natural gold, a very common type of natural gold." Zhou Meiren said.
Han Peacock nodded. This rough stone has a large amount of sponge-like natural gold, arranged together with a small part of quartz. If these quartz and limonite were not attached to one side, this would be pure natural gold.
Among them are some larger, shiny natural gold. These slightly rough crystallized nuggets are distributed on the entire ore. They don’t look very beautiful, but they are definitely golden.
"It's not as beautiful as this one." Han Peacock picked up another piece of ore and said.
"This is a piece of natural gold composed of beautiful matrix-free gold crystals. During its formation, the gold crystals are bent and twisted, like a sculpture, which is naturally very beautiful." Zhou Meiren said.
Watching Han Peacock picking at the side, Zhou Meiren continued: "The sponge-like gold ore just now can be displayed as a typical specimen of natural gold, and the natural gold made of gold crystals just now are all
Natural gold like this that can be exhibited is not easy to find in the wild."
"Finding some natural gold with typical characteristics will definitely shock people's attention." Han Kongque said with a smile.
This world is a world based on looks. Everyone likes beautiful things, so gold ore is no exception.
"Look at this, isn't it beautiful?" Han Peacock picked up a piece of gold ore again and said.
This is a piece of natural gold formed in a flake shape. The surface is covered with microcrystalline holes. It is very beautiful when magnified.
Zhou Meiren shook her head and said: "This is not the most beautiful. The most beautiful gold ore should be natural gold with rounded edges worn by alluvial layers. Look at this piece, the edges are very smooth and have a metallic texture.
,isn’t it beautiful?”
There are two pieces of natural gold that Zhou Meiren holds in her hand. They are natural gold with metallic luster. The edges have been slightly rounded due to alluvial action. One piece is like a goose egg and the other is like a water drop. They are both very beautiful.
Next, Zhou Meiren selected a lot of natural gold, including natural gold that looks like a rockery, natural gold that is associated with quartz, and natural gold that is carved from calcite.
There is also a piece of natural gold that is forty centimeters long, slender and fan-shaped, with feather-shaped natural gold crystals and residual quartz attached near the bottom.
The few pieces that Han Kongque found were also pretty good, including a very plump piece of natural gold arranged in the shape of leaves, and a piece of natural gold nugget shaped like a horn that had been impacted by water.
These beautiful natural gold crystals form an intertwined chain-like aggregate. The original large crystals of natural gold have a beautiful sharp luster. When you observe this feature under a magnifying glass, it looks particularly amazing.
Pieces of natural gold were discovered and collected by Han Kongque and Zhou Meiren. Among these natural golds, there were all kinds.
Natural gold with a massive crystal structure in parallel directions, very shiny natural gold with a small amount of milky white quartz locally, water-worn or snail-shaped original natural gold ore.
And there are more gold ores with shiny small spots of natural gold on the gray bedrock.
Of course, there are also some strange shapes of natural gold, such as flat gold crystals with metallic luster, which form tree-like natural gold crystals with purple quartz at the central spine. If size is not considered, this is the legendary golden tree.
Others include some funnel-shaped and coral-shaped natural gold.
Natural gold can be in the form of dendrites, granules, flakes, lumps, etc. However, the natural gold discovered by Han Kongque and Zhou Meiren here is not very big.
Of course, if the several-ton boulder we saw earlier counts, then that piece of gold ore is a giant.
However, that piece of natural gold ore is only dotted with granular natural gold as large and small as stars, so although it is large, it cannot be regarded as qualified natural gold.
The heaviest piece of natural gold found by Han Kongque containing a large amount of gold did not exceed one hundred kilograms. In other places, more than 200 kilograms of natural gold have been discovered.
The gold ores discovered now should all belong to mountain gold. Of course, there is no shortage of vein gold and alluvial gold here.
Natural gold produced in primary mineral deposits is commonly known as mountain gold, natural gold produced in mineral deposits mixed with other minerals or rocks is called vein gold, and gold produced in placer mines is called alluvial gold.
Compared with nugget gold, Han Peacock actually does not value alluvial gold. Alluvial gold is ordinary gold. Its most useful function is to make gold bars for storage or make gold jewelry for sale.
For the current Han Peacock, exchanging gold for some useless pieces of paper is putting the cart before the horse. Instead of exchanging some useless money, or simply turning it into numbers and storing it in the bank, then Han Peacock might as well exchange gold for some
Supplies, or simply keeping some gold reserves can be useful.
Now Han Peacock is reversing the course of history. He is turning the original credit currency into physical currency again, that is, gold standard currency.
The coins currently used in the entire Peacock Island waters are gold coins discovered from gold reserves. Although gold coins are also paper currency, these paper currencies can be directly exchanged for gold from the banks on Peacock Island.
In this way, this is real currency, not waste paper issued arbitrarily by other countries.
Of course, saying waste paper seems a bit excessive, but as long as you know that the currency issued by some countries can only be used in your own country, after going abroad, it becomes real waste paper, and you will know that what Han Peacock said is not unreasonable.
.
If it weren't for this, China wouldn't have spent so much money to turn the RMB into an international currency that could be directly used as a settlement currency for international transactions.
What does this mean? This means that in the future, the paper printed by the Chinese can be used directly to purchase foreign materials, such as ores, luxury goods, food, etc.
It turns out that this is how Americans play, and now, our country is finished like this. Therefore, credit currency is equivalent to waste paper if others do not agree with it.
However, Han Peacock did not have the strength or reputation to be recognized by others, so he could only use gold standard currency to promote his Peacock Gold Coin policy.
Don't think that Han Peacock is doing a thankless job. He seems to be making simple things more complicated. In fact, they are all without benefit and cannot be done early.
Because everyone knows that the more banknotes are issued, the more profitable it is, because you can issue more banknotes. Of course, this is based on having a certain gold reserve. Otherwise, if you issue too much currency, if you face a run on the crowd, then you will directly credit
bankrupted.
The reason why Han Peacock dares to use the gold standard to issue currency is because he has a lot of gold in his hands, and a large part of it is the harvest of Han Peacock's treasure hunt, and part of it is supported by the technological strength of Peacock Island.
You must know that the Korean peacock controls a large area of the ocean, and what is the most abundant in the ocean?
It is a mineral, so there is gold in the sea water, but it is very troublesome to refine it.
There is also natural gold in seawater, about 10 micrograms per ton.
Natural gold is mainly produced in gold-bearing veins formed by high- and medium-temperature hydrothermal fluids, or in medium- and low-temperature hydrothermal deposits related to volcanic rock systems and volcanic hydrothermal processes.
Because its shape and appearance are very unusual, it has also aroused the interest of scientists. Researchers from the Devil's Island Institute of Biology under Han Kongque carried out experimental research on the microbial mineralization mechanism of "Noghead Gold".
They isolated bacteria from the water and soil samples of gold mines and found that these microorganisms are good at adsorbing and aggregating soluble gold in the body to form a colloid in the early and middle stages of growth.
Colloidal gold complex ions are reduced and precipitated into natural gold. To be continued.
