"What is fluorite, is it a gemstone, is it expensive?" asked Jin Yanzi curiously at the meeting.

Other shareholders also cast inquiring glances at Zhang Shanfeng.

I saw that his eyes were glazed, and he looked fixedly at the fluorite specimen retrieved from his mine in front of him.

In order to resolve the embarrassment, Liang Qing quickly stood up and came to the projection screen.

Holding a laser pointer in her hand, she began to tell everyone about the PPT fluorite-related introduction documents she prepared during the day!

"Fluorite, also known as fluorite, is an equiaxed crystal system with calcium fluoride as the main component. Crystallization into octahedron and cube. Its brightly colored, crystalline specimens can be used for collection, decoration and carving crafts. ”

"Like what the president is holding in his hand now, it is the fluorite sample that was collected from our Jincheng mine. Liang Qing pointed to the fluorite specimen in front of Zhang Shanfeng with a laser pointer and continued.

"Wow, it's so beautiful, this piece of blue and blue is as transparent as seawater!"

"Yes, the color of fluorite is very rich, the specimen in the president's hand is mainly blue-green, in addition, according to the trace elements contained in fluorite itself, fluorite also has purple, pink, cyan, yellow and other colors!"

Liang Qing used a laser pointer to turn out a new page of PPT, and specimens and ornaments of fluorite of various colors appeared on the big screen. Then she continued.

"In the Neolithic Age, the Hemudu people in China used fluorite for decoration. The mining and excavation of fluorite originated in ancient Egypt, when people widely used fluorite to make statues and carvings in the shape of scarabs. In ancient Rome, fluorite was widely used as a precious stone in the production of wine glasses and vases, and the ancient Romans even believed that fluorite wine glasses would make people not drunk. ”

Liang Qing turned another page, and a large number of fluorite wine cups and vases taken out by foreign archaeologists from the ancient tombs appeared, although some of them were dilapidated, but they could still feel the mysterious beauty.

"Is it expensive to make ornaments from this gemstone, and why haven't I heard of it before?" asked a middle-aged man in his mid-fifties.

"Fluorite is known as "the most vivid gemstone in the world" due to its vivid and rich colors and smooth crystals. However, it has a low hardness, so it cannot normally be used as jewelry. As we all know, in the ranking of various expensive gemstones, the harder it is, the more expensive it is, such as jadeite, diamonds, etc. ”

"But because of the soft texture of fluorite, it is relatively easy to use it to carve ornaments when there are large enough crystals. There are some specimens in good condition that can also fetch a high price. ”

"That is, you can only sell for a good price if you find good condition?" asked a woman in her mid-forties.

Everyone heard that the value of fluorite as a gemstone was not as high as expected, and several shareholders in the jewelry investment field began to whisper.

"In the field of gemstones, fluorite has its limits to its investment. However, in terms of industry, fluorite is the only one that can refine a large number of fluorine minerals and can extract and prepare fluorine elements and various compounds, so in the industrial field, fluorite is a necessary raw material for medicine, optics, and metallurgy!" Liang Qing deliberately accentuated the word "only".

As soon as everyone heard the word "unique", they immediately became interested, and the value of this thing is irreplaceable!

"Now the domestic market, because of strict control, I heard that the import of fluorite has been completely interrupted, that is to say, the Z country of Nuoda can only use fluorite mined in its own country!" said a middle-aged man with a capable appearance.

When everyone heard this, they were in an uproar and gave Zhang Shanfeng a thumbs up.

"Mr. Zhang is amazing, he has such a vision at a young age, and the value of these mines is really immeasurable!"

For people's praise, Zhang Shanfeng, who had returned to his senses, barely squeezed out a smile, he looked at Liang Qing and motioned for her to continue.

"When fluorite is irradiated, the electrons in its mineral will enter the high-energy state from the low-energy state under the stimulation of external energy, and when the external energy stimulation stops, the electrons will turn from the high-energy state to the low-energy state, and will emit light in the process. Fluorite can shine for dozens of hours after being irradiated by fluorescent lamps, this kind of light is relatively weak, it cannot be seen during the day, and it is very bright at night! In addition, the priceless night pearl that everyone is more familiar with and that Empress Dowager Cixi held in her mouth when she was buried is fluorite!

"Oh my God, no wonder!"

"Night Pearl, where have ordinary people seen it. ”

"It's all written in a book, I thought it was just a legendary thing, but it turned out to be fluorite!"

This time, everyone's discussion was louder.

Liang Qing smiled and motioned for everyone to be quiet. She continued.

At the same time, fluorite is also used in steelmaking as a green cubic octahedral fluorite single crystal co-solvent to remove impurities. The mineral is also used in the production of glass and enamel. In addition, there is a large demand for fluorite in the field of optics. Its synthetic crystals can be made into a variety of lenses when they grow up. For example, a camera lens made of fluorite has a very low dispersion, so the lens made from it has less chromatic aberration than a lens made of ordinary glass. ”

"Moreover, only very high-configuration and very high-priced cameras can use lenses made of fluorite, because a natural and transparent lens, it is close to the light perception that we humans see with the naked eye, and can restore the colors of nature most realistically. The single-lens reflex camera Canon EOS Moonlight Goddess series that we are more familiar with is made of fluorite!"

"No wonder my relatives always say that playing SLR, poor three generations, the lens will never be enough, hahaha, in this way, the price is worth it!" said a young man.

"In addition, fluorite ore is a secondary mineral in granite, pegmatite, and syenite. Minerals symbiotic with fluorite are: scheelite, apatite, topaz, cassiterite, wolframite, pyrite, calcite, sphalerite, lazurite, muscovite, quartz, galena, dolomite, chalcopyrite, albite, spinel, rhodochrosite, barite. ”

"Therefore, in the process of fluorite mining, as long as we can rationally use the production capacity, the value of the symbiotic minerals in these mines is immeasurable!

After all the talks, Liang Qing looked at everyone and smiled confidently!

After listening to Liang Qing's introduction, Jin Yanzi and other major shareholders present couldn't help but get excited, although it was late at night in winter, everyone felt that they saw the infinite dawn of golden light.

"Zhongying wants you to come out, not money, but the mining plan, is a good price to buy our fluorite minerals!

Zhang Shanfeng said a concluding statement lightly in the excited crowd.
