There is naturally a reason why Han Kongque moved his camp here, and the biggest reason is that there is a huge cave under the east peak of the canyon, and the easiest place to enter the cave is
In this canyon.
After wandering around for half a month, the only larger cave Han Peacock found was here, but this cave was completely buried underground and had no population.
After three days of running around, Han Peacock found this canyon. The cliff here is closest to the cave. It is easiest to open a passage and enter the cave by digging from this side.
The reason why it is so troublesome is that Han Peacock wants to go deep underground through this cave to see if the emerald deposit here has any mining value.
"Are you sure this emerald vein passes through here?" Chen Jiayi looked up at the towering mountain peaks.
Just now they were looking for emeralds in the mountains, and now they are here digging holes to get into the ground. Isn't this gap too big?
"There is a fault here. The rocks above are the same as the rocks below. If there are emeralds on the top, there is no reason why there is no emerald on the bottom." Han Kongque said.
Although it is a bit irresponsible to say this, Han Peacock can't help it. Recently, he was almost vomiting from observing the emerald ore.
This huge deposit is not filled with emeralds everywhere, so in order to determine the scope and main distribution location of the emerald deposit, Han Peacock had to track the underground beryl in real time. Fortunately, beryl is very special, otherwise
The Korean peacock really couldn't track it for a long time.
Generally speaking, the journey of exquisite emeralds from mines to markets initially begins with geological exploration and the extraction and analysis of ore samples.
The most indispensable thing here is all kinds of ores, and Han Kongque has seen these ores countless times. So he finally chose a small mine here.
Generally, small independent mines will manually clean the gravel to analyze and determine the mineral content of the emerald in the sand and gravel, so as to guide people to determine the specific location of the emerald veins.
There are few emerald mining areas in the world that can always mine high-quality emeralds using open-pit mining like the Belmont mining area in Brazil.
Of course it won't be simple here. Han Kongque is fully prepared, but now he can only use a percussion drill to drill holes in the rock wall. After drilling a deep hole, he can then blast it.
The speed of digging holes is not slow in this way. What is slow is analyzing the excavated rocks and mineral sand to adjust the direction of the mine at any time.
"Is this the cave you're talking about?" Chen Jiayi felt like crying as he looked at a crack that went deep into the ground in front of him.
After working hard, not afraid of getting dirty, and not afraid of the danger of landslides, I finally managed to get through a passage of more than ten meters, and found that the front was just a gap deep into the ground, and this was the underground cave that Han Kongque said.
"It will be more and more spacious down there." Han Kongque would definitely not tell him that only if you go deeper than a hundred meters underground, there will be some small holes that are as high as a person and half as wide as a person. If he told him, he really didn't know if Chen Jiayi would.
Will turn around and leave.
Anyway, this time I came here just for a trial excavation. This is the Sierra Nevada Mountains after all, and prospecting and mining are not that easy, so even if an emerald mine is discovered, future mining will be troublesome.
"Be careful. The ore collected from different locations must be collected carefully." Han Peacock ordered while watching Jin Yao and the others working.
Now no one knows whether there are gems among these stones, and there are too many ores. Han Peacock did not have the time to search carefully bit by bit.
This place is located on an emerald deposit. Although he did not search carefully, Han Kongque believed that there were emeralds here.
So the ore was cleaned out and transported to a small river for further processing.
The first is to study these ores. Emerald deposits are a type of beryl gem deposits, so emeralds are beryls containing chromium. The formation of emeralds is strictly controlled by the source of chromium and the source of beryllium. Both are indispensable.
Emerald is a kind of emerald green transparent beryl with large grains that can be made into high-grade gemstones, so emerald deposits are very rare.
Since it is green, it can also be seen with the naked eye, and Han Peacock is already familiar with the mica flakes among these ores. Others, such as quartz, calcite, and talc veins, are also easy to distinguish.
This is a hydrothermal emerald deposit. Produced in ultramafic rocks, the ore bodies are emerald-containing vein-like mica rocks and emerald-containing quartz-calcite-talc veins;
With these discoveries, we can actually be sure that emeralds must be produced here, but we don't know how many emeralds there are and what their quality is.
Cleaning the gems with water to reveal their original appearance is a necessary step. Large mine owners often use high-pressure water guns to clean the sand and separate out the rough emerald stones.
Han Kongque and the others were unable to use complicated pipeline separation methods to separate the ore from the sediment. They could only use the most primitive method, like gold mining, to wash away the sediment to discover gemstones.
When washed in water, the lightest sediment is washed away first, while the heavier ores, including emeralds, continue to remain on the sieve and enter the final separation process.
In fact, when looking for gems, if the output of gems is large, you can use an optical sorter to sort them, so that not a single gem will be lost. However, except for Belmont, other colored gemstone mining areas in the world rarely use optical sorters.
, identify and preserve ores containing emeralds.
After all, the ultimate goal of mining gems is to discover rough emeralds that have processing value, improve efficiency, and finally reach the market and meet buyers.
The most important issue here is the cost. Only when the cost is low can you make money. If the mining is too difficult, too few emeralds are found, or the quality is too poor, then you will not make any money, or you will simply lose money.
Therefore, although many emerald deposits have been discovered around the world, the vast majority of emerald mining areas still use low-level methods to mine emeralds in hard rocks by drilling holes and using explosives.
After drilling holes in the rock, put explosives in, and then prepare to detonate to mine the ore. If explosives are not used, mining will take longer and require more labor.
Large underground mines often use heavy-duty bulldozers to load ore into rail trolleys.
Mechanization has greatly increased transportation efficiency. Therefore, the potential output of emeralds has also increased. As the output of emeralds increases, the price will naturally decrease. When the price decreases, costs must be controlled again, and the best way to reduce costs is to lower costs.
, that is, increasing production, which enters a vicious cycle.
Han Kongque and the others had few people here, so they could only rely on tools. Through the chaotic space, Han Kongque got some domestic mine carts. As long as they jumped on two simple tracks, these mine carts that were originally used to transport coal could be used.
Transport the ore in the cave to the river.
In the future, these mine cars will also be the main tools here. When the rail cars are full, they will move along the tracks to where they can be directly loaded and transported out of the mining area.
If the emerald mine is deep underground, a winch can be used to drag the rail mine car, while in some simple mining areas, human power is used to pull it.
This is actually the same as mining coal in a coal mine. They are both mining. Han Peacock has never seen it in the gem mining area, but Han Peacock knows that in some coal mines, miners directly dump the ore from the rail mine car into the transport truck above.
In the well.
Once the transport truck is in place, the door of the transport shaft is opened, and the ore poured from above flows into the truck through the funnel-shaped pipe.
The truck travels along the ramped mining area road, and the transport truck loads the ore and leaves the mining area to enter the next processing process. The mined ore passes through the cleaning system and screening system on the conveyor belt to separate the required mineral deposits.
In gem mines, this can definitely be done, but most mining areas use artificial methods to separate gems.
In old mining areas, workers can skillfully and carefully sort to avoid missing any stone containing emerald.
Finally, emerald rough stones are generally wrapped in the main rock and still need to be re-distinguished and summarized.
This requires the Golden Demon to come over and crush these ores to see if there are any emeralds in the rough ores. If there are any, it is necessary to confirm the quality of these emeralds.
This process is very tedious, and the most important thing is to be careful. It is similar to selecting diamonds. It requires concentration, slow work, and meticulous work.
"If the mine is really opened, a large number of people will definitely be hired to carry out this kind of work." The golden demon muttered while working.
"There are so many people in the world who don't have enough to eat. It would be great to have a job like this. If we really need to hire a large number of people, this will be a blessing." Chen Jiayi said leisurely.
Chen Jiayi stopped working a long time ago. He came here to broaden his horizons and travel, not to work as a coolie. It felt very fresh at first, so he helped to dig holes, but now, he only helps to identify emeralds.
In other words, after seeing too much, he really has some discernment now.
Han Kongque was picking out emeralds. When he heard Chen Jiayi's sarcastic remarks, he immediately said: "Only some small mining areas will employ a large number of people. However, it may be possible to do this in the United States, hiring a large number of local workers and providing as many people as possible."
With more jobs, it may be easier to convince the local government to give us exploration and mining rights.”
"You are a profiteer." Chen Jiayi said.
Han Kongque smiled and ignored him. He was the one who said everything, but Han Kongque was really serious about it.
Some small independent mines often use relatively primitive and time-consuming methods to separate emeralds and rocks. They almost use manual hand washing, separation and selection to find emerald ores. (To be continued.)
