As for mining, everyone knows that it is the most expensive part of the whole process, and if you don't pay attention, the cost of mining alone can make you unprofitable.

Beneficiation is the process of separating useful minerals from gangue minerals by using gravity separation, flotation method, magnetic separation method, electric separation method, etc., according to the physical and chemical properties of different minerals in the ore, and separating various symbiotic (associated) useful minerals from each other as much as possible, removing or reducing harmful impurities, so as to obtain raw materials required for smelting or other industries. Beneficiation can enrich the useful components in the minerals, reduce the consumption of fuel and transportation in the process of smelting or other processing, and make the low-grade ore can be economically utilized.

To put it bluntly, beneficiation is a process of rough refining.

However, for Lin Yi, it is not difficult to find the ore vein, but the difference is the quality of the ore vein.

Because mining extracts the metal ore from the ore, if the amount of metal ore in the ore is too small, then you may not make money and lose money.

This is also known as rich and poor mines.

But Lin Yi can only find mines, and there is really no way to get rich or poor in the veins.

So this kind of thing also depends on character.

"As an Asian, I've surpassed the Emperor, so. My luck was absolutely good. Lin Yi cheered himself up.

Looking back at recent events, you can see that his luck is really good.

Entering the desert in August, the temperature is frighteningly high, and the desert at this time is simply the hottest time.

The temperature was about forty or fifty degrees.

Lin Yi wandered around this desert and mountain of more than ten square kilometers for a week.

He was relieved to find out the gold mine.

Standing on the top of the superstition mountain, looking at the peaks and valleys at his feet, Lin Yi smiled, in his field of vision, this mountain peak and the ground were all golden.

That's the most glamorous color in the world, the color of gold.

From ancient times to the present day. The color that has been seducing countless people.

And in the valley, in a small mountain crevice, there is a sealed cave, which leads to the middle of the mountain, to the place where the veins are located.

Wandering into the cave and looking at the golden rock in front of him, Lin Yi took out the legendary mining artifact, Tai'a Sword.

Because of its sharpness and repairable reasons, this poor Tai'a Divine Sword has now become Lin Yi's most useful tool, and it is simply messing around.

If he is seen by researchers, he will definitely be criticized to death.

The sword weapon in his hand danced quickly, sliding quickly on the wall, and two golden ores fell on the mountain wall, reaching out to collect the two ores into the space, and after taking out a few ores from several other places, he quickly fled from the ground to the city.

To be honest, the past few days in the desert have made Lin Yi suffer enough.

The extreme heat, the terrible temperature difference, and the threat of snakes and insects make every day an ordeal.

If he hadn't had space on his body, he would have slept in the space at night, and he would have entered the space during the day when he couldn't stand it, and he wouldn't have been able to stand it a long time ago.

Lin Yi, who was on the run, glanced back at his back, it is still difficult to open a mine here, because there is no water source here!

After returning to the city, he flew directly back to New York, and by the way, he sent the two mines to a research institute for testing.

"Sir. You're back. ”

Hearing that Lin Yi was back, Dawson quickly appeared in front of Lin Yi.

"How's the negotiation?" poured a glass of monkey wine for Dawson, Lin Yi asked.

"Again, there's not a lot of progress, the guys are deliberately delaying, and they're getting the word out that we want to take a stake in Tiffany, and now that Tiffany's stock market is doing well, it's a bit of a problem. Dawson said.

"How so?"

"There are people on Tiffany's board who don't agree with us coming in. Thinking that we are wolves and will devour them, we have been in a stalemate, but through the stalemate, the other party has found the benefit, so now we are in peace with the mud!" Dawson was also a little helpless.

"But these days, we have received the shares of Baifeng Yisan again, plus the previous one, we already have 15 percent of the shares in our hands, and 25 percent of the joint Daimler, if we go to the board of directors, we also have a lot of say. ”

Lin Yi shook his head.

"If you want to do it, you have to hit it right away, and if you expose it too early, the next action will not be easy to complete. ”

"Hmm!"

"Stop the negotiations and send the message, the news of cooperation is fake news. Since they want to play, then let's have a good time, now we should have a lot of money in our hands, what should we do, I don't need to teach you. ”

"Of course! I'm a professional. Dawson understood what Lin Yi meant.

"By the way, go find a detection team, and then you need to explore a mineral, and also, find a way to buy the superstition mountain. Lin Yi said.

"Minerals, Superstitious Mountain?" Dawson was stunned for a moment, searching in his mind for a moment, and then remembered what this place was.

Because Lin Yi often hunts for treasures, as an assistant, he naturally has to learn about treasures. And Superstition Mountain is one of them.

"The Dutchman's gold mine has been found?"

Lin Yi nodded, "The sample has been sent for testing, and I believe that the results will come out soon, but according to my judgment." The color of this product is very good. The gold content is high, and importantly, the interior of the mountain is a gold mine, which can be said to be almost an open-pit gold mine. ”

Dawson's heart twitched, open-pit gold mine?

What a stroke of luck......

What matters when mining is the cost is the cost.

Open-pit mines are very cost-effective.

A mine is dozens of meters underground, and a layer of soil can be seen as long as a layer of soil is removed, and the size of this cost is not even calculated.

In addition to the open pit, there is another important aspect of cost, and that is the grade of the vein.

In the mineral resources industry, there is a well-known law that "the higher the grade vein, the lower the cost of extraction!"

This is a consensus reached by those who have been mining mineral resources for hundreds of years.

After all, on this earth, many mineral resources exist in the form of chemical compounds, which are called ores. Therefore, modern mines dig ore directly, ores containing various mineral elements.

Take silver ore as an example, generally speaking, the mining boundary grade of silver ore is 40 grams ~ 50 grams / ton, and the normal industrial mining grade is 80 grams ~ 120 grams / ton, just calculate it according to the grade of 100 grams / ton, if you want to get a ton of pure silver, you must mine at least 10,000 tons of silver ore to extract a ton of pure silver from these ores.

And if you have a vein grade of 200 g/t, then you only need to mine 5,000 tonnes of silver ore to get one tonne of sterling silver. The gap between the two is the gap between the cost of extraction.

The higher the grade, the lower your mining costs!
