At this time, in June, it can be said that the best time to go up the mountain, the apples are also in bloom, and the whole hillside is full of small red and white apple blossoms.

Another special point is that the rock shape here is strange, and it can even be said that the strange rocks are craggy, there are many vertical cliffs on the mountain wall, and the exposed granite has a flowery green color, as well as layers of wavy structures, which makes the scenery extremely beautiful.

Director Zhou praised the good mountains again and again, and walked to a mountain col that overlooked the whole city of Almaty.

Director Zhou cupped his forehead and observed, and asked, "What is the altitude here?"

"About 2000 meters. ”

"It's a pity, what a good industrial base, it's not developed. ”

Fan Yangleng, he can talk about animals and plants, but he doesn't know anything about geology: "Huh?"

This section of the winding mountain road, to the periphery of the mountain, the line of sight is very open, the left is the mountain, the right is the cliff, you can see the whole picture of Almaty.

Director Zhou propped up the handrail and pointed at the mountain wall on his left: "We are engaged in geology, in fact, to put it bluntly, it is a science of looking at mountains, and basic industry is built on mines, you must know how to distinguish." ”

On the left-hand side is a white rock, which in Fan Yang's eyes is the most sparse stone.

But in Director Zhou's eyes, it was different, and he said, "Do you know what kind of stone this is?"

Fan Yang shook his head and said he didn't know.

Director Zhou said: "Isn't this limestone, but also the most common sedimentary rock, let me tell you, more than 60% of the mountain, are made of this kind of rock, is the most basic part of the rock, but also the cheapest, but in our eyes, as long as it is a mountain, it can be used, like this white rock, the main components in it are carbonate and calcium carbonate, mined can be fired lime, fired cement, iron and steel, can be said to be an industrial binder, this is not the industrial base of what?"

"Huh. Fan Yang was intuitively amused.

Director Zhou smiled and pointed to a mountain wall opposite, the rocks on it were not one by one, but layer by layer, lime-like rocks.

Director Zhou said: "Look at that, that is shale, is the soil deposited, this rock is strong in argillace, can be broken and used to burn bricks and tiles, in short, each has its own use, the so-called industry, is a geological wealth into industrial products of science, even the soil can be fired ceramics, river sand, can also be turned into glass through high temperature, iron and steel, digging coal, burning cement, this is not the industrial base?"

"See, you're talking about an industrial base built on minerals, and minerals come from the mountains?"

Seeing that Fan Yang can understand a little, Director Zhou is still very happy: "Agriculture depends on soil, industry depends on rock, but not any mountain range has development value, because limestone is too basic, if there is no mine in the mountain, you just knock lime, then you can knock anywhere." ”

"Where is the mine?"

Director Zhou pointed to the mountain wall: "Hide inside." ”

Fan Yang suddenly realized again: "You mean to say that these ores are hidden in the belly of the mountain?"

Director Zhou said: "This needs to be explored, no matter how you dig in the general mountain, there is no ore after mining, it is all limestone, like this kind of mountain, it is basically no fun." ”

"What about the ore ones, how can you tell the difference?"

"Look for granite, look at the color, red and black, gold and yellow, as long as the color is different, there must be mine. ”

Fan Yang immediately understood: "When we walked over just now, we saw a layer of red rock wall, the color on which was like pork belly, does that mean there is a mine?"

"Yes. Director Zhou said with a smile: "Let's find a way to find a mountain and find minerals, the first thing is to look at the color, but you can't see it in general, the outside of the mountain is covered by rock formations, like the place just now is a hematite." ”

Fan Yang only felt dizzy: "Just walked up to the circle, and you found an iron mine?"

Director Zhou said with a smile: "Where can I find it, so obviously you can't see it? You can see it at a glance, of course others have seen it, and the open-pit deposit is proven." ”

"Iron ore so easily?"

"It's a big deal, iron ore is everywhere, you can pick up two stones and knock out iron powder, what's the big deal, otherwise our five small industries and thousands of iron and steel factories are distributed in various counties and townships, what do you rely on to produce steel? It's just that the quality is too poor, and if it's too poor, there is no development value, like the igneous mine just now, the estimated content is less than 40%, and there is no mining value. ”

Fan Yang still stayed on topic: "What about the gold mine?"

Director Zhou laughed: "Young people are too stubborn, is it so easy to find gold mines? Gold mines are difficult, gold is different from iron, iron is the largest reserve of elemental metal in nature, the content is still high, the iron content is more than 60%, it is called rich ore, below 60 is called poor ore, below 40 there is no mining value, but gold is different, widely distributed, low reserves, gold content can reach 1% is considered a rich mineral, a ton of ore can be mined out of two or three grams of gold is very good. ”

"It's only two or three grams a ton?" Fan Yang only felt very disappointed: "It's only two or three grams? No, how can it be mined? I heard people say that when you pan for gold in the water, you can make ten grams and eight grams a day, what's going on?"

Director Zhou said with a smile: "Shajin is different, the characteristics of gold are small reserves, wide distribution, from the river to dig out of the luck to see the luck, the deposition time is enough, like the herdsmen in Inner Mongolia looking for minerals, digging a pit at will, you can also find a lot of sands, but you can also find out gold eggs, dog head gold, but these are small-scale private mining, applied to industry, generally mining rock gold ore, copper and gold associated, or iron and gold associated, the gold content is naturally less." ”

Hearing the golden egg and the dog's head gold, Fan Yang didn't feel excited, after all, he had dug it himself.

After having that golden lake, there are only tens of hundreds and eight grams, and they don't pay much attention to it.

But the concept of rock gold mine is different.

He seriously suspected that Zakin Mountain was a cave where he entered the mountain and found the dzi, but there was a wind blowing out of it, and the air could circulate, and if he listened carefully, he could still hear the sound of water, and he judged that there was a cave inside, and if it was not done well, there would be a real gold mine.

It's just that the ability at that time couldn't be mined.

At this time, when I heard that the rock gold ore content was very low, I suddenly felt lost in my heart.

"It's so low, is there anything special, the gold content is particularly high, is there any?"

Unexpectedly, Director Zhou nodded: "Of course there is, unless you find a pure gold mine." ”

"Pure gold?" Fan Yang's heart began to pound: "Then what is a pure gold mine?"

"General industrial mining is complementary to steel and non-ferrous metals, such as gold mines next to copper mines, which are refined separately, so the gold content is more than 1% It is valuable, the value is not high, and it is pure gold ore, there are many kinds of his ore, such as granite-type ore, with a gold content of one gram, quartz vein-type ore, gram, altered rock is powerful, the probability of finding it is very small, the gold content is more than 200 grams, and the most powerful one is the Carlin-type gold mine found in San Francisco, USA, which can reach up to five or six hundred grams, or even more than 1,000 grams, setting off a gold rush in the United States for decades. ”

After speaking, Director Zhou turned his head: "Why do you keep asking about the gold mine? Did you find one?"
