From Sun Yucheng's refusal to admit his account to the inauguration of "Jinyangshan Mining Co., Ltd.", it was not a long time, and Chen Guan did not have the opportunity to learn more about the history and current situation of the gold industry, let alone in-depth study and research on mining and smelting technology. Today's trip to the Shuiquan Gold Smelter is equivalent to touching the door for Chen Guan, and if he wants to enter the threshold, he has to soak in it for a period of time and taste the bitter and sweet of being a mine boss. Otherwise, he is likely to only see mining bosses like Guo Zhanshan making a lot of money, and not see the sadness behind them!

Zhang Qing told Chen Guan that Sangyuan and Linguan both belong to the remnants of a mountain system, and there was only state-owned gold mining in the past, and later, the top leader at that time came here to inspect, and heard that there were gold mines in Sangyuan, but local and private mining was not allowed. At the end of this, the people of Sangyuan rushed to the mine like crazy, and the county set up a local gold mine, and all units went up the mountain to open mines, and more private mines were opened. Fortunately, this is one of the largest ore veins in China, with wide ore lines, thick ore layers, stable, and the most suitable for continuous mining, it is said that the rich ore grade is generally about 40 grams, and some grades are as high as 200 grams, 400 grams, or even more! What a golden mountain from God! It's a pity that the current smelting technology is not up to par, the technology is backward, and the price of gold is low in the past few years, more than 30 yuan a gram, and the ore with a grade of less than 20 grams is not mined, and it is not profitable! It's a waste of waste! Maybe in ten or eight years, the rich ore will be exhausted, the resources will be exhausted, the smelting technology will be improved, and the process will be improved, and these miners will have to go back to dig less than 20 grams and 8 grams of ore, and may dig out the tailings and re-smelt them!

Zhang Qing is right, more than ten years later, the mining industry in Sangyuan and Linguan is really like this, and the ore with a grade of 2 grams has become fragrant and can't be grabbed! Some gold companies have no choice but to go to remote provinces for prospecting, mining, and even to Africa for mining! It's a pity that Zhang Qing and Chen Guan are not traversers, and they don't know what will happen after Lu Dao, so they can only talk about things and sigh with emotion!

After blowing so much, Zhang Qing summed it up: "As long as the test results come out that your ore grade is really 40 grams, you will become rich, a millionaire, a multimillionaire!" ”

Chen Guan smiled bitterly, saying that he had been fighting at the mine for a long time, and he had not seen the mine after two bosses, saying that he had stopped the black hole, and he couldn't afford to raise his pants if he lost money, where could he get rich! This is just the mine, and it is difficult to say whether you can earn back the investment!

Zhang Qing said with a smile, as long as the bonanza is stopped, no matter how much you lose, you are not afraid, and you can earn it back soon! In recent years, the price of gold has soared, in 89 years, the purchase price of the People's Bank of China was still 48 yuan per gram, in May 93 it rose to 53 yuan per gram, in September it rose to 96 yuan per gram, and this year it fell slightly back. Look at this trend, it won't fall in three or five years! Even if it falls again, it is impossible to fall back to 50 yuan per gram.

Chen Guan agrees with Zhang Qing's opinion! It's just that he heard Guo Zhanshan say that the Yangshan mine is a chicken nest mine, one nest after another, and he doesn't know how long this mine can be opened!

Chen Guan asked Zhang Qingzhi if there was a chicken nest mine in the mines of Sangyuan and Linguan?

Listening to the accent, Zhang Qing should have come from the Northeast, and his working time should not be short.

Zhang Qing said that he was in contact with the mine bosses every day, and as far as he knew, the main veins in Sangyuan and Linguan were not chicken nest mines. If it's a chicken nest mine, it's definitely not the main vein! When it comes to chicken nest mines, there are big and small. The large chicken nest mine can produce tens of thousands of tons and thousands of tons of ore; A small chicken nest mine can produce hundreds of tons of ore. If you are lucky, after digging a nest, the ore veins will loom, and then carry out tunnel excavation, and you can also encounter the next nest of mines. If you're unlucky, you may be completely gone after a nest of mines!

When Chen Guan heard this, he felt a little deflated. Because this is the case with Guo Zhanshan's mine, the veins have become extremely thin now. But after thinking about it, Cangshengyin is absolutely reliable, and his mine mouth is better than Guo Zhanshan's geographical location, maybe the last to come first, is a main ore vein!

Chen Guan saw that Zhang Qingren was very enthusiastic, and he was also a salesman in a smelter, and he had a lot of contact with mine bosses and a lot of understanding of the situation, so he asked tentatively: "Manager Zhang, do you know what is the price of ore sold at the mouth of the general mine in Ludao?" ”

Chen Guan is the mine boss, but in turn he asks the smelter salesman, the most private question of the mine boss, is it simply a slap in the face!

No way, although Wang Yunlai has been mining for a long time, he has never sold ore! Guo Zhanshan is a fine man, but this is a secret of others, so don't say it easily! Jiao Tiande They are engineers, they only care about mining and don't operate, and Chen Guan doesn't know other mine bosses, so he just took the opportunity to ask Zhang Qing!

Zhang Qing smiled and said nothing!

Chen Guan hurriedly took out a cigarette, gave one to Zhang Qing, took out a lighter and lit it, smoked one himself, put a box of cigarettes on the table, and said respectfully: "Manager Zhang, I just saw the mine, I don't understand anything, I have to rely on your guidance!" ”

Everyone has the habit of being a good teacher, Chen Guan is so respectful and sincere, and Zhang Qing is not the boss of the mine, what else can not be said?

Zhang Qing smoked a cigarette and said: "As far as I know, as long as it is a gold mine of a certain scale, the ore has to be sent to the selection site, and the gold concentrate powder is sent to the smelter, and there is no problem of selling ore at the pit." In the past, it was very cheap to sell ore at the mouth of a private mine, but it has risen to 30 yuan to 40 yuan per gram in the past two months, that is, a ton of 40-gram ore can be sold for 1,200 yuan to 1,600 yuan. A car can weigh up to 18 tons, which is equivalent to a car of mine can be sold for 21,000 to 28,000 yuan. If you have more, you can't sell it, because you have to pay for the freight when you buy the mine, and you have to pay for the transfer of the mine and other expenses when you go down the mountain. ”

With this statement, Chen Guan's mining cost came out. Because his mine was mined by a large package for the migrant labor team brought by Wang Yun, the contract clearly stated that when the roadway was built, it was calculated according to the footage, 800 yuan per meter; After seeing the mine, it is calculated according to the tonnage of ore, 100 yuan per ton. Other taxes and management fees will not be known until they have been paid once.

Chen Guan is like a primary school student, he wants to ask everything!

Just after asking about the price of selling ore at the pithead, Chen Guan asked again what procedures are required if you come to sell gold concentrate powder?

Zhang Qing immediately took another feeding process and explained it to Chen Guan one by one.

After hearing this, Chen Guan understood that if there was gold concentrate powder, it needed to be sold to a gold smelter, or it should be processed by a gold smelter, and a contract had to be signed first. Before delivery, you have to call to inform and report the grade and quantity of gold concentrate powder self-inspection, because the feeding time of the gold smelter is from 8 am to 4 pm, and the car is not allowed to feed the yard at other times. After the car arrives at the material yard, it has to go through several main links of weighing, counting pounds, taking arbitration samples, and laboratory sampling. Among them, it is very important to take arbitration samples, if the gold concentrate powder manufacturers are not satisfied with the test results of the smelter, they have to rely on the arbitration samples to coordinate and solve. And the test of the arbitration sample was not carried out in the water spring, but in the ancient capital.

As soon as Chen Guan heard this, he immediately realized that if he wanted to come to the smelter to sell gold essence powder, he had to think about getting to know the laboratory technician. Otherwise, if the test grade is 1 gram lower, it will be a big loss!

Everything that should be asked has been asked, and Zhang Qing has said everything that should be said! Chen Guan compared it in his heart, and felt that if the ore grade was high, it would be more cost-effective to engage in processing with supplied materials. Unfortunately, the Shuiquan Gold Smelter only collects gold concentrate powder and does not accept primary ore.

Chen Guan, who did not give up, asked Zhang Qing again, is there a smelter integrating mineral processing and smelting in the area of Sangyuan and Linguan?

When he met a layman, Zhang Qing could only patiently tell Chen Guan that there are three main methods of gold smelting, namely fire gold extraction, wet gold extraction, and electric gold extraction. The fire method of gold extraction is a thing done by ancient people, and it has long been used; The electric method of gold extraction consumes a lot of electricity and has a high cost, and it is basically not used. We are now using the smelting method of wet gold extraction. The simplest way is to buy a mill to crush ore, pull the wire, use the mill to crush the ore, add cyanide, select the mercury paste through the mercury plate, and then melt the mercury paste with a crucible, add silver to purify it, and get a gold nugget. But this method is too simple, the gold recovery rate is too low, 20 grams of ore, can be refined out of 12, 3 grams is good, not to mention the associated silver, copper, zinc, iron, sulfuric acid and other minerals in gold ore, the loss is too great, and the purity of the refined gold is not enough, it is good to reach 95% pure gold! Some mines, the gold grade is not high, but the silver content, copper content is high, still make a lot of money, if you let the small mill choose, it will be all wasted, and you have to lose money!

Chen Guan would never go to open a small mill, so he nodded straight when he listened!

Zhang Qing said that the more advanced methods are those small smelters, the investment is not large, and the main equipment is also crushing, ball milling, flotation equipment, they can select gold concentrate, but also the associated silver, copper and other minerals together, all contained in the gold concentrate, and then refined. However, due to equipment, technology, technology and other reasons, these small smelters can often only extract gold, and other associated products are difficult to select, and most of them are dumped as tailings. In addition, even the purity of small smelters does not meet the standard of 999 pure gold. Therefore, most concentrators will send the gold concentrate to the Shuiquan smelter for smelting.

Zhang Qing said very clearly, you can choose and refine the rich ore anywhere, but you can go to the small smelter to lose a little more profit, and you can still make money. Poor mines are different, they must be smelted by large smelters, otherwise they will have to lose money! Foreign ore with a grade of more than 2 grams, after beneficiation, the grade of gold concentrate powder can reach 12 grams to 15 grams per ton, and after smelting in a large gold smelter, the gold recovery rate is high, plus silver, copper and other by-products, and profitable!

Chen Guan thought about it, or have to run their own concentrators, preferably to run a large-scale smelter, in the future beneficiation, smelting integration, in order to truly worthy of the "Jinyangshan Mining Co., Ltd." signboard.

However, at present, this can only be imagined, the Yangshan mine has just seen the mine, and it has to wait until a lot of money is made before considering the construction of a large concentrator and a large smelter. For the time being, you have to go to Linguan or Zaoyuan to negotiate with the concentrator, you have to pull the ore to select, select the gold concentrate powder and send it to the smelter for smelting, so that you can not waste resources, the purity of the selected gold is also high, and the income can be maximized!

If you build a small concentrator, I don't know if the investment is big or not, and whether it is feasible!

Zhang Qing told Chen Guan that there is a gold design institute and a gold machinery factory in Shuiquan City, and it is not a problem to engage in small site design! If Chen Guan goes to them, they will definitely be very active in helping!

This trip Chen Guan consciously gained a lot of gains!

Seeing that it was already time to get off work, Chen Guan invited Zhang Qing to have dinner together.

It's a pity that Zhang Qing needs to be on duty and can't leave, so he said that Chen Guan will see him again tomorrow after taking the test results!
