"Brother Wei, your hospitality is already very high, if you hadn't taken it in, the two of us would have to sleep on the streets at night. Zhang Yi said with a smile.

Knowing that Zhang Yi was joking, even if he didn't live in Wei Ming's place, he could deal with it for one night in a casual guest house, Wei Ming said: "Okay, you don't have to be polite, since you come to the elder brother, you can rest assured, it's almost evening now, the two elder brothers wait a little, I'll arrange dinner immediately." ”

"Okay, then we're welcome. Now that he has made up his mind to cooperate, it will be polite to be polite, and Zhang Yi also wants to get closer to the relationship.

Liu Rui felt a little inexplicable, he felt that Zhang Yi's trip was completely unnecessary, but before going out, Professor Zhong explained that he could just listen to Zhang Yi if he had anything, so he didn't speak much when he came to Persimmon Bamboo Garden all the way.

Otherwise, in his opinion, why bother so much to get 1 ton of mine, just find Chenzhou Mining, give some money to get the mine, this is also a big detour, find a boss who resells ore to help.

Wei Ming's efficiency is also extremely high, and after just over an hour, not only did he prepare the room for them, but even made dinner.

The storefront on the first floor of the office building is for office use, through a corridor, behind which is the kitchen and dining room, the dining room is quite large, and there is a round wooden table painted with yellow paint in the middle, and there is no problem at all for sitting a dozen people.

At this time, there is a large pot in the middle of the table, and the charcoal is burning in the wind stove below, and the water in the pot is tumbling and steaming, constantly steaming up, and the pot is black and large pieces of meat, and the water vapor in the pot is steaming, and the specific meat is not clear, and there are a few fried side dishes on the table.

After Wei Ming beckoned Zhang Yi and the two to sit down, three more people came one after another, one was Qi Zhenghao, who was in charge of finance, and the other two were He Hua and Dong Jianping, who ran business.

plus Zhang Yi, Liu Rui, Wei Ming and Song Lin, a total of 7 people.

"The two brothers came at the right time, some time ago the wild black goats that were hunted on the mountain, the meat quality was very good, and they were usually reluctant to eat, so they dried and saved, and the two brothers came to take out the entertainment. Wei Ming pointed to the pot with chopsticks and said with a smile.

Zhang Yi looked at the goat meat in the pot that kept tumbling with boiling water, and suddenly moved his index finger, he had heard of the black goat in Persimmon Bamboo Garden, a very famous game, and he didn't eat it last time, Zhang Yi's chopsticks also moved, and said with a smile: "Thanks to my brother's blessing, we have a good mouth this time." ”

"Haha, you eat more, come often in the future, nothing else, the black goat is enough. Wei Ming said with a smile.

After starting to move the chopsticks, Wei Ming and others toasted with Zhang Yi and Liu Rui, He Hua and Dong Jianping, who ran the business, had the best amount of alcohol, these two were old rivers and lakes, and they were usually accompanied by various mine owners and bosses, leaders of mining areas or something, and it was not okay to drink poorly.

Where are Zhang Yi and Liu Rui opponents, Zhang Yi also learns to be smart, everyone is fighting with him, one at a time, so that he and Liu Rui have to lie down a few times.

Zhang Yi picked up the wine glass, and directly saluted the old brothers sitting at one time, a glass of wine was down, and Wei Ming and the others had to accompany six glasses, so that he didn't drink too much.

Liu Rui doesn't care so much, whoever comes is to do it directly, a glass to the bottom, a few glasses of wine to eat, Liu Rui also talked more, and began to talk about how he was doing a 3 million project in the laboratory, Zhang Yila couldn't hold it.

Just when Zhang Yi and the others were drunk, a person in his 30s walked in outside the restaurant, wearing a white shirt with gray trousers, a pair of shiny black leather shoes on his feet, and a briefcase under his armpits. ”

As soon as Wei Ming looked at the person, he hurriedly stood up and said, "What kind of wind blew you Director Yang over, come on, come on, hurry up and sit, isn't this the right time." ”

Director Yang was not polite, took a chair on the edge of the table and sat down, it seemed that he was quite familiar with Wei Ming and the others.

Song Lin hurriedly went to the kitchen and took another set of dishes and chopsticks.

After sitting down, Director Yang noticed that there were two more people, glanced at Zhang Yi and Liu Rui, and said, "The two little brothers are a little faceless, is it the first time to come to Persimmon Bamboo Garden?"

Wei Ming hurriedly introduced: "These two brothers came from Jiangcheng and wanted to come over to buy mines. ”

"Haha, it turned out to be your old Wei's gold master. Director Yang lifted his wine glass and smiled at Zhang Yi and the two: "Although the two little brothers can rest assured, Boss Wei is notoriously reliable, and it is definitely right to go directly to Boss Wei if you need anything." ”

Zhang Yi and Liu Rui also picked up the cup and touched a glass with Director Yang, and after saying some words, they killed it directly.

Seeing that the two of them drank all of them, Director Yang was also quite happy, which also gave him face.

A few people chatted while eating, knowing that Director Yang was encountering technical problems at hand, Wei Ming asked casually: "Old Yang, have you raised the index of lead-zinc mine?"

Director Yang is the director of the technology center of Weide Mining Company, which is a large enterprise in Persimmon Zhuyuan, with 5 or 6,000 employees, which is not comparable to Wei Ming's Tianshui Mining.

"Make a fart, this indicator is related to the nature of minerals, we have tried hundreds of methods, there is no progress at all, and if we can't do it, we will stop production. Director Yang directly burst into a foul mouth.

It is no joke that large mining enterprises stop production, the whole set of equipment starts to cost a lot, a factory is a whole, as long as there is a problem in one link, the whole plant will be affected, and the loss of shutdown is a huge number.

Wei Ming also seemed to know a little about the situation, and asked casually: "Isn't your lead-zinc mine still mined from that mine? How can there be such a difference in grade? There is no way to improve it." ”

"The mine has mined another ore layer, not the same ore layer, the grade difference is certain, and now the lead and zinc ore reserves in the mine are still very rich, and they must be utilized, but the technical problems cannot be solved, and if it goes on like this, it will be over, and I will be the director. Director Yang smiled bitterly.

"Director Yang, is your lead-zinc ore not able to raise the grade of concentrate after the beneficiation process?" Zhang Yi suddenly asked next to him.

He listened to it for a while, and also heard a little bit of the doorway, the problem that Director Yang encountered should be a very common problem in mineral processing scientific research later.

In the early days, the mines were all good ores, with higher grade and good quality, but as the mines were mined more and more, the remaining ores were either stratified and entered into other enriched mining areas, or the edges of the ore belts, mixed with many stones and other gangues, and the quality was much worse.

"Oh, Brother Zhang also understands this?" Director Yang said in surprise.

"I'm a technician in a smelter, and I've learned a little bit about this. Zhang Yi replied.

"I didn't expect Brother Zhang to become a technician at a young age, so does Brother Zhang have any ideas about my situation?" asked Director Yang.

"This should work out. Zhang Yi put down the chopsticks in his hand and said casually.

Director Yang shook his head, Zhang Yi is so young, even if he is a technician, he has just graduated from school, and he has not worked in the smelter for a few years, what level can he have.

The few people sitting there were also silent, obviously not listening to Zhang Yi's words.

However, Liu Rui had drunk a lot, and his eyes suddenly lit up when he was drowsy, how similar is this scene, when Zhang Yi said that he could solve the separation of tungsten and molybdenum, it was not the same as now.

"In fact, the lead-zinc ore grade problem can be easily solved by only applying selective grinding technology. Seeing that these people didn't seem to believe it, Zhang Yi said lightly.
