Chapter 182 The concentrator plant starts
Xu Cunren has been working all his life in the design of gold mines and concentrators, and he has both theoretical level and practical experience.
In the first part of the introduction, Xu Cunren mainly analyzes the distribution, economic conditions, and traffic conditions of the mines in the Tonghua Town mining area, as well as the transportation, water supply and power supply of the site selection of the East Tonghua concentrator, the transportation of tailings, the transportation of raw ore and concentrate products, the scale of the concentrator, the design indicators and products of mineral processing.
Among them, according to the design, after the raw ore feeds into the yard, 2K-10 type overhead electric locomotive is used to pull 20 units at a time1. The 2.3 meter fixed mine truck was transported to the workshop with a track gauge of 600 mm and a slope of 9%. A total of 3 electric locomotives are designed and one is spare. As for the design index, it is still the standard that Xu Cunren told Chen Guan last time, the raw ore grade is 4. More than 7 grams of flotation, the grade of gold concentrate after flotation reaches 127 grams per ton.
The tailings treatment adopts a trough flow device, which is directly washed to the tailings pond with water, and the backwater can be directly discharged into the Mingshui River after treatment to meet the national standards to avoid pollution problems.
In the second part of the engineering introduction, Xu Cunren first analyzed the ore characteristics and the content of various elements in the Yangshan gold mine of Jinyangshan Mining Co., Ltd., and believed that the maximum particle size of the raw ore is 500 mm, which is a medium crushable ore, with uniform embedding of fine grains and a low degree of mudding, which is an easy ore to be beneficiated. The water content of concentrate is less than 10% and the grinding fineness is 70%-200 mesh.
The process flow designed by Xu Cunren is as follows: the ore is ground and the gold concentrate is obtained by a single flotation method, and the separation process is one coarse, four fine and two sweeps, and the medium ore is returned in order, and the recovery rate is 89. 32%。 The pharmaceutical system implemented is: the inhibitor is lime, and the dosage is 0. 8kg/t; The collector is xanthate, and the dosage is 0. 13kg/t; The foaming agent is 2# oil, and the dosage is 0. 11kg/t。
Part after part, Xu Cunren spoke in detail and earnestly, and the experts, factory bosses, and technical personnel attending the meeting listened to it from the heart.
This is a complete and innovative concentrator design scheme, which is much more advanced than the current concentrator plant in Sangyuan and Linguan mining areas, both in terms of process flow and equipment.
Xu Cunren spoke for two hours and explained the design plan thoroughly.
The participants in the meeting listened and looked at the copied design plan in their hands, and they didn't even cough from beginning to end, for fear of affecting Xu Cunren's explanation.
After Xu Cunren finished speaking, Chen Guan already had a clear understanding of the entire Dongtong Flower Concentrator!
Chen Guan is not stupid or stupid, he can understand what Xu Cunren said, and he understands it much faster and deeper than others. Because after he was washed by the Cangsheng Seal, he was also instilled with a large amount of information by the Cangsheng Seal, which made it easier to understand!
Xu Cunren's design plan is an overall design plan, including the work system of each workshop, shift change are clearly stipulated, and the standard systematic and factory operation. With this design plan, not only the construction of the Dongtonghua concentrator plant has a basis, but also the normal production and management after the completion of the plant has a basis, just do things according to the regulations.
At this moment, Chen Guan was glad that he insisted on how correct this argument was!
Chen Guan studied Chinese and knew nothing about industry. After participating in this demonstration meeting, Chen Guan felt that he had a relatively complete understanding of industrial projects. In the future, even if he is allowed to grasp the industry, he will not be afraid. At the very least, he understands the principles and methods of industrial project design, as well as the key aspects that need to be considered.
None of the experts attending the meeting disagreed with Xu Cunren's design plan, and some were just amazed!
The only one who made some suggestions was an operator from a concentrator in Mulberry Garden.
The operator's suggestion is actually only a minor change at the operational level, which requires an extra sieve to be added to the mill and flotation machine in the grinding and flotation process. The reason is that the sieve is easy to be damaged, and changing the sieve delays the operation time and affects the work efficiency.
This operator is a front-line worker who is thinking about improving work efficiency.
After hearing this, Chen Guan drew inferences from one another, and immediately thought that one more sieve could improve the gold recovery rate!
Chen Guan told Xu Cunren his idea and asked him to ask the equipment manufacturer to improve!
Later it turned out that it was the addition of a sieve that allowed the flotation recovery rate of the Dongtonghua concentrator to break through the 92% mark.
The demonstration meeting went so smoothly that Cui Ying, secretary of the Party Committee of Tonghua Town, who presided over the demonstration meeting, was overjoyed, and repeatedly expressed her gratitude to the Shuiquan Gold Design Institute for doing a lot of work in the early stage.
Chen Guan made a very generous move this time, let his parents and Li Ping buy a batch of leather briefcases and high-grade water cups in advance, and the water cups were specially sprayed with the words "Jinyangshan Mining Co., Ltd. Dongtonghua Concentrator Design Scheme Demonstration Meeting Commemoration", the guests who participated in the meeting each had a black leather briefcase worth 300 yuan, and a high-grade water cup worth hundreds of yuan, which looked very high-grade, and it was equivalent to advertising Dongtonghua concentrator in advance.
Guo Zhanshan was invited by Chen Guan to also participate in the demonstration meeting.
Unlike Chen Guan, Guo Zhanshan never had the idea of making the mining bigger and stronger in his mind. He thinks that opening a mine is opening a mine, as long as the mine is dug and can be sold for money, what kind of concentrator can be done!
Guo Zhanshan felt that Chen Guan's engagement with Jinyangshan Mining Co., Ltd. was purely to lose money and make money, and toss blindly! The mining itself is afraid that the tax department will stare at the tax inspection, Chen Guan is a simple man, and he also took the initiative to send it to the door, and he is to apply for a license, and to engrave the official seal to receive the invoice, isn't that looking for tax money to the tax bureau?
What Guo Zhanshan didn't expect was that Chen Guan had just established a Jinyangshan Mining Co., Ltd., and as soon as the Yangshan mine saw the mine, he began to build a concentrator again. It is necessary to know that the concentrator plant is different from the mine, this is pure industrial production, each workshop and team are interlocking, the management is strict, the accounts are clear, and the cost accounting is impossible!
That's one thing.
On the other hand, the last time Chen Guan's Jinyangshan Mining Co., Ltd. was unveiled and the Yangshan Gold Mine resumption ceremony was a great shock to Guo Zhanshan, allowing him to see the difference between Chen Guan's mine and his. That is, as soon as Chen Guan's mine mouth came up, it was so powerful that ordinary people did not dare to covet it; In the eyes of others, his mine is just a private mine, and there must be a mine protection team to protect the mine 24 hours a day.
Participating in the demonstration meeting this time, the sense of shock that Chen Guan brought to Guo Zhanshan was still fermenting, and he had already understood that the selection factory run by Chen Guan was different from those small private elections in Linguan. If this concentrator is completed, maybe the town and county will support it, and regard this concentrator as a key enterprise in the county and town!
Guo Zhanshan suddenly felt that Chen Guan was very clever!
Tao Haishan is a writer and is the best at discovering information.
As soon as the demonstration meeting ended, Tao Haishan personally wrote a piece of information entitled "The Design Plan of Dongtonghua Concentrator Plant Passed the Demonstration", and faxed it directly to the information publications of the county party committee communication group and the county party committee and county government office.
Mingshui's economy is underdeveloped, and there are few industrial projects. As soon as Tao Haishan's information was released, the information publications of the county party committee office and the county government office were edited and printed in the afternoon of the same day, and directly sent to the desks of the leaders of the four major groups. Only then did the leaders of Mingshui know that Tonghua Town was about to give birth to a medium-sized concentrator.
The secretary, the county magistrate, the deputy secretary, the executive deputy county magistrate, and the deputy county magistrate who grasped the industry called Tonghua Town one after another, looking for Cui Ying to understand the situation, asking about the start date, and urging us to increase the work to ensure the smooth implementation of the project and contribute to the increase of Mingshui's financial revenue.
This matter is obviously Chen Guan invested in the concentrator in the name of his parents, with the purpose of making money for himself, but it has become a government act. Except for the non-investment of the finance, Chen Guan doesn't need to worry about other things, the government is pushing him forward, he can't think of projects, he can't make money!
After the demonstration meeting, Xu Cunren's design plan was approved. Chen Guan immediately transferred 500,000 yuan to Shuiquan Gold Design Institute, the contractor of the Dongtonghua concentrator project, and paid off the first project payment.
The payment is so neat, which once again shows that the construction funds of Dongtonghua concentrator have been put in place, and there is no problem that the project payment cannot be settled.
Xu Cunren was completely relieved, and immediately notified the representatives of the civil construction party who came to Tonghua Town with him, and quickly organized the construction machinery and construction team to enter the site and engage in three links and one leveling.
The construction team is afraid that they will not be able to find a job and get the project, and they are afraid that they will not be able to pay for the project after completing the work. Now the Dongtonghua concentrator project is about to start, and there is no problem with the project payment, so the efficiency is naturally extremely high.
At 10 o'clock in the morning of the next day, Cui Ying, Secretary of the Party Committee of Tonghua Town, and Tao Haishan, the mayor of Tonghua Town, led the cadres of various departments directly under the town, and the villagers of Dongtonghua Village and the civil construction team to hold a simple commencement ceremony at the site of Dongtonghua Concentrator in the north of Dongtonghua Village.
Cheng Wenxi, the party secretary of Dongtonghua Village, and Cheng Wendao, the village head, waited at the scene early and organized the villagers to beat gongs and drums and set off firecrackers at the scene.
At this time, Cui Ying has the demeanor of a husband and a heroine in a middle school.
After the groundbreaking ceremony began, Cui Ying said in her speech that Tonghua Town should develop the gold economy based on the mine and strive to rank among the top 10 in the city's township GDP. Today's start of the East Tonghua concentrator plant, is the future of Tonghua Town's economic take-off of the leading geese, Tonghua Town's financial revenue can have a qualitative leap, depends on whether the plant can be completed and put into operation as soon as possible. Therefore, the whole town, starting from the secretary and the mayor, has only one central work at present, which is to fully support the construction of Dongtonghua concentrator plant of Jinyangshan Mining Co., Ltd. No unit or person shall obstruct the construction of the project or affect the progress of the project for any reason, and the offender will be held accountable and will not be soft!
Cui Ying asked Jinyangshan Mining Co., Ltd. to concentrate financial resources on the construction of the concentrator plant to ensure that the funds continue to be filed, and to ensure that the progress of the project is not affected. At the same time, Cui Ying asked Jinyangshan Mining Co., Ltd. to start recruiting and training employees from now on, so that they can be familiar with the working environment, work process, and equipment performance as soon as possible, so as to ensure that the project construction can be put into production quickly.
After Cui Ying finished speaking, she broke ground for the Dongtonghua concentrator together with Xu Cunren, president of Shuiquan Gold Design Institute, Tao Haishan, mayor of the town, Zhang Lei, deputy secretary, Qin Huaisheng, deputy mayor, and Chen Guan, director of the police station!
The Dongtonghua concentrator project has started!
