After Zhang Deqing finished speaking, Mayor Yu Chen delivered a speech on behalf of the Shuiquan Municipal Party Committee and Municipal Government!

Mayor Yu said that the completion and operation of the Dongtonghua concentrator plant is a memorable event in the history of the development of the Shuiquan gold industry. Although Dongtonghua concentrator is only a medium-sized concentrator with 500 tons of gold ore per day, it has advanced equipment and high technology content. After the concentrator is put into operation, all 4 grams of poor ore that has no mining value in the past can be flotated with a content of 4. For 7 grams of ore, the grade of gold concentrate can be as high as 127 grams per ton after flotation! This is a great breakthrough, in the city, the province, the national gold refining industry, in the leading position! Congratulations!

Mayor Yu went on to say that the Municipal Party Committee and Municipal Government have formulated a development strategy with the gold industry as the leader and the five industries of manufacturing, textile, pharmaceutical, tourism, and forestry and fruit industry simultaneously. Whether this strategic pattern can be realized, and whether Shuiquan can become a strong economic city in the province in the future, the key lies in whether the leading industry of the gold industry can play a leading role! Therefore, it is hoped that the cadres and workers of the golden front will brace their spirits, reform and innovate, and strive to achieve the goals issued by the municipal party committee and the municipal government!

Yu Chen was pragmatic, when talking about the Dongtonghua concentrator, he particularly emphasized the need to rely on the development of gold refining technology, continue to explore, engage in technological innovation, do everything possible to improve the flotation rate of gold ore, do everything possible to improve the gold recovery rate, do everything possible to improve the grade of gold concentrate powder, do everything possible to improve the modernization level of the production line, and do everything possible to ensure that the environment is not polluted.

The speeches were all written in advance, and Yu Chen finished the speech in five minutes on a thin two-page paper.

There were many people who attended the ceremony, and some people couldn't hear the leader's speech, and some even went in and out of the left ear, and returned the content to the leader. Chen Guan is different, he is in the learning stage, listening to the leader's speech is hungry, eager to engrave every word in his mind and digest it into his own things. Including the calmness and calmness of the mayor's speech, it is what he has learned.

After Yu Chen finished speaking, according to the agenda of the ceremony, it should be unveiled and announced that the Dongtonghua concentrator plant was officially put into operation!

The voice of the host Mingyue was cheerful and loud: "Please Comrade Shen Quan, Secretary of the Shuiquan Municipal Party Committee of the Communist Party of China, and Comrade Yu Chen, Deputy Secretary of the Shuiquan Municipal Party Committee and Mayor of the Communist Party of China, unveil the Dongtonghua Concentrator of Jinyangshan Mining Co., Ltd." ”

The music of the military band sounded, Shen Quan and Yu Chen stepped on the cheerful tune, under the guidance of Miss Etiquette, walked to the left side of the factory entrance, and both hands moved, unveiling the red silk cloth on the copper nameplate of the Dongtonghua Concentrator of Jinyangshan Mining Co., Ltd., and the audience immediately applauded!

Immediately afterwards, Tantai Mingyue announced that he would like to ask the respected Secretary Shen to announce that the Dongtonghua concentrator plant was put into operation!

Shen Quan walked to the power switch on the marble pillar, faced the guests, and shouted loudly: "I announce that the Dongtonghua concentrator plant has officially started production!" ”

After shouting, Shen Quan reached out and pressed the power switch.

Suddenly, there was a roar in the factory area, and the Dongtonghua concentrator plant was put into operation!

The photojournalist captured this precious footage!

After the ceremony, according to the agenda, the leaders visited the Dongtonghua concentrator plant.

Chen Guan, Xu Cunren, and Kou Xun, the three of them walked in front and guided the leaders to the factory.

Chen Guan held a loudspeaker and introduced as he walked: "Leaders: Dongtonghua Concentrator has a total investment of 5 million yuan, with a total of four workshops: crushing workshop, grinding and floating workshop, filter press workshop and pumping station workshop, and a laboratory. The whole production process is as follows: after the ore is fed, it is transported to the crushing workshop by the 2K-10 type overhead electric locomotive traction stationary rail mine car, after crushing, it enters the grinding and floating workshop to add water and medicine for flotation, the water flows into the filter press workshop to remove the water and form gold concentrate powder, and the tailings are directly discharged into the tailings pond through the trough flow device, and the backwater is treated, which can be returned to the plant for industrial water, or can be directly discharged into the Mingshui River to ensure that it is not polluted. Please come with me, let's first visit the feeding process of the crushing plant. ”

The news reporters of the city TV station and the Mingshui TV station trotted all the way with the cameras and rushed to take pictures in front of the leaders.

The tour starts at the stockyard near the West Gate.

What appeared in front of the leaders was the scene of feeding materials to the crushing plant: a small railway, one end connected to the ore pile in the stockyard, and the other end led directly to the building of the crushing workshop. Next to the ore pile, two forklifts are working, loading the minecarts. Two 2K-10 overhead electric locomotives pull 20 1s one after the other. The 2-meter-3 stationary mine cart, after completing the loading, drove to the workshop.

Chen Guan said that the track gauge of this material conveyor is 600 mm and the slope is 9%. There are three traction locomotives in the factory, two working and one standby.

The picture of the mine truck transporting ore is very beautiful, and it is both beautiful and dynamic as a TV picture, and the reporters have pointed their cameras at the mine truck.

After entering the crushing workshop, Chen Guan introduced the model and performance of the crusher to the leaders, and then said: "There are 36 employees in the crushing workshop, one is two deputies and three workshop directors, divided into three teams, 11 people per shift, and implements an eight-hour work system, three shifts!" The working indicators are: the moisture content of concentrate is less than 10%, and the grinding fineness is 70%-200 mesh! ”

When the crusher was working, it was noisy, and Chen Guan quickly led the leaders into the grinding and floating workshop.

Chen Guan said that there are 33 people in the grinding and floating workshop, and they are also two and three workshop directors, divided into three work teams, 8-hour work system, and three shifts. There are 10 people in each shift, and there are three types of work: belt worker, ball miller, and flotation worker.

Immediately afterwards, Chen Guan introduced the model, performance and brand of the grinding and floating workshop and flotation machine to the leaders, and then introduced: "The process flow of the grinding and floating workshop is: 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 scans, and the medium ore is returned in sequence, and the design 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。 ”

Speaking of this, Chen Guan added: "When we were demonstrating the design plan, we took the advice of an operator and added an extra sieve to the mill and flotation machine, and found that the gold recovery rate exceeded 92% during the test run, which was much higher than the design standard of 89." 32%。 This indicator, as far as we know, currently belongs to the first in the country! ”

Mayor Yu Chen immediately asked: "Can this method be promoted in other concentrators?" ”

Chen Guan replied that he could definitely do it!

Yu Chen immediately instructed Chen Guan to do a good job in data recording and analysis, within one month, if the results are stable, the Gold Bureau will organize a visit to study and promote the technology, so as to promote the city's flotation industry to a higher level!

Chen Guan hurriedly reminded Mayor Yu that this was just a small process and could not completely change the flotation rate of the existing concentrator. The fundamental problem of the existing concentrator plant is that the process design is backward and the equipment selection is backward, resulting in no flotation value for ore below 20 grams. If you want to change the status quo, you have to work equipment renewal and process innovation!

Yu Chen knew that Chen Guan said to the point, and after thinking about it, he said: "In this way, it is not limited to one month, you do a good job of data recording and analysis, and I will let the Gold Bureau send someone here to track and analyze, if the process level and equipment level of Dongtonghua concentrator are really flotation more than 4 grams of ore, it will be carried out in a large range of equipment renewal and process innovation in the city." That's golden gold, once the flotation rate is increased, how much output value and profits can be increased! This is not a small account, it is a big account, and it must be calculated! ”

After entering the filter press workshop, many leaders who have never visited the concentrator plant understand that the production of the concentrator plant is inseparable from water from the beginning. Water needs to be added when crushing, water needs to be added when grinding and floating, and the gold concentrate after grinding and floating is almost liquid, and the water must be filtered out in the filter press workshop to be the real gold concentrate powder. The remaining tailings are washed to the tailings pond by the flow of water from the trough flow device!

There are a total of 12 people in the filter press workshop, working in three shifts, except for one and two deputy three workshop directors, there are only 3 people in each team.

The pumping station workshop is actually responsible for water supply and drainage and tailings treatment, and at the same time undertakes production and power supply, and there are 12 people, three people per shift, an electrician, an equipment maintenance worker, and an ordinary worker on duty.

When the leader's brain is very effective, Secretary Shen immediately asked: "Chen Guan, listen to your introduction, there are only 93 workers in the production workshop of the entire Dongtonghua concentrator. Isn't that too little? What if a worker gets sick or takes a leave of absence? ”

Chen Guan reported that if the workers on duty asked for leave due to illness, the director of the main and deputy workshops would go up. Moreover, Dongtonghua concentrator is also ready to accept internships from students from the Golden Technical School, and there is no problem with manpower.

After visiting the workshop, it was not early, and the stomachs of the leaders were rumbling with hunger. However, Secretary Shen and Mayor Yu insisted on looking at the tailings pond to see if they could ensure that the tailings water was indeed pollution-free after treatment, and that it would be a great sin to build a Dongtonghua concentrator plant and pollute a Mingshui River!

Chen Guan had no choice but to take the leaders to visit the tailings pond.

The tailings pond of the Dongtonghua concentrator plant is located in a deep ditch behind the plant surrounded by mountains on three sides.

The concentrator plant has just been put into operation, and it is only a little tailings discharged during the commissioning, and nothing can be seen at this time.

Chen Guanzhi said that for the concentrator, how to deal with tailings and tailings backwater is a big deal, the leaders are afraid of polluting the Mingshui River, with the leaders first stood at the mouth of the ditch to see the site selection of the tailings pond, introduced that the tailings pond can accommodate 2 million cubic meters of tailings, can be used for a long time, and then took the leaders to visit the water diversion project, the most focused on visiting the backwater purification equipment of the Dongtonghua concentrator, so that the leaders took a reassurance!

Originally, it was scheduled to start dinner at 12:40, because Secretary Shen and Mayor Yu insisted on seeing the tailings pond, and the distance was far away, and the time had already passed 12:40, and it was half past 1 o'clock.

Shen Quan said: "After reading it, rest assured, okay, the water flow is three feet clean, with such advanced purification equipment, Mingshui River is no problem, shouldn't we eat!" ”

Zhang Deqing hurriedly smiled and said: "Secretary Shen, I thought that the people who were big leaders were all steel and iron, so they didn't need to eat!" My stomach has been protesting for a long time! We have prepared a simple light meal, please get on the bus! ”

The leading convoy was parked outside the factory, but it had already driven in at this time, and the drivers were waiting in the car!
