Yimen Copper Industry sets up Green Factory

SMM News: in recent years, Yimen Copper Industry led by party building, actively promoted Xi Jinping's ecological civilization thought to take root in Yimen Copper Industry. Nowadays, the green mountains, clear water, white clouds, gorgeous flowers, singing birds, neat factories, and enterprising staff have become a beautiful scenery of Yimen Copper Industry, which has deeply penetrated into the hearts of all the people of Yimen Copper and every guest who has been to Yimen Copper Industry for exchange, visit and research.

A heavy landscape and a heavy sky

Yimen Copper Co., Ltd. is located in Dachunshu Industrial Park, Yimen County, 89 kilometers away from Kunming. It is a non-ferrous smelting enterprise mainly engaged in the production of crude copper and sulphuric acid from smelting flue gas. In 1992, it was jointly built by Yimen Mining Bureau (now Yuxi Mining Company) and the government of Yimen County, covering an area of 790mu, with the original registered capital of 120 million yuan and the existing registered capital of 202 million yuan. After several equity transfers, it is now wholly owned by Yunnan Copper Co., Ltd. The smelting process adopts advanced oxygen-rich bottom blowing pool smelting and Pmurs converter blowing process, sulfuric acid adopts dilute acid washing purification, non-equilibrium pre-conversion pre-absorption and main conversion (two to two absorption) atmospheric contact acid production process, and tail suction adopts hydrogen peroxide absorption process.

After 27 years of reform and development, Yimen Copper has become a benchmark and star enterprise of Chinalco and China Copper. After five times of technological transformation, Yimen Copper Industry has embarked on the fast track of transformation and high-quality development. although it is small in size and small in scale, it has responded to an old saying: "although the sparrow is small, it has all the internal organs." Fully relying on the competitive advantage of differential technology and the concern and support of leaders at all levels, and through the unity and hard work of all cadres and staff, the company's safety, production, operation and profit objectives have been overfulfilled. Historic breakthroughs and improvements have been made again and again.

Since the 18th CPC National Congress, the party committee of the company has attached great importance to the construction of ecological civilization, deeply implemented the green development concept of "Green Water and Green Mountain is Jinshan and Silver Mountain", and put the improvement of enterprise ecological environment and the protection of employees' occupational health. Continuously enhance employees' sense of achievement and well-being as a primary political task. Through ecological restoration and environmental protection renovation in the past five years, the green area of the open space in the factory area has reached more than 70%, and the "three wastes" (waste residue, waste gas, waste water) of enterprises have reached the national super-net discharge target of environmental protection. It has been successfully promoted to Yimen County Garden Unit and Yimen County Health Enterprise. In 2016 and 2019, it was awarded a number of honors by superior companies such as excellent collectives of Chinalco Group. Outstanding achievements in safety, environmental protection and business performance have made outstanding contributions to superior companies and local economic development. Yu Dehui, deputy secretary of the party group and general manager of Chinalco Group, was crowned with the honorary title of "small and beautiful" enterprise.

Climb courageously through ups and downs

In 1995, Yimen Copper Industry was completed and put into production. At that time, there were two roads leading to the factory area, one is now Yi Tong Avenue, and the other is the present road of happiness. Both roads are dirt roads. Once it rains, the workers' labor protection shoes will be covered with red mud, weighing more than 5 kilograms. When workers commute from the factory area to the dormitory, they have to stop and find a small wooden stick to wipe off the red mud stuck on the soles of the shoes. Repeat seven or eight times to get to the destination. Today's new parking lot used to be an open space covered with barren grass, and there is almost no regular green belt in the whole factory area. Later, the company planted two rows of white wax trees on both sides of Happiness Road, retained the poplar forest in the upper section of Yitong Avenue, and planted rows of oleander along the factory area, and the environment of the factory area has been improved to a certain extent.

In the course of the development of the company, everything is centered on production and development. After several struggles and a narrow escape from death, finally in 2017, Yimen Copper Industry implemented the largest technical transformation project since the establishment of the plant-- 100000 tons of crude copper environmental protection, efficient and clean production transformation project was completed and put into production, making Yimen Copper Industry enter the national 100000-ton smelting enterprise entry threshold. The good, provincial, smooth and fast experience of the project has not only created the spirit of Chinalco and the speed of Yunnan Copper, but also been promoted and applied in the industry. One month after the project was put into production, it reached the production standard and made a profit of 146 million yuan that year, which helped Yimen copper industry embark on the road of high-quality development.

Draw a new blueprint for green copper exchange

To do a good job in ecological development is to develop productive forces. The technology has improved, the production capacity and profits have doubled, and the employees have become more energetic. The party committee of Yimen Copper Industry fully performs the central role of the party committee in guiding the direction, managing the overall situation, and ensuring implementation, uses the speculative thinking of party building to lead the development of enterprises, and regards green development as the main work after the completion of technological reform.

In the face of the new requirements of safety and environmental protection management in the new era, Yimen Copper Co., Ltd. has made an overall effort to do a good job in safety, environmental protection, and green development. The party and government team strictly implements the responsibility system of one post and two responsibilities, and actively advocates the work concept of unsafety, non-production, non-environmental protection and non-production. We have solidly promoted the work of safety and environmental protection and the construction of ecological civilization in the factory area, stepped up efforts to control low-altitude pollution, and successively implemented the converter ring collection flue gas transformation project. Sulfuric acid hydrogen peroxide desulphurization project and sulfuric acid dust collection bag project, secondary water treatment project, Ma Ganjing three slag prevention phase I to III project, slope treatment project, rain pollution diversion project, real-time dynamic monitoring of sulfuric acid tail gas.

Strengthen the theoretical arms, achieve the unity of knowledge and practice, and lead the high-quality development of enterprises. In 2020, the party committee of Yimen Copper Industry conscientiously implemented Xi Jinping's thought of ecological civilization, strengthened theoretical arms, always kept in mind social responsibility, and listed "the practice and application of Xi Jinping's thought of ecological civilization in Yimen Copper Industry" as the subject of party building and political research. carry out collective discussion, focus on doing detailed benchmarking work to further optimize the production index, realizing the production index of "two liters, four declines and one stable". Fundamentally reduce the production and discharge of pollutants; We will further promote the "four batches" projects, make up for the shortcomings of environmental protection, improve the level of environmental protection equipment, strengthen the publicity of environmental protection laws and regulations and environmental protection business training, enhance the environmental awareness of all staff, and achieve full participation in environmental protection management. Build a green garden factory, create "Yang Shanzhou demonstration forest" and "easy copper ecological forest" with two landmark green projects, and vigorously carry out the company's ecological restoration. Among them, "Yang Shanzhou demonstration Forest" is located in the back mountain of the company's slag flotation plant, covers an area of 21000 square meters, and began construction in 2019. At present, the green coverage rate reaches 75%, and it is planned to take three years to complete all the green area. "easy Copper Ecological Forest" is the company's raw water quenching slag field, which covers an area of 41000 square meters. Construction began in January 2020. In only half a year, the vegetation coverage has reached more than 50%. When the two ecological forests are completed, they will become two back gardens worthy of the name of the company, providing a strong guarantee for the creation of a green ecological factory.

To protect the ecological environment is to protect the productive forces, and to grasp the construction of ecological civilization is to strengthen the economic construction of enterprises. In the next step, Yimen Copper Industry will always maintain its original mind, forge ahead, grasp the ecological civilization construction of Yimen Copper Industry to the end with more pragmatic actions and more solid work style, and grasp the results and models. Constantly enrich the new connotation of "small and beautiful" enterprises!
