Why are zinc industry projects one after another this year

since the beginning of this year, with the low price of non-ferrous metals rising, the zinc industry has become a beautiful landscape in development. First of all, let's look at the project dynamics currently in full swing: Xinjiang 600000 ton huoshaoyun project, Xinjiang Zijin zinc 100000 ton zinc project, Huludao 200000 ton zinc smelting project (expansion project), Tangshan Tenglong renewable technology Co., Ltd. 150000 ton zinc project of phase I of secondary resources Nanfang smelter plans to expand another 200000 tons of zinc smelting scale and Sichuan Sihuan Zinc Germanium reconstruction and expansion. The projects are all privately held. Although the progress of Xinjiang 600000 tons of fire cloud project has slowed down due to resource problems, these projects are being carried out in a tense and orderly manner. These developments show that there are not only many new projects, but also large-scale and highly concentrated

another hot spot is that on November 29, the relocation project of Zhuzhou smelter was officially launched. The existing production scale of Zhuzhou Smelter is 550000 tons, including 80000 tons of the fourth Shuikoushan plant, with a total of more than 600000 tons. Considering the constraints of construction investment, resource supply, allowable total amount of environmental emissions and other constraints, the scale was reduced to 300000 tons after relocation, truly realizing emission reduction and production reduction

we can see that under the high-pressure environmental protection policy, the most representative is that there were many small smelters in Shimian and Hanyuan areas of Sichuan Province. At present, these small-scale zinc smelters with disorderly competition are moving towards the edge of shutdown, and finally from "small disorder" to the development road of large-scale and environmental protection integration

under the background that the whole industry is not optimistic, the zinc industry in the non-ferrous metal industry has received a lot of attention and focus, especially the successive industrial projects. Behind these "zinc fever" phenomena, listen to the explanation given by liruogui, a design master and zinc smelting expert. Experts said that slight changes have taken place in the industrial pattern of zinc. First, the joint promulgation and regulation of national environmental protection policies are unprecedented, making it difficult for small zinc plants to survive and shutting down one after another; Second, with the rapid recovery of zinc price, the zinc smelting enterprises have created certain favorable conditions, and the enterprises began to invest funds to carry out technological transformation in the field of high environmental protection on the premise of profitability; Third, look at the future from the perspective of development, and eventually the smelter will move out of the city; Fourth, whether new projects or reconstruction and expansion projects, develop to areas with resources; Fifthly, while state-owned enterprises and private enterprises compete synchronously, private enterprises have taken a firmer and faster step in stability. Enterprises are scrambling to seize the opportunity. Even if the environmental protection standard is even higher, they are determined to strive for the sustainable development of advanced technology

under the guidance of the important concepts of green development and green water and green mountains are golden mountains and silver mountains, zinc industry enterprises have made ecological civilization the main melody of the development of the non-ferrous metal industry. Therefore, at present, no matter new projects, transformation projects or relocation projects are developing to large-scale, technologically advanced and resourceful areas. Therefore, while many enterprises seize the opportunity, large-scale projects break the silence

what are the advantages of the scale development of zinc smelting enterprises

experts believe that, first of all, from the perspective of development, it is the direction to develop into a smelting enterprise with environmental protection scale. Compared with small smelting enterprises, large-scale smelting enterprises have the advantages of advanced technology, good benefits, high environmental protection, relatively few pollution points, and greater energy conservation than small smelting enterprises. In addition, the experts made it clear that it is unrealistic to build smelting enterprises without any pollution and some emissions, but the emissions must be within the controllable range of national standards; Although small-scale smelters have small single total emissions, there are many pollution sources. When added together, the unit emissions will be very large

how to embody the resource advantage

the key is the overriding supply of raw materials. If an enterprise faces a resource bottleneck, even if it starts to pursue high-end equipment, the result will be the risk brought by "big horse pulling small car", and the inefficient operation of the equipment "not enough to eat" will not only be difficult to match the actual process requirements, but also waste energy resources and cause huge pollution. Shougang is a typical example, focusing on urban development, which is ultimately constrained by resources, environmental protection and other factors, Only then slowly began to develop to areas with resources

why did the smelter move out of the city

experts say that as smelting enterprises, no matter how they are treated, they are all polluting enterprises, just the size of the pollution. These enterprises will not take root in densely populated cities for a long time, which is inconsistent with the concept of green development, so they will eventually stay away from cities, at least keep a certain distance from cities

since then, experts have sorted out a very clear idea for the future development of zinc smelting enterprises. First, site selection is very important; Second, the process selection is the key, and the appropriate process must be selected for what kind of raw materials; Third, the treatment method of leaching residue should not be ignored. How to deal with it? Is it in compliance with environmental emission standards? At the same time, experts said that the large-scale construction of zinc smelting project is unlikely in the future. It is mainly to upgrade to advanced process transformation, and the threshold of environmental protection standards will be higher and higher. Only by reducing operating costs and improving production efficiency can we win development

it is undeniable that due to the lack of global economic growth power and the domestic capacity removal policy, the zinc smelting industry has only about 40 enterprises from more than 300 in the past, and nearly 20 enterprises with a high concentration of more than 100000 tons; There are nearly 10 enterprises with a capacity of more than 200000 tons, including Zhuzhou Smelter, Baiyin, Nanfang smelter, Huludao, Chifeng, Bayannaoer Zijin, Chihong Zinc Germanium, Bayi Hanzhong, Yuguang, etc. these enterprises have a scale of more than 200000 tons, and only these enterprises have accounted for nearly half of the total market volume of the zinc industry

from the above-mentioned enterprises, we can see that many of them belong to the category of large state-owned enterprises. With the continuous acceleration of new projects such as Xinjiang 600000 ton huoshaoyun project and Xinjiang Zijin 100000 ton project, private enterprises have flexible operating mechanisms, and their market development and innovation capabilities have been continuously enhanced. They have become an important supporting force for the industry. Finally, through continuous reform and exploration, these enterprises will strongly promote the innovation, transformation and development of enterprises, On the other hand, the gradual implementation and operation of these new projects will occupy half of the zinc smelting industry

among them, the distinctive feature is that some entrepreneurs have turned their attention to the use of secondary resources. Tangshan Tenglong 150000 ton zinc smelting project is the best explanation. This project is based on the fact that many steel ashes are wantonly disposed of by small workshop smelters, resulting in waste of resources and serious environmental pollution. On this basis, Tangshan Tenglong 150000 ton zinc smelting project is committed to high environmental protection standards. In order to cooperate with the steel plants in Tangshan and other places to implement supporting projects to deal with soot, and solve the environmental protection problem that has been difficult for steel enterprises to deal with slag, after the completion of the project, at least all the soot in Tangshan will be treated automatically, so that the pollution will not go out of the province and the region, and will be digested on the spot, In other words, zinc smelting enterprises reuse the so-called "waste" considered by the steel plant, so that they can eat it dry and squeeze it out. At the same time, they can return the iron slag to the steel plant, realizing cross-border innovation and win-win results. At the same time, it also ensures the maximization of resources. The viscosity and oil film thickness of lubricating oil play a very important role in reducing friction

we found that in the new round of scientific and technological revolution and industrial reform, private enterprises have actively expanded and immediately implemented the targeted direction. Looking back at the state-owned enterprises, the constraints are very practical and helpless. First, there are many burdens caused by historical reasons, such as huge institutions and redundant manpower; Second, most of these smelting enterprises are located on the edge of the city, which is extremely uncoordinated with the urban landscape. At the same time of pollution, the lack of resources has become the main factor

in the face of this, if you want to transform and expand, and want to start a new project, it is convenient and fast, but also faces capital constraints; What should we do if we do not transform the environment and fail to meet the standards? It is difficult for us to survive and it is even more difficult for us to achieve sustainable development? Many enterprises have to face the reality of relocation. So what are the real reasons for the relocation of these smelting enterprises? Why did many enterprises call for relocation many years ago, but in the end they were transformed on the spot

the effect of computer can be summed up to include the collection, transmission, response, analysis, display and printing of test data. First, urban planning is not synchronized with the construction and development of smelters. Urban planning lags behind the construction and development of smelters. That is, after the completion of the smelter, a pattern of cities surrounding the smelter has been formed. For example, the construction of Zhuzhou Smelter is still far away from the reality of the city and is surrounded by countryside, However, with the continuous development and expansion of the enterprise, high-rise buildings are erected, and the crowd is concentrated around the enterprise. Just as experts say, how can smelters be allowed to survive for a long time in the middle of the city? Finally, smelters can only move out of the city. At present, as a smelting enterprise of such a scale in the non-ferrous metal industry, it has to face the pressure of environmental protection. For the blue sky project, the enterprise finally promised the society to relocate the project to Shuikoushan, Hengyang, Hunan. It is understood that on the basis of summing up historical experience, the relocation project has completely focused on energy conservation and environmental protection from the beginning of its design, and truly achieved emission reduction, production reduction and investment reduction. Therefore, in the future design, the urban planning and the construction and development of the smelter should be considered as a whole

second, government orientation. In the future, the site selection should not consider the immediate interests unilaterally, but ignore the long-term development. It should not be a short-term behavior that is feasible for any project just to catch up with the project. After the project is completed, it is found that the selected site runs counter to the development

third, the relocation problem is huge and complex, which can be described as a big Mac project. It is not as simple as talking about relocation. First of all, employees' ideological unity is a difficult problem. In addition, there are a series of thorny problems such as family members going to work and children going to school. At the same time, after getting used to living in a certain area, employees will be moved to remote areas, which will lead to fear of difficulties in life; Secondly, smelting enterprises are different from mining enterprises. If mining enterprises have several professional personnel, the mines can be opened. Relatively speaking, there is no need to gather talents. Smelting enterprises are technology intensive enterprises, which need a large number of talent teams. Therefore, enterprises such as Shaoguan Smelter and Yunnan copper industry have discussed the relocation issue for seven or eight years, but they have not moved it. Instead, they have implemented on-site transformation

with the change of the new industrial revolution, what progress has been made in the smelting technology of the necessary factory testing equipment for zinc glass fiber reinforced plastic sand pipe in recent years? Experts said that there was no major breakthrough in the zinc smelting process at the technical level, but there was a bias in the understanding of the process at different times, especially in the treatment of leaching residue. With the continuous improvement of environmental protection requirements and the premise that leaching must be treated, once jarosite also lost its previous advantages. The other is the oxygen enriched leaching process. So far, neither atmospheric pressure leaching nor oxygen pressure leaching process has broken through the bottleneck problem of sulfur residue; Secondly, on the basis of the existing process, another problem restricting the development is also very difficult, that is, the high processing cost

in view of the restriction problems such as the treatment of leaching residue by traditional zinc smelting process, the state has made it clear that the treatment of leaching residue must be carried out regardless of new projects or expansion and transformation projects
