China is a big graphite country, and Heilongjiang Province is a big province of graphite. Jixi and Hegang in Heilongjiang Province are rich in graphite resources. Among them, the prospective reserves of graphite resources in Jixi are 850 million tons, accounting for 57% of Heilongjiang Province, accounting for 38% of the country, accounting for 21% of the world. Therefore, the graphite industry pollution control, Heilongjiang is the top priority.
Regarding the status quo of pollution control in the major provinces of graphite, the main problems and the latest developments, the reporter of China Chemical Industry News has interviewed the regulatory authorities and production enterprises of Heilongjiang Province this week.
Pollution control standards and regulations are becoming stricter
The reporter of China Chemical Industry News learned from the Heilongjiang Environmental Protection Department that during the process of mining, production and production, graphite will produce substances that affect the environment such as dust, smoke and tailings. Among them, dust is the largest source of pollution in the graphite industry, followed by smoke and tailings pollution. Due to the lack of clear industry norms, the industry barriers are low, the industry's technical level and economic returns are not high, and the environmental pollution problem in the graphite industry is outstanding. Such as the destruction of abandoned mining sites, waste rock, dumping of waste, discharge of wastewater, etc., polluting the surrounding land and surface water system, seriously destroying the ecological environment of the mining area and affecting the production and life of the surrounding residents.
The relevant person in charge of the Environmental Protection Department of Heilongjiang said that the Heilongjiang provincial government, relevant departments and enterprises are constantly introducing new technologies to reduce the pollution of graphite to the environment. In 2012, the “Graphite Industry Access Standards†issued by the Ministry of Industry and Information Technology listed environmental protection as one of the five conditions, including strict implementation of environmental impact assessment and “three simultaneous†system, and five access conditions including dust suppression and dust removal facilities. The city of Jixi and other cities in the province also pays great attention to the coordination with their own ecological environment, correspondingly promotes the access of the graphite industry, improves the production scale, production technology and technological level of graphite enterprises, implements clean production, and does not control pollution enterprises and “three wastesâ€. "The implementation of emissions that are not up to standard is shut down and treated within a time limit.
The six measures recently introduced in Heilongjiang Province seem to be not directly related to environmental pollution control, but in essence each one points to environmental pollution control, which has tightened the clockwork for graphite pollution.
Clean production companies have acted
The key to eradicating the environmental pollution of the graphite industry lies in the production enterprises. The reporter of China Chemical Industry News dialed the phone number of Xu Shu, general manager of Jixi Fuxiang Graphite Co., Ltd. Xu Shu expressed full support for the six major initiatives. He said with confidence: "Our company has invested about 45 million yuan in plant renovation, equipment renewal and technology introduction in recent years. Last year, five new dust and soot treatment equipments were added. After the operation, the effect is very good. Well, there are currently two dust and soot equipments that are being installed and ready for use within the year, so there is no problem with dust and soot treatment."
“As for the treatment of tailings, our company has no problem. Our approach is to discharge 70% of the tailings water into the tailings pond, and then return to the production workshop after sedimentation to form a closed loop to control the tailings water discharge and reduce Environmental pollution," Xu Shu said.
Heilongjiang Aoyu Graphite Group is an early-stage graphite enterprise. It has become a well-known enterprise integrating mining and deep processing in Heilongjiang Province and China. In 2010, the group put into operation Guangsha New Material Brick Co., Ltd., and blended the mined tailings produced with local coal resources to produce energy-saving and environmentally-friendly hollow bricks, filling the gap in the industry.
Han Yufeng, chairman of the group, said: "We have been advocating the integration of graphite resources, not only to fully utilize and play our valuable graphite resources, but also to reduce environmental pollution caused by disorderly mining. The governance environment proposed by the Environmental Protection Agency of Heilongjiang Province The six major measures of pollution can well supervise and promote the development of environmental protection and green direction in terms of intensive use of resources and accelerated upgrading. We are duty-bound to environmental protection."
Enterprises look forward to refining policies to deepen pollution control
The improvement of the threshold for entry conditions, the strict supervision of the government, and the self-discipline of enterprises have gradually standardized, formalized and rationalized the environmental pollution control of the graphite industry. However, if there is still a way to go to completely eradicate the environmental pollution of the graphite industry, the company has put forward its own ideas.
Han Yufeng suggested that we should start from the control of resources and intensify our efforts in intensive processing, and shut down and transfer to those mining enterprises with high energy consumption, low output and serious pollution.
Xu Shu suggested that the government and relevant departments thoroughly screen and resolve historical issues, such as resource certificates.
"Our company is a state-owned enterprise converted into a private enterprise. It is very difficult for its own graphite enterprises to operate. In addition, the company's resource certificate can not be completed, and the operation is even more difficult." He called for more technical transformation of dust removal equipment, and more development. Production of dust removal equipment for small and medium-sized enterprises.
“For example, we are using a bag-type dust collector. A larger dust collector needs several bags. These hundreds of bags will be replaced once in a month or two. The workload is heavy and the labor intensity is high. Previously, we I have also invested in spray and shower dust collectors, but the effect is not obvious. If we can develop and produce simple and suitable dust collectors that our small enterprises can afford, I think the environmental pollution problem will be greatly improved. Xu Shu said.

Main contents of the six measures
◠Increase integration efforts and efficiently and intensively utilize resources. Guided by local governments, we will further standardize the mining rights order and effectively integrate graphite resources. Heilongjiang Provincial Department of Land and Resources is working hard to draft and approve the "Special Plan for Graphite Resources in Heilongjiang Province". It is planned to integrate 36 mineral rights left over from history into 30 by the end of 2015, and integrate it into 25 by the end of 2020. The “four districts†management mode of key exploration areas, key mining areas, encouraged mining areas and prohibited mining areas shall be implemented to promote the effective protection, rational development and sustainable utilization of mineral resources.
â— Accelerate the upgrading and control of dust pollution. The environmental protection department will issue the pollution control facilities to the enterprise for rectification within a time limit, and organize experts to accept the rectification. The acceptance can be continued. The enterprises that failed the inspection or failed to complete the management tasks before September 1, 2014 will stop production.
â— Extend the industrial chain and break through the bottleneck of development. The Jixi and Hegang municipal governments should focus on the extension and expansion of the industrial chain, focus on the introduction of high-tech enterprises in graphite production, accelerate the upgrading and transformation of traditional graphite washing and processing, and realize the transformation of industrial structure from primary products to deep processing and products.
â— Implement protective development of graphite resources and improve access mechanisms. Control new additions, adhere to new construction and expansion and expansion of mineral processing projects (except tailings comprehensive utilization projects) new capacity and the elimination of backward production capacity. The design scale of the new and rebuilt and expanded scale graphite beneficiation project is not less than 20,000 tons/year, and the single-line scale is not less than 5,000 tons/year.
â— Strengthen the comprehensive remediation of graphite tailings to eliminate potential safety hazards. The safety supervision and inspection department shall continue to carry out safety supervision and inspection of the graphite tailings pond, do a good job in the examination and approval and issuance of the safety production license for the tailings pond, and close down the dangerous, diseased and dangerous reservoirs that are not in compliance with the requirements of illegal, unreasonable governance and governance.
â— Actively create a graphite green mine to improve the ecological environment. The land and resources department urges enterprises to speed up the open pit mining, slope renovation and vegetation restoration in abandoned land according to the green mine evaluation standards, timely dispose of various types of solid waste generated by mining, and ensure the safety of surrounding water bodies.
