Environmental protection is a basic national policy for China's modernization. The Chinese government has enacted the Environmental Protection Law, and various departments have accordingly formulated relevant environmental protection regulations and regulations. China's environmental protection is based on the principle of "comprehensive planning, rational distribution, comprehensive utilization, turning harm into profit, relying on the masses, everyone's hands, protecting the environment, and benefiting the people", adhering to comprehensive prevention and control, prevention and control, and combining prevention and control. To promote governance, who pollutes who governs the principles. According to the different ecological and environmental conditions of the local infrastructure projects, on the basis of doing a good job in environmental impact assessment, the provisions of “Environmental Protection Design and Main Engineering Simultaneous Design, Simultaneous Construction, and Production at the Same Time†should be earnestly implemented. Key beneficiation plant environmental protection is to prevent the production of sewage generated, dust, noise tailings and environmental impacts and hazards. Lead-acid Electric Motorcycle durable, electric motorcycle manned significantly accelerated acceleration, turning flexible, the battery is in use for some time there will be some active material sink, if the active material is not activated in time, it is bound to cause the battery capacity Some impact, therefore, in the regular use of electric vehicles, to do a quarter of the battery deep discharge once. Affordable, convenient and environmentally friendly. Can greatly reduce the consumer's late use and maintenance costs.

In the concentrator design and beneficiation tests, the following aspects related to environmental protection must be given adequate attention and take appropriate measures to comply with the relevant provisions of metallurgical enterprises environmental design:
(1) The site and overall layout shall minimize the impact on nearby residential areas, agriculture, atmosphere, water system, aquatic resources, groundwater, soil, soil and water conservation, animals and plants. Meet the requirements of environmental protection, set up appropriate protection zones, and consider the greening environment.
(2) The mineral processing technology is as non-toxic as possible when the technology is economically reasonable. The effluent of the concentrator should first consider recycling as much as possible or use more water, and reasonably improve the recycling rate of water. When it must be effluxed, it should be treated according to local conditions to meet the specified emission standards. For the discharge of waste water containing harmful substances such as cyanide, purification treatment should be used in advance to remove harmful substances such as cyanide. The flushing floor and dust-removing sewage are also not arbitrarily discharged and can be sent to the process system for reuse or sent to the tailings pond.
(3) The ore dressing plant must have a perfect storage tailings facility. The tailings reservoir site should consider the protection of natural mountain forests, ground and groundwater systems, and it is strictly forbidden to discharge tailings into rivers, lakes and seas. Where conditions permit, the comprehensive utilization of tailings or filling of pits may be considered. After the tailings pond is full, it should be considered to cover the soil and vegetation. For the tailings that can produce sand, the dust-proof measures should be adopted.
(4) Measures should be taken to prevent the spread, loss and leakage of tailings containing toxic or radioactive materials.
(5) For the operation of excessive noise in the factory, effective noise reduction and sound insulation measures should be taken as far as possible.
(6) It is necessary to evaluate and stipulate the pollution caused by the construction project and the impact on the environment, and the environmental impact report shall implement the examination and approval system.
The environmental protection design of the concentrator shall implement the relevant standards promulgated by the state such as: atmospheric environmental quality standards, surface water environmental quality standards, seawater quality standards, comprehensive wastewater discharge standards, surface water quality standards, exhaust emission standards, and the highest levels of hazardous substances in the air of the workshop. Allowable concentration, noise standards for industrial enterprises, etc.
