Phosphorus resources environmental protection
Phosphorus ore production process, produce large amounts of waste rock, waste, tailings, waste gas, dust and noise, so that around the mine water, air, soil contaminated, failure to take appropriate control measures, will destroy the ecological balance , affecting local production and life. Therefore, in addition to the implementation of the "Environmental Protection Law of the People's Republic of China" and related regulations, phosphate mine enterprises must also formulate relevant environmental protection rules and regulations according to their own characteristics and specific conditions.
Waste water
Wastewater comes mainly from phosphate rock mine engineering and drainage outside the open pit, waste mineral beneficiation plant, machine repair and auto repair water, living water. Mines should be treated according to the source and nature of the wastewater. The natural sedimentation|biochemical treatment process and secondary coagulation sedimentation treatment process can be used to treat the wastewater of the ore dressing plant to meet the discharge standard.
2. Dust
During the mining process, phosphate rock is subjected to dust explosion, mining, transportation and other processes, as well as in the process of beneficiation. The processes of crushing, screening and transportation are dusty, which seriously pollutes the work and the atmospheric environment. Therefore, effective dust-proof measures such as watering, spraying, dust removal systems, etc. must be taken to minimize the dust concentration at the operating point.
3. Noise
The mining, ventilation room, air compressor room, concentrating plant crushing, screening, dust removal, grinding system, etc. can produce noise in the production process, resulting in environmental pollution. First, we must establish noise regulations and noise standards for legal management. The second is to control and control the propagation and dissemination of noise sources, and take measures such as vibration control, sound absorption, sound insulation, and noise reduction.
In addition, phosphate rock should also strengthen greening and land reclamation to achieve the purpose of comprehensive management of the environment.
