The industrial waste gas, waste water and waste residue generated during the cobalt processing process are seriously polluted by the environment, among which SO2 flue gas, chlorine gas, acid mist, dust, waste residue and noise are the most harmful. In the past, due to lack of sufficient understanding of the protection of the environment, no due treatment was given. With the promulgation and implementation of the National Environmental Protection Law, people have a certain understanding of the importance of environmental protection work, and various enterprises have also set up special environmental protection agencies to take measures to control the "three wastes." Of SO2 gas governance Gansu Jinchuan Nonferrous Metals Company established recycling sulfuric acid plant SO2, eliminates SO2 gas diffuse phenomenon. The low-concentration SO2 produced in the nickel- cobalt smelting process is also effectively treated by processing into products such as sodium sulfite and ammonium sulfite. The amount of SO2 contained in the exhaust gas after treatment meets the national allowable discharge standard. Chlorine gas treatment The nickel and cobalt separation and exhaust gases contain chlorine gas, which is harmful to the human body. The Chengdu Electric Metallurgical Plant adopts the introduction of exhaust gas into the plastic corrugated plate absorption tower and washes it with alkali liquid to obtain by-product sodium hypochlorite, which is absorbed by the alkali liquid. The exhaust gas after discharge can reach the national allowable discharge standard. Other companies have also used the same method to control chlorine gas and achieved good results. The dust emitted by the metallurgical furnace and kiln contains a small amount of metal dust, which not only pollutes the environment, but also causes metal loss. Gansu Jinchuan Nonferrous Metals Co., Ltd. has added a large number of electric dust collection facilities to control dust. Flue gas basically controls the hazard of dusty smoke. Wastewater treatment and smelting process discharges a large amount of wastewater, which pollutes the environment. Therefore, the treatment of wastewater is also a very important issue. The Chengdu Electric Metallurgical Plant uses the ion exchange technology to treat the process wastewater, which is very effective. Ganchuan Jinchuan also has a sewage treatment station that protects the environment. In the mining, selection and smelting process of mining enterprises, a large amount of waste rock, tailings, waste residue and waste heat are discharged every year. How to effectively use it is a very difficult problem. Now some waste residue and waste heat are also utilized. Quzhou cobalt smelting plant uses arsenic and cobalt ore as cobalt raw material. Because arsenic is a highly toxic substance, they pay special attention to labor protection and environmental protection work, do a lot of work on environmental protection, and have accumulated rich experience in reducing arsenic pollution. And achieved remarkable results, basically meeting the national standards for exhaust gas and wastewater discharge. With the emphasis on environmental issues and the rapid development of science and technology, the "three wastes" will be more effectively managed and the environment will be effectively protected.
