| titleOfInvention | A kind of expandable graphite processing method without waste water and slag discharge |
| abstract | The invention discloses an expandable graphite processing method without waste water and slag discharge. (1) graphite powder, concentrated sulfuric acid and oxidant are uniformly stirred to prepare a graphite mixture; (2) the graphite mixture is put into a flotation cell and placed in a flotation cell. Fresh water is added to the flotation tank to carry out a washing and flotation, and the flotated primary foam material is scraped into the foam collection tank, and fresh water is added to the foam collection tank for secondary jet flotation, and the secondary foam material is flotated. After the material is vacuum filtered and dried, the finished product of expandable graphite is obtained, and the waste water obtained after the secondary jet flotation is returned to the flotation cell for recycling; (3) the waste water obtained after the first washing and flotation is repeatedly added to the graphite mixture to recycle the waste water. , when the acid concentration in the waste water reaches 60-70%, the waste water is poured into an acid tank for filtration and separation, the obtained solid impurities are recycled, and the waste acid solution separated in the acid tank is added with apatite powder to react to prepare fertilizer. In the process of processing the expandable graphite, the invention does not discharge waste water and slag, so it is environmentally friendly. |
