| titleOfInvention | A kind of recycling method of silicon powder |
| abstract | The invention discloses a method for recycling silicon micropowder. A recovery agent is added to the recovery tank of the precipitate, and then deionized water is added to obtain a first mixed slurry; an acid solution is added to the first mixed slurry, stirred at a uniform speed, and allowed to settle for stratification to obtain a recovery agent layer; The layer is put into the recovery tank for heating, the recovery agent is heated and evaporated into the condensation tank, and after condensation, it is recycled for the next use; after adding clean water to the recovery tank for 2 to 3 times, filtering and drying to obtain the recovered silicon micropowder . The invention does not pollute the environment, the recovery agent can be recovered and reused, the recovery cost is saved, and the recovery efficiency is effectively improved. |
