| titleOfInvention | Method for performing hydrothemal regulation and control on refractory and fine-grained vulcanization slag to optimize flotation behavior thereof |
| abstract | The invention discloses a method for performing hydrothemal regulation and control on refractory and fine-grained vulcanization slag to optimize flotation behavior of the difficultly-selected and fine-grained vulcanization slag. The method comprises the following steps: putting the refractory and fine-grained vulcanization slag with poor crystallization effect into a hydrothemal reaction kettle; adding a certain amount of water; and realizing crystal form control over artificial sulfide under a high-temperature and high-pressure condition to improve floatability of metal sulfide. A hydrothemal regulation and control technology is as follows: a mineralizing agent and a crystal form modulating agent are added, so that the hydrothemal reaction temperature is improved, multiple regulation and control means, such as crystallization reaction time, are controlled, so that high-efficiency crystallization and growth of the metal zinc sulfide are realized. By adopting the crystal form regulation and control technology, a floating recovery rate of zinc in the refractory and fine-grained vulcanization slag is improved from the original 32.64% to 72.78%. The method is used for recycling valued metals in tailings as well as effectively removing heavy metals in waste slags. |
