| titleOfInvention | A kind of method of Leaching of Antimony in high arsenic purification antimony slag from copper anode mud |
| abstract | The present invention relates to a kind of method of Leaching of Antimony in high arsenic purification antimony slag from copper anode mud, high arsenic of the granularity less than 2mm is first purified into antimony slag and carries out ore grinding, pre-processed after ore grinding, add sodium hydroxide and potassium permanganate, control extraction temperature, extraction time, liquid-solid ratio and mixing speed, reaction carries out separation of solid and liquid after terminating, and obtains the pretreatment fluid and pretreatment slag rich in arsenic；Then sodium hydroxide and vulcanized sodium, control extraction temperature, extraction time, liquid-solid ratio and mixing speed are added in slag is pre-processed, reaction carries out separation of solid and liquid after terminating, obtains the leachate and leached mud rich in antimony.The present invention has antimony leaching rate high, and less containing arsenic in antimony leachate, technique is simple, the advantages such as processing cost is low. |
