Реферат | A possibility of iron sands beneficiation by magnetic separation in different circuits, flotation and washing has been studied. Iron sands hydrochemical beneficiation alternatives have been investigated. Caustic alkali concentration, temperature and leaching process duration effects on alumina recovery have been studied. A possibility of iron sands leaching by alkali-aluminate solutions, achieving iron oxide content of 70–73 %, is shown. |
Ключевые слова | Iron sands, classification, magnetic separation, hydrochemical beneficiation, leaching, tricalcium aluminate hydrate. |
