Предлагаетс способ извлечени олова из бедных оловом мате;)иалов путем возгонки в виде сульфидов. В качестве :сульф 1дизатора примен ют пиритный концентрат, сернистое железо или элементарную серу. Процесс ведут в кип щем слое толщиной 1 м при 930-ОЗО и концентрации элементарной серы в газах 1,5-2,OVo. Исходны) материал предварительно гранулируют до крупиостц частиц 0,5-2,0 мм.A method is proposed for extracting tin from tin-poor mate;) yals by sublimation in the form of sulphides. As: sulfide 1dizer, pyrite concentrate, iron sulfide or elemental sulfur are used. The process is carried out in a fluidized bed with a thickness of 1 m at 930-OZO and the concentration of elemental sulfur in gases 1.5-2, OVo. The initial material is pre-granulated to a particle size of 0.5-2.0 mm.
