Изобретение относитс  к способу получени  лити  из сиодумена. Известный сиособ получени  лити  из сподумена восстановлением его алюминием или ферросилицием в ирисутствии извести провод т при температуре выше 1200°.This invention relates to a process for producing lithium from siodumene. The known method of producing lithium from spodumen by reducing it with aluminum or ferrosilicon in the presence of lime is carried out at a temperature above 1200 °.

Описываемый способ но насто ндему изобретению снижает на 50-80° темиературу процесса и не требует установки диффузионного насоса.The described method but the present invention reduces the temperature of the process by 50-80 ° and does not require the installation of a diffusion pump.

.Отличительна  особенность предложенного способа получени  металлического лити  заключаетс  в том, что ис.ходное сырье восстанавливают в присутствии извести карбидом кальци  в весовом отношении сиодумена к карбиду кальци  1 : 1,5 или 1 : 1,7.A distinctive feature of the proposed method of producing metallic lithium is that the raw material is reduced in the presence of calcium carbide in a weight ratio of siodumen to calcium carbide of 1: 1.5 or 1: 1.7.

Ввиду того, что в литинсодержащих рудах или концентратах содержание окислов кремни  и алюмини , больше чем окислов щелочных металлов , поэтому нри.ходитс  в шихту добавл ть окиси кальци  больше, чем карбида кальци . В св зи с этим от 30 до 5Э% карбида кальци  может быть заменено известью.Since the content of silicon oxides and aluminum oxides in lithin-containing ores or concentrates is higher than alkali metal oxides, it is therefore necessary to add more calcium oxides to the mixture than calcium carbide. Therefore, from 30 to 5%, calcium carbide may be replaced by lime.

Использование карбида кальци  в качестве восстановител  в процессе получени  лити  увеличит срок службы печей благодар  снижению температуры процесса, снизит стоимость полученн  лити  и улучшит показатели процесса рафинироваии  лити .The use of calcium carbide as a reducing agent in the process of obtaining lithium will increase the service life of the furnaces by lowering the process temperature, reduce the cost of lithium produced and improve the performance of the lithium refining process.

Предмет изобретени Subject invention

Способ получени  металлического лити  восстановлецием исходного сырь , например сподумена, в вакууме в ирисутствии извести, отличающийс  тем, что Б качестве восстановител  беретс  карбип кальци  в весовом отношении (например, сиодумена к карбиду кальци  1 : 1,5 или 1 : 1,7).The method of obtaining lithium metal by reducing the raw material, for example spodumene, in vacuum in the presence of lime, characterized in that calcium carbip is taken as a reducing agent in a weight ratio (for example, siodumen to calcium carbide 1: 1.5 or 1: 1.7).
