Description
Изобретение отно ситс к способам солевого хлорировани бедного оловосодержап;его сырь .The invention relates to methods for the salt chlorination of a poor tin-containing raw material.
Известно, что дри солевом хлорировании бедного оловосодержащего сырь исходный концентрат смешивают с хлористым кальцием и коксом и нагревают до тем1пературы 800°С. Оснавным недостатком известного способа вл етс сложность обеспечени хороших условий тепло- и вдассопередачи.It is known that the dry salt chlorination of a poor tin-containing raw material initial concentrate is mixed with calcium chloride and coke and heated to a temperature of 800 ° C. A fundamental disadvantage of the known method is the difficulty of providing good heat and void transfer conditions.
Дл улучшени условий проведени процесса предлагаетс проводить его -в расплаве хлористого кальци .In order to improve the conditions of the process, it is proposed to conduct it in a calcium chloride melt.
Пример. Смесь из 30 г хлорируемого материала и 3 г твердого восстановител суспензируют инертным газом или механически в 100 г расплавленного хлористого кальци . При температуре 900°С в течение 2 час более 95Vo олова отгон етс в виде хлоридов. Содержание олова в остатке составл ет дес тые доли процента.Example. A mixture of 30 g of the material to be chlorinated and 3 g of a solid reducing agent is suspended with an inert gas or mechanically in 100 g of molten calcium chloride. At a temperature of 900 ° C for 2 hours, more than 95 Vol of tin is distilled off as chlorides. The tin content in the residue is tenths of a percent.
