Method for recovering tin from tin smelting furnace waste bricks
The invention relates to a method for recovering tin from waste bricks of a tin smelting furnace. The method comprises the following steps: (1) crushing and finely crushing the waste bricks of the tin smelting furnace; (2) putting the finely-crushed waste furnace bricks into a ball mill for ball milling; (3) the ball-milled waste furnace bricks are conveyed to a shaking table to be subjected to waste brick and tin separation after being subjected to water mixing and slurrying, and low-degree tin sand and the waste furnace bricks are obtained; and (4) the low-grade tin sand is returned to the tin smelting technological process, and waste furnace bricks are sold. The method is simple in operation condition, high in mechanical automation degree, short in process and environmentally friendly in production process, tin metal in the smelting waste bricks can be fully recycled, the recycling rate is larger than 91%, and meanwhile the smelting waste bricks obtained after tin selection can be recycled.
本发明涉及一种从锡冶炼炉窑废砖中回收锡的方法，包括以下步骤：(1)将锡冶炼炉窑废砖破碎、细碎；(2)将细碎后的废炉砖投入球磨机进行球磨；(3)将球磨后的废炉砖调水浆化后，输送至摇床进行废砖与锡分离，得出低度锡砂和废炉砖；(4)低度锡砂返回锡冶炼工艺流程，废炉砖外售。本发明的方法操作条件简单、机械自动化程度高、流程短，生产过程环境友好、可充分回收冶炼废砖中的锡金属，回收率大于91％，同时选锡后的冶炼废砖可实现资源化。
