Environmental protection and sustainable development are the keynote of enterprise development all over the world. More and more attention has been paid to the recycling of resources. Batteries are used in many devices, and unused batteries can also enjoy the old for new activities in many businesses. But do you know how to recycle used batteries? Today, Xiaobian is going to answer the puzzles in your mind:
After the recovery of waste batteries, they are all used for lead smelting, so lead smelting will definitely be used in lead smelting furnace, which is a common lead smelting equipment now, with large demand and good refining effect. The slag produced by waste battery lead smelting furnace in the process of lead smelting is mainly composed of gangue oxide in lead smelting raw materials and iron and zinc oxide generated in metallurgical process. Its components mainly come from the following aspects:
1. Gangue in ore or concentrate, such as oxide not reduced in furnace charge, silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, zinc oxide, etc.; oxide iron oxide formed by partial reduction in furnace charge, etc.
2. For lining materials eroded by molten metal and slag, such as magnesia and chromic oxide brought by magnesia or magnesia refractories in hearth or electrothermal front bed, the amount of these oxides is relatively small.
3. The gangue component in the flux and mineral raw materials added to meet the smelting needs. Therefore, the proportion of gangue in various raw materials is not necessarily in line with the proportion required by slag making, and it must be mixed with fluxes such as river sand, limestone, etc.
4. Gangue composition brought in by ash with carbon fuel and reducing agent.
That's all for this week. We'll see each other next week.
