After a magnetic separation aiming to recover ferrous metals, the coarse fraction obtained in the pre-treatment process of alkaline and Zn-C batteries contains Zn granules from the negative electrode of Zn-C batteries Fig. 2a , brass granules from the current collector of alkaline batteries Fig. 2b , plastics from gaskets and paper/non-woven fabric/plastic from separators between electrolyte ...
A novel mechanical separation process consisting of shredding, baking, magnetic separation, and specific gravity separation was developed to recycle one metric ton per hour of alkaline batteries at lower cost than current methods, while being environmentally beneficial.
With this process the recovery of alkaline and related dry cells has sufficient economic incentive to significantly increase the recycling of these batteries. This process eliminates the need to dissolve the steel casing and the reduction and solution of the manganese oxides.
Alkaline Battery Life Cycle Analysis LCA w/ EOL Potential: AA Alkaline Battery separated components Each component of the individual battery is input to CES software Figure 4 along with its manufacturing process if any and transport. The program does not take into consideration the assembling of the final product.
Recycling process: 1. Batteries breaking: batteries are broken in a hammer mill or another type of crushing machine. 2. Separation by different density in the water The pieces from the breaking process are placed in a tank, where the dissimilar densities of the materials cause some to sink lead , some to float hard rubber
COMPOSITION: Alkaline batteries have a zinc anode and a manganese dioxide hode. The electrolyte used in an alkaline battery is a paste of either potassium hydroxide or sodium hydroxide. Each of these components, along with conductors and separators are then assembled into or contained within a hermetically se aled unit. Typical
Each facility employs an innovative recycling process utilising proprietary in-house technology and equipment. Auto punching machines and shredders break end-of-life batteries down into fine substances. Magnetic separators recover the copper and aluminum, and a chemical treatment process is used to recover commodity-grade cobalt and lithium.
