In this article we will provide a detailed and informative explanation of the process of lead ingot production in a battery recycling facility. The recycling process can be broadly divided into five stages: pre-treatment, breaking and separation, smelting, refining, and ingot production.
A lead-acid battery is a type of rechargeable battery used in many common applications such as starting an automobile engine. It is called a “lead-acid” battery because the two primary components that allow the battery to charge and discharge electrical current are lead and acid (in most case, sulfuric acid).
The ease with which the lead–acid battery is recycled has made the lead–acid battery the captive user of most secondary lead. Moreover, technologies have been developed in the last few decades that enable recycling of other components of a lead–acid battery such as acid and plastic and these will further ease environmental concerns.
1. Pre-treatment: The first step involves collecting and sorting used lead-acid batteries, which are typically sourced from automotive, industrial, and stationary applications. The batteries are sorted based on their type, size, and condition.
When the ingots are cool, they are removed from the molds and sent to battery manufacturers, where they are re-melted and used in the production of new lead plates and other parts for new batteries. Used battery acid can be handled in two ways.
When there is a lead recycling plant close to a battery manufacturing facility the purification of recovered battery acid by solvent extraction becomes practicable . After removal of iron, antimony, organics and particulates the purified acid can be re-used as electrolyte in new batteries.

Part 2: Recycling Lead-Acid and Li-ion
Lead parts—lead grids, lead oxide and others—are cleaned and heated inside smelting furnaces at a temperature from 1,000 to 1,250°C. Sodium hydrogen carbonate can be added in liquid form for supplementary purification from metal residuals. The molten lead is then poured into ingot molds where the impurities float to the top and are scraped away.

How to Store a Lead-Acid Battery
How long can a lead-acid battery be stored? A lead-acid battery can be stored for up to two years. However, it is important to note that all batteries gradually self-discharge over time, which is known as ''calendar fade.'' Therefore, it is essential to check the voltage and/or specific gravity of the battery and apply a charge when the battery falls to 70 percent state-of …
