This paper aims to present an innovative method for the fire refining of lead, which enables the retention of tin contained in lead from recycled lead–acid batteries. The proposed method uses aluminium scrap to remove impurities from the lead, virtually leaving all of the tin in it.
This alloy is an ideal base material for the production of battery grids. This research was carried out on an industrial scale, which confirms the possibility of facile implementation of the method in almost every lead–acid battery recycling plant in the world.
The costs of lead refining using aluminium scrap are higher compared to other classical lead refining methods . From an economic point of view, this new refining method is profitable to use when there is a significant amount of tin in the lead and relatively low contents of other impurities.
The proposed method of refining secondary lead offers the possibility of using the tin already contained in the lead alloy, significantly reducing its consumption for the production of lead alloys for the battery industry. Instead of pure aluminium, aluminium scrap can be used successfully, provided its composition is controlled.
The method of refining the lead–tin alloy proposed by the authors classically begins with the process of drossing the lead. This process is based on the low solubility of copper, nickel, and cobalt in lead at low temperatures. It is conducted in refining kettles, where the lead is stirred and cooled to a temperature of about 350 °C.
For the recovery of lead from solution, although it can be achieved by cementation using iron powder, this method has the disadvantages of large iron powder entrainment and a low lead recovery ratio. In the case of electrowinning, the power consumption is often high.

Spent lead–acid batteries have become the primary raw material for global lead production. In the current lead refining process, the tin oxidizes to slag, making its recovery problematic and expensive.

Today, old car batteries are recycled, with most of the lead used to produce new batteries. But battery technology is changing rapidly, and the future will likely bring new, more efficient options. At that point, the 250 million lead-acid batteries in US cars today will become waste—and that could cause environmental problems.

2.1 Materials. Lead acid batteries were broken to smaller particles and separated from the internal and the external plastic covers. Sludge particle sizes in the range of 4–8 mm (Fig. 1) were put in a titanium basket and employed as the anode in the electrolytic cell.The different components and phases that exist in the sludge particles were examined by …
Secondary lead, i.e. material produced by the recycling of lead-acid batteries has become the primary source of lead in much of the world. This has been important to the secondary lead industry as other uses have dwindled, e.g. lead based pigments, chemicals, fuel additives, solders and CRT glasses [1] .

Lead-acid batteries are the oldest type of rechargeable battery and have been widely used in many fields, such as automobiles, electric vehicles, and energy storage due to the features of large power-to-weight ratio and low cost (Kumar, 2017).Lead-acid batteries account for ~80% of the total lead consumption in the world (Worrell and Reuter, 2014; Zhang et al., …
Overview Approximately 86 per cent of the total global consumption of lead is for the production of lead-acid batteries, mainly used in motorized vehicles, storage of energy generated by photovoltaic cells and wind turbines, and for back-up power supplies (ILA, 2019). The increasing demand for motor vehicles as countries undergo economic development and …
separating the component parts of the batteries, and smelting and refining the lead components. The plastic components may be washed then shredded or melted to make new products. The sulfuric acid electrolyte may be purified or treated, then disposed of or recycled (9). Lead can be released at all stages of the recycling process. Draining the lead-contaminated electrolyte, or …
