Customer ServiceSince the treatment of slag and anode slimes was not complete, the accuracy of the cost estimate may not be within the assumed ±30 pct. Capital cost was $21 million, and the operating cost per kilogram of lead recovered was 35.2 cents (16.0 cents per lb), excluding the cost of scrap batteries. Conclusions. High-purity lead was recovered from
Customer ServiceCampine introduces new process for antimony extraction from ULABs that combines the recycling of lead-acid batteries and the manufacturing of antimony trioxide," said Hilde Goovaerts, head of metallurgical technology at Campine.

Customer ServiceWork at the Bureau of Mines Rolla Research Center has resulted in the development of a nonpolluting and energy-efficient method for recycling all the lead in scrap batteries (fig. 1). The lead metal, separated by screening, is melted and cast into anodes for electrorefining using a modified Betts pro cess.
Customer ServiceThis work presents a new methodology for the extraction of lead from slag, based on the complexing effect of EDTA, a chelating ligand that has the ability to solubilize several heavy metals.
Customer ServiceThe lead recycling process is of great interest in the lead industry. Nowadays, more than 50% of the overall world lead production comes from secondary lead smelters. The main raw material for this process is used lead-acid batteries ( ISRI Rains) and lead scrap ( ISRI Radio). Roughly, about 90% of scrap batteries are recycled.
Customer ServiceOver the past 20 years, a significant number of processes have been developed to recover lead from scrap batteries. These processes recover lead via hydrometallurgical processing of the paste component of the battery followed by electrowinning. A number of pilot plant operations have been conducted, but thus far none of the processes have become operational.
Customer ServiceThis study presents a clean process for recycling spent lead-acid battery paste. The lead in paste was recovered via hydrometallurgical leaching and electrowinning in chloride solution.
Customer ServiceLead-acid batteries are the oldest type of rechargeable battery and have been widely used in many fields, such as automobiles, and 2 h leaching time. A linear increase in the lead extraction was observed. The lead leaching ratio was only 75.8% at 50 °C and increased to a maximum at 90 °C. Thus, 90 °C is the preferable temperature for maximizing the lead leaching

Customer ServiceAt the smelting step, named pyrometallurgical process, the lead compounds from the break are reduced to provide metallic lead with low antimony content, by smelting the battery paste (lead oxide/hydroxide/carbonate, with a small amount of sulfate) with coke or other reducing agent rich in carbon and sodium hydroxide (NaOH) and sodium nitrate
Customer ServiceUsually, spent lead-acid batteries are separated in lead recycling plants by dismantling and sorting into four fractions: lead paste, metallic fragments, waste acid, and plastic case ( Worrell and Reuter, 2014; Zhang et al., 2019 ). The processing of lead paste is relatively complex because it contains refractory lead sulphate.
The material is processed via reductive leaching using calcium chloride and ferrous ions to extract the lead from lead paste. The lead in the leaching liquor can be recovered as metallic lead powder via electrowinning using soluble anode (iron sheet).
The average concentration of lead in wastewater is about 3–15 mg/L and the pH of wastewater falls in the range of 1.6-2.9 [ 9 ]. If the battery wastewater is not treated well before discharge to environment, lead can contaminate food and water, and be present in nature.
Lead acid battery (LAB) recycling benefits from a long history and a well-developed processing network across most continents. Yet, LAB recycling is subject to continuous optimization efforts because of increasingly stringent regulations on process discharge and emissions.
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.
The removal efficiency of lead was increased after using a carbonation step with 68% for quicklime and 69% for slaked lime. The carbonation process not only enhanced the lead removal efficiency in the battery wastewater but also reduced pH to meet requirements of environmental regulations.
