Abstract: Lead-acid batteries are commonly used as power sources for critical operations in the world. They find application in air-traffic control towers, uninterruptible power supplies (UPS), railroad crossings, military installations, hospitals, and weapons systems. Lead-acid batteries are also known as automotive batteries and industrial batteries. Lead-acid batteries consist of large amounts of lead, sulphuric acid, and plastics. The acid is tremendously irritant and a carrier for soluble information. The lead must control because of a range of adverse health effects. Thus, a collectible system that is easily accessible for waste batteries is needed. In this paper, a sustainable model is proposed for the leaching of lead-acid battery slag. The aim is to optimize the leaching of lead-acid batteries slag with natural materials. The leaching characteristic of the lead smelting slag produced using sepiolite and illite. A 2 3 full factorial design model is used to investigate the combination of the effect of variable factors.
