6 FAQs about [Lead-acid battery busbar lead slag]
How is lead slag produced?
Generation of lead slag Lead slag is a by-product of lead production process, mainly from two ways: lead ore smelting and waste lead-acid battery recovery (Ettler and Johan, 2014). The production of primary lead is a process of extracting lead from lead sulfide concentrate by smelting.
What is slag in pyrometallurgic process?
The pyrometallurgic process that the exhausted batteries are submitted for the recovery of metallic lead generates great amount of a by-product called slag. The slag is composed mainly of iron (≈60%) and lead (≈6%), and this residue cannot be disposed in conventional landfill due to the high lead content.
How to use lead slag?
Through the above discussion, there are two ways to utilize lead slag: metal recovery and used for construction materials. It is believed that the environmental, economic and technic feasibilities are the major factors in deciding the suitable process for utilization of lead slag.
What are the contents of a lead-acid battery?
The contents of a lead-acid battery are the sulfuric acid and lead sulfate battery paste, the metallic and oxidic lead grid parts, the plastic battery casings, and the silica separators. Although the methods have changed over the years and vary from plant to plant, the batteries must initially be broken and separated.
Is lead slag a solid waste?
Lead slag is a solid waste with a high iron content, and iron exists in a complex form. Based on the aforementioned results, iron in lead slag was recovered by direct reduction after magnetic separation. Lead and zinc are effectively volatilized under high temperature reducing conditions.
Can a lime slag be replaced with barite?
While desulfurization decreases lead losses, the slags can contain enough to not pass the TCLP. A similar result can be achieved with modern addition of barite. Lime rejects lead sulfide from the slag and reduces it to metallic lead. Replacing lime with barite gives a lower temperature and more-fluid slag.
