Analysis of a more sustainable method for recycling waste lead

Pre-desulfurization technology is the key to the entire process. It uses a desulfurizer to convert high-melting point lead sulfate into low-melting point lead compounds, which effectively reduces SO 2 emissions and smelting energy consumption (Fu, 2007, Li, 2011).At present, desulfurizers used for lead paste pre-desulfurization include NaOH, Na 2 CO

What is a battery desulfation?

This is what desulfation (desulphation)is about. Batteries are subject to an internal discharge, also called self-discharge. This rate is determined by the battery type, and the metallurgy of the lead used in its construction. Wet cells, with the cavities inside for electrolyte, use a lead-antimony alloy to increase mechanical strength.
