Title:
電解質の需要が減少した鉛蓄電池からの鉛の水性回収のためのシステムと方法
Document Type and Number:
Japanese Patent JP7239745
Kind Code:
B2
Abstract:
Lead is recovered from lead paste of a lead acid battery in a continuous and electrochemical lead recovery process. In especially preferred aspects, lead paste is processed to remove residual sulfates, and the so treated lead paste is subjected to a thermal treatment step that removes residual moisture and reduces lead dioxide to lead oxide. Advantageously, such pretreatment will avoid lead dioxide accumulation and electrolyte dilution.
