process of preparing metallic lead from partially desulphurized lead concentrates and scrap metal from lead acid and metallic lead thus obtained

摘要

"METAL LEAD PREPARATION PROCESS FROM PARTIALLY DEHOLIDATED LEAD CONCENTRATES AND SOUND-LEAD BATTERY SCRAPS OBTAINED". The present invention relates to a process of preparing metallic lead from partially desulphurized lead concentrates and used lead acid batteries. This process allows various sources of lead to be used interchangeably to produce refined lead and its alloys with economic advantages. The present invention further relates to metallic lead and its alloys obtainable by said process.
