Extraction of lead metal is less complicated than copper and the dominant method is through pyrometallurgy. Metalcess can design production line of different capacity to suit customer requirement, either lead concentrate or recycling project of spent lead acid battery, lead containing slag and residue, lead containing glass (CRT screen), etc. With different smelting and processing methods, the customer get various of final products such as cathode lead ingot, lead oxide powder, lead paste, lead plate, lead tube as well as other byproducts like sulfuric acid and precious metals from anode slime.
Major steps of lead smelting are presented in the following table.

Product |
For recycling of secondary battery, for example, Spent Lead Acid Battery, it requires a breaking and separation system to separate lead-containing parts from plastics and other non-metal parts. Lead- containing parts can be refined in a separate smelting system or treated together with other lead material like lead concentrate or lead slags, depending on its capacity, product requirement, etc.
Metalcess provides you the integrated system for either lead concentrate or secondary lead. Focusing on maximizing productivity and minimizing overall cost, Metalcess aims to provide our customer with the most optimized solution, reliable equipment and attentive service to your smelting project. Consultation service and inquiries to start new project are available at customer request.
