Investigation of Technological Process of Getting Lead Dust From Sulfide-Polymetallic Concentrates
This paper presents a new method for extracting lead and other metals from lead-polymetallic concentrates. The method is based on sulfidic boiling of concentrate. After boiling other processes are done, such as cementation, electrolysis or elution, which help to almost fully extract lead, zinc, copper, iron etc. Suggested method is much less costly compared to other methods – agglomeration-drainage, electro melting, alkaline melting, reaction meltingetc. Based on experimental data, environmental effects are within internationally accepted safety standards. The method is scalable and can be used for other kinds of polymetallic concentrates.
