Electrochemical Extraction of Pb and Zn
from Raw Mineral Materials Using
Sulfurgraphite Electrode

Abstract This paper presents the results of electro-leaching of lead and zinc by an
electrochemical method from raw mineral materials using a sulfurgraphite electrode
as a cathode. Extraction of metals from the hardly refractory sulfide intermediate
product requires a change in technological conditions in accordance with the structure
and physicochemical state of compounds containing the base metal. The result of Xray phase analysis showed that the metals contained in the raw mineral materials are
in the form of sulfides. The initial concentration of sodium hydroxide during leaching
in solutions was 0.1 and 0.5 M. The duration of the electrochemical leaching was
5 h. The maximum extraction during leaching of the concentrate for zinc is 42.15%
and for lead 61.65% in 5 h. A brief description of the raw mineral materials used in
the Shalkiya deposit is given. It has been established that the use of a sulfurgraphite
electrode as a cathode has a positive effect in the electrochemical leaching of lead
and zinc from the concentrate.

Introduction
Waste management is the weakest point in modern metallurgical industry. A feature
of the modern mineral resource base of the Republic of Kazakhstan is the complexity
of both chemical and material compositions. In addition, difficulties are caused by
the lack of real ideas on the formation of the material composition of metallurgical
waste, which occurs as a result of the impact of technological regimes on processed
raw materials. In most cases, stable chemical formations are formed (e.g., eutectic
reactions of slag formation of pyrometallurgical processes), which are very difficult
