ABSTRACT

The Tenka deposits (which include Tenka 1, Tenka 2, and Tenka 3 deposits, located in
eastern Serbia) belong to polymetallic deposits and besides the copper they contain lead
and zinc minerals in a certain content. From this perspective, defining optimal ore
processing conditions (due to complex ore characteristics) and obtaining commercial
product with satisfactory technological properties, represents complex task and requires
serious research and examinations.
This paper presents a part of technological investigations performed to determine the
possibility of copper and precious metals valorization from the ore deposit Tenka 3,
using a flotation concentration method. During the experimental procedure, sodium
isopropyl xanthate was used as the collector, while the pH value of flotation pulp varied
from 9.9 to 11.6. The results shown that the satisfactory recoveries of copper and
precious metals could be obtained by this procedure (at the appropriate pH value of
pulp), but the quality of the rough flotation concentrate was basically low.

Keywords: copper, precious metals, flotation, sodium isopropyl xanthate.
