Abstract
The paper will show the results of the geochemical tests on composite samples and samples taken from boreholes made in the last few years.
Old inactive waste dumps occupy an area of about 0,39 km2 and contain about 10 million tons of sterile mass, the mean depth of these dumps is 9,2 m. While in recent active dumps are deposited around 4 million tons sterile mass.
The elements show different concentrations in grain - size different parts of the deposited material. Pb, Zn and Mn show maximum concentrations in sandy part and slightly lower in the clay part of the old inactive waste dumps Probistip.
Average content of Pb and Zn in sterile mass deposited in tailing dumps of mine Zletovo is 0,37 % Pb and 0,32 % Zn, so in the not too distant future exploitation could be done the of these valuable components of this removed material with the proper technique.
The concentration of Fe in all composite samples from the boreholes is high, average Fe content is 8.32 % (from 7.09 to 9.54%). The concentration of Mn in sterile mass is also high, ranging in the interval from 3.52 to 5.60%.
Also within the sterile mass deposited in the mine tailing dumps Zletovo some accompanying metals such as Ge, Ga, Cd and In are present, whose application in the course of history was not known so they were not exploited and concentrated in the sterile mass.
key words: Polymetallic deposit Zletovo, Tailing dump, Average content, Pb, Zn, Fe, Mn, Heavy metals, Value assessment.
