Abstract: Mining waste at Balya (Balıkesir) was studied, divided in two categories, flotation, smelting.90 flotation samples, 14 smelting samples from the waste were collected to analyse the valuable elements. XRFresults show that the flotation waste has an average of 4.38 wt% Pb, 4.1 wt% Zn, 8.48 wt% Fe, 0.29 wt% Cucontent; while the smelting waste includes an average concentration of 3.16 wt% Pb, 11.08 wt% Zn, 26.53 wt%Fe, 0.22 wt% Cu. The chemical data related to the waste were interpreted by statistical analysis. Using thedetermined geostatistical parameters, the area variation on the basis of grade was determined using the OrdinaryKriging method. Quantity, tonnage, density, tonnage change values of the mining waste were used in theconstructed block model. The amount of the possible reserves of the waste was then determined. A resource of516,674 tons for the smelting, flotation waste was assessed. Excluding Fe, Cu, this study revealed that miningwaste in the Balya region has an operable content of Pb, Zn. However, more detailed research, developmentwork is required for the recovery, disposal process of the Pb-Zn-rich areas, due to the presence of some sulphateminerals (bassanite, anglesite), the oxidation processes, the partial sedimentation heterogeneous structureof these wastes.
