Determination and monitoring of ore recovery and dilution coefficients in Sasa lead and zinc mine - M. Kamenica, R. Macedonia

Abstract

In this paper, proceeding of determination and monitoring of ore recovery and dilution coefficients in lead and zinc mine 'Sasa' - M. Kamenica, will be presented. The calculation of these technical and economic excavation parameters were carried out by means of geodetic evaluations and measurements of the volume of excavated and non excavated ore for each stope in the pit.
