Distribution of Valuable Metals in Various Horizons of "Trepça" Mine

Abstract

Trepca mine in Stanterg dates from 1930 as giant mining complex, and it is known across the world with a high grade of Pb, Zn and Ag minerals. Furthermore, this mine is enclosed by mineralogy zones with high grade of ore and considerable reserves. In this paper will be discussed variable grade of ore taking into account the orebodies which are dipping at considerable depth under the earth crust. Evaluation and definition of geological resources in deposit is done on the research and production phase. During the exploration phase, the knowledge in regard to mineral resources will make clear the point of view on aspect of ore grade. Whereas, during the production phase is more realistic data on ore grade are available. Evaluation of ore grade and resources of a particular deposit, planning and control of grade are the first three actions are important during exploitation phase of mineral resources. Moreover, mine planning for long or short term has an impact on evaluation process. In this paper are conducted several ore bodies and are taken many samples during the production phase in various horizons.
