Abstract

The cooper ore reserves of Ro Еџia Poieni deposit (Romania) represents about 40% of the national cooper ore, that importance increasing with the actual rising cooper price on the international market. Deposit mineralization is located within the Fundoaia andesitic ore body and appears mainly on a system of fractures, or as uneven distribution impregnations in andesitic rocks. The mini ng of this cooper deposit began in 1977 and in 1985 reaching about 9 million tonnes of or e capacity and in 1988, 15 million tonnes. Currently, operational works are carried out at the level + 910m and it is expected to develop the open-pit mining to the level +745m, afterwards moving to the combined extraction of the deposit, namely the open pit and underground mining.
