POSSIBILITIES TO RECOVER ALUMINUM FROM MINING WASTE DUMPS LOCATED IN JIU VALLEY. ECONOMIC, SOCIAL AND ENVIRONMENTAL OPPORTUNITIES

English abstract

The exploitation of low-grade ore deposits or the recovery of useful minerals from old waste dumps and tailing ponds is considered as an interesting economic opportunity especially in the context in which we speak more and more of a reduction in availability of some mineral resources or depletion of conventional ore deposits. The exploitation of old waste dumps and tailing ponds is possible on the one hand due to progress in terms of processing technologies (process efficiency and by lowering the minimum useful content that can be recovered) and on the other by the rise in the demand and the price on the internal and international markets for some useful mineral substances. This paper presents some considerations related to the opportunity to extract useful mineral substances, more precisely aluminum, contained in coal mining waste dumps from Jiu Valley (Romania), regarded in terms of economic, social and environmental benefits.
