VALORIZATION OF MINING WASTE IN THE CONSTRUCTION INDUSTRY GENERAL CONSIDERATIONS

PhD Student Larisa Chindris, Ph.D., Prof. Victor Arad, Ph.D., Prof. Susana Arad

Abstract

Following mining and processing activity, results a significant amount of mining wastes, in the form of sterile mineral. These wastes are stored largely in mining tailing ponds or heaps. The chemical composition of the sterile material depends from one mining site to another. For long time worldwide, tailing deposits were considered waste deposits, without the possibility of future use. A few of the negative effects on the environment my constructing and exploiting mining tailing ponds, heaps, landfills, are the destruction of a large area of terrain, pollution of surface waters or underground waters with chemicals dissolved, loss of life in case of structural failure. The current aim is to achieve and determine though global research programs the possibility of using mining waste from mine tailing in various domains. The main focus area is that of construction, where mining waste can be used for the production of concrete, or in infrastructure stabilization. Another area where research has been conducted is the possibility of using mining waste as a source of fertilization. Through these methods, terrains occupied by deposits can be entirely cleared.
