  • MINERAL ECONOMICS - Underground mining .

    The uniqueness of minerals as economic products accounts for the complexity of mineral economics and the business of mining (Vogely, 1985; Strauss, 1986). Minerals are unevenly distributed and, unlike agricultural or forest products, cannot reproduce or be replaced. A mineral deposit may therefore be considered a depleting asset whose production is restricted to the area in which it occurs ...
