Abstract. Mining operations, including crushing, grinding, smelting, refining, and tailings management, are a significant source of airborne metal and metalloid contaminants such as As, Pb, Cd and other potentially toxic elements. Dust particles emitted from mining operations can accumulate in surrounding soils, natural waters and vegetation at ...

Jul 24, 2020 Abstract. Mining operations determine a long-term production schedule, often to maximize net present value. For a time horizon of between years and decades, optimization models seek the extraction times—with monthly or yearly fidelity—of three-dimensional, notional blocks of ore and waste within a deposit to satisfy spatial precedence ...

Abstract. Opencast mining operations involve huge quantities of overburden removal, dumping and backfilling in excavated areas. A substantial increase in the rate of accumulation of waste dumps in recent years has resulted in greater height of the dump for minimum ground cover area and also given rise to danger of dump failures.

Abstract. The technical feasibility of deepsea mining operations of polymetallic nodules in 5,000m+ water depth has been demonstrated through a number of pilot tests done in the later 1970s and early 1980s. Since then, there have been significant technological advances, especially those in the offshore deepwater oil and gas exploration and ...

Abstract. This article examines local-level community development (CD) facilitated by the mining industry. It moves beyond polarized debates that pit CD in mining as either a front for public relations or a genuine attempt to facilitate development in order to build understanding and critical awareness of problems and possibilities of local-level CD practice.
