Environmental Impacts of Metal Ore Mining and
1997-5-1 Abstract. The impact of mining and smelting of metal ores on environmental quality is described. Mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material. In the metal industry, production of Cu, Pb, and Zn causes the greatest degradation of the environment.

Effects of iron-ore mining and processing on metal ...
2017-8-28 Mining and associated smelting and metal processing activities have led to perturbations in the cycling of metals in the surface environment. In this context, iron-ore mines act as important sources of major metals, mainly Fe and Mn, but also associated trace metals into the environment (Ratha and Venkataraman 1995; Wong 1981; Zabowski et al. 2001).

Instead, a novel and cheap method was adopted which contributed greatly to the success of the Alderley Edge Mining Company and enabled low grade (1.5 to 2% copper) to be worked. Ore was crushed between iron rollers driven by the steam engine and then placed in wood- or stone-sided boxes floored with perforated boards covered with brushwood and straw.
