Environmental impacts of metal ore mining and processing ...

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. Copper mining produces extensive mine wastes and tailings and Co smelting emits approximately

Ore processing and metal extraction

The first stage was to roast or calcine the ore to convert any sulphides to oxides. The ore was then smelted at a higher temperature with an excess of carbon (charcoal) which removed the oxygen as carbon dioxide. As well as requiring a great deal of fuel (temperatures of the order of 1500 degrees C), slags are produced during the smelting and it is easy to lose a high proportion of metal at this stage. Energy was needed to achieve the high temperatures, to crush the ore

Ore processing and metal extraction

ORE PROCESSING INTRODUCTION. In early days, copper was extracted from ore by smelting with charcoal. In the earliest period, it is likely that only rich malachite and azurite ores were used. With this type of ore, there would be little slag left and the process did not require special conditions. For a fuller description of the types of process that might have been employed, click HERE. It is ...

approximately 60 percent of the ore extracted processed as waste (Da Rosa, 1997; Sampat, 2003). Disposing of such large quantities of waste poses tremendous challenges for the mining industry and may significantly impact the environment. The impacts are often more pronounced for open-pit mines than for underground mines, which tend to produce less waste. Degradation of aquatic ecosystems
