digging up ore displaces huge piles of rock and earth. To produce metals the ore is processed which generates immense quantities of waste. The amount of recoverable metal is a small fraction of the total ore mass. For example‚ to manufacture an average gold ring creates 20 tons of waste. Many gold mines use a process known as heap leaching which is dripping a cyanide solution through piles of ore. The

Mills. 11 6. Electrical Problems Caused by large Grinding Mills 12 7. Conclusion 13 7. References 14 Introduction In the mining industry grinding mills are used to crush mined ore. To take advantage of economies of scale‚ more ore needs to be processed in-order for the mine to be more profitable. To process the ore mining operations have adapted large grinding mill drives in the megawatt power range. The power consumption of the large drives has forced designers to look at ways of increasing

mining is productivity. With most of the easily-accessible high grade ores almost tapped out‚ companies are faced with the challenge of either mining low grade ore or mining in remote regions. In the case of low grade ore‚ miners must monitor the incoming material to maximize the extraction process and the waste material must be monitored just as closely to ensure that none of the valuable minerals are lost. The higher grade ores that are still
